手順書の作成方針
手順書は、「ファイルサーバの構築」、「MPDサーバの構築1」、「MPDサーバの構築2」、「運用方法」の順に書いていきます。
yoさん、ゴンザエモンさん、他の方達の多くにおいてはおそらくご存じのことを書いていきますが、
初心者の方もおられると思いますので、ご寛容ください。
また、yoさんのブログから頂いた情報も書いていますが、手順を書くに代え難いものですのでご容赦の程、お願いします。
また、他のブログ等からの情報も参考にしています。
引用先を明示はしませんが、先達の方達には感謝しております。
前提条件および、私の環境について
私のシステム構成は、ファイルサーバ、MPDサーバ、クライアントの3台です。
システムディスク、音楽データにはSSDを使用しています。
SSDを選択した理由は、速いこともありますが電気代が安いからです。
サーバの運用形態が24時間365日稼働ですので。
OSはDebian、ネットワークはnfsを使用しています。
プログラムの開発は行っておらず（但し、MPD、alsa関係のプログラムのコンパイルはしています）、全て既存のものを使用しています。
パソコンはインテルNCUを使用しています。
サーバのスペックとしては、インテル Core i3、メモリ８Gあれば十分だと思います。
「ファイルサーバの構築」
1.Debian Busterのインストール
DebianのサイトからISOイメージをダウンロードし、USBメモリーに書き込み後、
パソコンからDebianをインストールして下さい。
導入機能はSSHサーバのみ、ファイルシステムはXFSがいいと思います。
インストール後、再起動して下さい
・パッケージアーカイブ先の設定
vi /etc/apt/sources.list
以下の行をコメントアウトして下さい。
#deb cdrom:[Debian GNU/Linux 9.5.0 _Stretch_ - Official amd64 DVD Binary-1 20180714-10:25]/ stretch contrib main
・PATHの設定
vi ~/.bashrc
PATH=$PATH:/usr/local/bin:/bin:/usr/bin:/usr/local/sbin:/usr/sbin:/sbin:/home/ohsawa/bin:
export PATH
source ~/.bashrc
・パッケージの更新および関係パッケージのインストール
apt-get update
apt-get upgrade
apt-get install net-tools ※ifconfigを使用するため
apt-get install aptitude
apt-get install samba ※sambaを使用するのであれば（samba設定ファイルの例を最後に添付します）
apt-get install install nfs-kernel-server ※nfsを使用するのであれば必要
apt-get install irqbarance 割り込みのコア負荷分散
apt-get install rtirq-init オーディオ機器に関連するIRQストリームの優先度を上げるスクリプトが含まれています
インストール後、/ etc / default / rtirqファイル、つまり優先度を上げるIRQストリームの
リストを編集する必要がある場合があります。
RTIRQ_NAME_LIST="rtc snd usb i8042"
※不要なサービスを停止するためにsysv-rc-confをインストールされている方も多いと思いますが、停止設定をしてもサービスは停止しません。
サービス停止は、直接停止のためのコマンドを実行する必要があります。
（例） service cron stop
・リアルタイムカーネルのインストール
aptitude search linux-image によりカーネルイメージを探し、インストール
私は以下を選択しました。
aptitude install linux-image-4.19.0-8-rt-amd64
aptitude install linux-image-rt-amd64
・現在のIPアドレスの確認
ifconfig -a
IPアドレスを確認後は、Tera Term等を使用したSSHによるWindowsからの作業となります。
・ネットワークの設定
vi /etc/network/interfaces
※環境に応じて、ネットワーク名、IPアドレスを書き換えてください。
# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).
source /etc/network/interfaces.d/*
# The loopback network interface
auto lo
iface lo inet loopback
# The primary network interface
#allow-hotplug enp0s25
#iface enp0s25 inet dhcp
# This is an autoconfigured IPv6 interface
#iface enp0s25 inet6 auto
auto enp0s25
iface enp0s25 inet static
address 192.168.1.14
network 192.168.1.0
netmask 255.255.255.0
broadcast 192.168.1.255
gateway 192.168.1.1
dns-nameservers 192.168.1.1
・GRUBの更新
vi /etc/default/grub
GRUB_CMDLINE_LINUX_DEFAULの行を以下のように変更し保存
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash threadirqs nowatchdog mitigations=off"
nowatchdog:watchdogの停止
mitigations=off:CPU の脆弱性の緩和策をオフにする
update-grub2
・rootによるログインを可能とする（任意）
rootによるログインは好ましいものではありませんが、
自宅で本人しか使用しないのであればいいと思います。
vi /etc/ssh/sshd_config
PermitRootLoginの行を探し
PermitRootLogin yes とします。
再起動します。
再起動後uname -a にてカーネル名が「linux-image-4.19.0-8-rt-amd64」
になっているか確認して下さい。
再起動後の作業は、Tera Term等を使用したSSHによるWindowsからのものとなります。
・RAIDの構築
※RAIDを使用しないのであれば必要ありません。
[私の場合、SSD3台によるRAID0]
(1)パーティションの確認
fdisk -l
(2)パーティションの作成
fdisk /dev/sda
fdisk /dev/sdb
fdisk /dev/sdc
※全てデフォルトでかまいません。
(3)RAIDの作成
aptitude install mdadm
mdadm --create /dev/md0 --level=raid0 --raid-devices=3 /dev/sda1 /dev/sdb1 /dev/sdc1
mdadm --detail --scan >> /etc/mdadm/mdadm.conf
※注意点
実は、RTカーネルをインストールをしていないでRAID構築後、再起動すると、
/dev/md0が存在せず、/dev/md127と言う名称に変わっています。
この不具合は、RTカーネルをインストール後、/etc/mdadm/mdadm.confを削除し
もう一度、mdadm --detail --scan >> /etc/mdadm/mdadm.conf を実行すると直ります。
・xfsファイルシステムの作成
mkfs.xfs /dev/md0
・マウントの設定
[私の場合]
mkdir /music
vi /etc/fstab
# /etc/fstab: static file system information.
#
# Use 'blkid' to print the universally unique identifier for a
# device; this may be used with UUID= as a more robust way to name devices
# that works even if disks are added and removed. See fstab(5).
#
# <file system> <mount point> <type> <options> <dump> <pass>

#tmpfs /var/log tmpfs defaults,noatime 0 0
#
/dev/md0 /music xfs rw,nosuid,dev,noexec,auto,nouser,async,nofail,noatime barrier=0 0 0
vi /etc/exports（NFSを使用するのであれば）
[私の場合]
# /etc/exports: the access control list for filesystems which may be exported
# to NFS clients. See exports(5).
#
# Example for NFSv2 and NFSv3:
# /srv/homes hostname1(rw,sync,no_subtree_check) hostname2(ro,sync,no_subtree_check)
#
# Example for NFSv4:
# /srv/nfs4 gss/krb5i(rw,sync,fsid=0,crossmnt,no_subtree_check)
# /srv/nfs4/homes gss/krb5i(rw,sync,no_subtree_check)
/music 192.168.1.0/24(rw,async,no_subtree_check)
#
mount -a
chmod 777 /music
・細かい設定
vi /etc/sysctl.d/99-sysctl.conf
vm.swappiness = 10
net.ipv4.tcp_no_metrics_save=1
net.ipv6.conf.eno1.disable_ipv6 = 1
sysctl -えぃｔぃｔp
・sambaの設定ファイル
vi /etc/samba/smb.conf
#
# Sample configuration file for the Samba suite for Debian GNU/Linux.
#
#
# This is the main Samba configuration file. You should read the
# smb.conf(5) manual page in order to understand the options listed
# here. Samba has a huge number of configurable options most of which
# are not shown in this example
#
# Some options that are often worth tuning have been included as
# commented-out examples in this file.
# - When such options are commented with ";", the proposed setting
# differs from the default Samba behaviour
# - When commented with "#", the proposed setting is the default
# behaviour of Samba but the option is considered important
# enough to be mentioned here
#
# NOTE: Whenever you modify this file you should run the command
# "testparm" to check that you have not made any basic syntactic
# errors.

ゴロキさん
音源SSDのストライピングをされている由。ふと、こんなことを思ったのですが、可能なのかな？
１．現状1台のSSDで運用しているが、容量が足りなくなりつつある。
２．容量を倍増させようと思うと高いし、今のSSDが余ってしまう。
３．（例えば）1TBくらいのSSDなら安いし当面の対応ともなるので、現状＋追加の1台で全体容量を拡大して使う。
改めてシステム的にはRAID0を組んで、音源も流し込まねばいけないとは思いますが、、、
No.7395
ゴンザエモンさん、こんばんは
SSDの追加は可能です。
但し、現状と同じ容量のSSDを購入する必要があります。
RAIDは容量の少ない方に合わせて作成されるからです。
（これはRAID0だけではなく全てのRAIDに共通する仕様です。）
例えば、現状のSSDが2TBでも新たに購入したSSDが1TBだと
1TB＋1TB=2TBとなってしまいます。
従って、RAID0を作成するのであれば現状と同じ容量のSSDを購入してください。
手順は以下のとおりです。
１．samba等を利用し現在の音楽データをハードディスク等にバックアップします。
２．2台のSSDでRAID0を構築します。
３．念の為、PCを再起動してRAIDが出来ているか確認してください。
４．バックアップから音楽データをRAID0のSSDにコピーします。

yoさん、皆さん、こんばんは
MPDサーバの構築について、以下に書かせて頂きます。
ただ、考えてみるとMPDサーバの構築はファイルサーバの構築と
ほとんど同じですので、追加、変更箇所のみ書きますね。
「MPDサーバの構築手順」
・NFSを使用している場合
apt-get install nfs-common
vi /etc/sysctl.d/nfs_tuning.conf ※ファイルサーバ側でも行ってください。書き忘れていました。
net.core.wmem_max = 50331648
net.core.rmem_max = 50331648
net.ipv4.tcp_mem = "50331648 50331648 50331648"
net.ipv4.udp_mem= "50331648 50331648 50331648"
net.core.netdev_max_backlog = 5000
・/etc/fstabの編集
mkdir /music
vi /etc/fstab（私の環境）
# /etc/fstab: static file system information.
#
# Use 'blkid' to print the universally unique identifier for a
# device; this may be used with UUID= as a more robust way to name devices
# that works even if disks are added and removed. See fstab(5).

tmpfs /tmp tmpfs defaults,noatime 0 0
・mpdとmpcのインストール
※参考までに、私の/etc/mpd.confの変更箇所を最後に付加しておきます。

yoさん、皆さん、こんにちは
以下に、運用について書かせて頂きます。
「運用手順」
前提として、運用は24時間365日稼働です。
まず、ファイルサーバ、MPDサーバともオーディオ機能はBIOSにてOFFにしてください。
・ファイルサーバ
(1)topコマンドにてusb、ネットワークのデーモンを確認。
私の環境ではUSBは「irq/124-xhci_hc」です。
しかし、何故か再起動すると、 irq/124-xhci_hcが irq/123-xhci_hcや irq/125-xhci_hcに
変わることがあるので/etc/rc.localに書くことが出来ません。
私の環境ではネットワークは「irq/122-eno1」です。
(2)USBコントローラPCIコードを確認
lspci -nn
00:14.0 USB controller [0c03]: Intel Corporation Sunrise Point-LP USB 3.0 xHCI Controller [8086:9d2f] (rev 21)
(3)以下のコマンドを実行
chrt -f -p 99 `pgrep irq/124-xhci_hc`
setpci -v -d *:* latency_timer=b0
setpci -v -d 8086:9d2f latency_timer=ff
chrt -f -p 99 `pgrep irq/122-eno1`
service cron stop
service rsyslog stop
service dbus stop
service exim4 stop

yoさん、皆さん、こんばんは
MPDサーバ、ファイルサーバの設定を一部修正、追加しました。
・/etc/sysctl.d/nfs_tuning.confを削除し、/etc/sysctl.d/99-sysctl.confに統一
内容は以下の通り（MPDサーバ、ファイルサーバ共通です。そして、nfsのudpのみに
関係がある項目がありますが、TCPでは使われないだけで問題ありません）。
私の環境では、以下の設定が最も通信効率がいいようです。
vi /etc/sysctl.d/99-sysctl.conf
vm.swappiness = 10
fs.inotify.max_user_watches = 524288
net.ipv4.tcp_no_metrics_save=1
net.ipv6.conf.eno1.disable_ipv6 = 1
net.core.rmem_default=33554432
net.core.wmem_default=33554432
net.core.rmem_max=33554432
net.core.wmem_max=33554432
net.ipv4.tcp_rmem=33554432 33554432 33554432
net.ipv4.tcp_wmem=33554432 33554432 33554432
net.ipv4.udp_rmem_min=33554432
net.ipv4.udp_wmem_min=33554432
net.ipv4.udp_mem=33554432 33554432 33554432
net.core.netdev_max_backlog=5000
net.ipv4.conf.all.forwarding=1
sysctl -p にて反映
・/etc/mpd.confの一部変更
audio_output {
type "alsa"
name "My ALSA Device"
device "hw:1,0" # optional
mixer_type "disabled" # optional
auto_resample "no" # 追加部分です（関係ないと思いますが、念の為）
use_mmap "yes" #追加部分です
# mixer_device "default" # optional
# mixer_control "PCM" # optional
# mixer_index "0" # optional
dop "yes"
}
・prelinkの導入
mpdサーバ、ファイルサーバの両方にインストールします。
aptitude install prelink
prelink -amR #サーバ立ち上げに実行
※パッケージ更新時には、再度、実行してください。
私の環境ではprelinkの音質向上は大きいものでした。
・ファイルサーバの運用の変更
setpciをUSBからEthernetに変更
lspci -nn
00:1f.6 Ethernet controller [0200]: Intel Corporation Ethernet Connection (4) I219-V [8086:15d8] (rev 21)
setpci -v -d *:* latency_timer=b0
#setpci -v -d 8086:9d2f latency_timer=ff #USBをコメントアウト
setpci -v -d 8086:15d8 latency_timer=ff #Ethernetを追加

yoさん、皆さん、こんにちは
パソコン立ち上げ時のメッセージを確認したところ
intel関係のファームウェアロードエラーが出ていることがわかりました。
エラーが出ても動作に問題は無いようですが、
気持ちのいいものではないのでその解決法を書かせて頂きます。
vi /etc/apt/sources.list
以下を追加
# buster-updates, previously known as 'volatile'
deb http://ftp.jp.debian.org/debian/" target="_blank">http://ftp.jp.debian.org/debian/ buster-updates main contrib
deb-src http://ftp.jp.debian.org/debian/" target="_blank">http://ftp.jp.debian.org/debian/ buster-updates main contrib
deb http://ftp.jp.debian.org/debian" target="_blank">http://ftp.jp.debian.org/debian buster main non-free
deb-src http://ftp.jp.debian.org/debian" target="_blank">http://ftp.jp.debian.org/debian buster main non-free
aptitude update
aptitude upgrade
aptitude install firmware-linux-free
aptitude install firmware-linux-nonfree
上記作業において質問されますが、全てYesで大丈夫です。
作業終了後、再起動
dmesgにてエラーが無いことを確認。
以上です。

mpdサーバ側のfstabの変更
変更点は、rsizeとwsizeの追加ですが、この値については
これから最適値を探していきます。

lsusbのコンパイルをしました。
音が変わったかは、はっきりとはわかりませんでした。
まず、一部、コンパイルのところに間違いがありましたので
修正させて頂きます。
誤 apt-get install build-essential dpkg-dev autoconf automake libboost-dev libicu-dev
正 apt-get install build-essential dpkg-dev autoconf automake libboost-dev libicu-dev meson
・lsusb のコンパイル（mpdサーバ、ファイルサーバ両方に実行）
cd /tmp
apt-get build-dep libusb
wget https://github.com//libusb/libusb/releases/download/v1.0.23/libusb-1.0.23.tar.bz2" target="_blank">https://github.com//libusb/libusb/releases/download/v1.0.23/libusb-1.0.23.tar.bz2
bunzip2 -c libusb-1.0.23.tar.bz2 | tar -xf -
cd libusb-1.0.23
./configure CFLAGS="-O2 -march=native"
make
make install
再起動します。

yoさん、皆さん、こんばんは。
gorokiです。
お久しぶりです。
私は、自身でファイルサーバを構築しているのですが、その設定により
かなり音質に影響が出るようです。
そこで、私の環境において、現時点では、まあ、いい感じではないかと思われる設定内容を公開させて頂きます。
内容の多くは、yoさん、はじめ、いろいろな方のサイトを参考にしています。
/etc/fstab
/etc/sysctl.conf
/etc/rc.local
OSはdebian bullseye リアルタイムカーネル、ファイルサーバはNFS、SSD,2TB 3枚によるRAID0を使用しています。
MPDサーバの設定もraid以外は同じですが、一応、書いておきます。
参考になりましたら幸いです。

# Decoder #####################################################################
#
# This setting sets the address for the daemon to listen on. Careful attention
# should be paid if this is assigned to anything other then the default, any.
# This setting can deny access to control of the daemon. Choose any if you want
# to have mpd listen on every address. Not effective if systemd socket
# activation is in use.
#
# For network
bind_to_address "any"
#
# And for Unix Socket
#bind_to_address "/run/mpd/socket"
bind_to_address "@mpd"
#
# This setting is the TCP port that is desired for the daemon to get assigned
# to.
#
port "6600"
#
# This setting controls the type of information which is logged. Available
# setting arguments are "default", "secure" or "verbose". The "verbose" setting
# argument is recommended for troubleshooting, though can quickly stretch
# available resources on limited hardware storage.
#
log_level "default"
#
# Setting "restore_paused" to "yes" puts MPD into pause mode instead
# of starting playback after startup.
#
#restore_paused "no"
#
# This setting enables MPD to create playlists in a format usable by other
# music players.
#
#save_absolute_paths_in_playlists "no"
#
# This setting defines a list of tag types that will be extracted during the
# audio file discovery process. The complete list of possible values can be
# found in the user manual.
#metadata_to_use "artist,album,title,track,name,genre,date,composer,performer,disc"
#
# This example just enables the "comment" tag without disabling all
# the other supported tags:
#metadata_to_use "+comment"
#
# This setting enables automatic update of MPD's database when files in
# music_directory are changed.
#
#auto_update "yes"
#
# Limit the depth of the directories being watched, 0 means only watch
# the music directory itself. There is no limit by default.
#
#auto_update_depth "3"

###############################################################################
# Symbolic link behavior ######################################################
#
# If this setting is set to "yes", MPD will discover audio files by following
# symbolic links outside of the configured music_directory.
#
#follow_outside_symlinks "yes"
#
# If this setting is set to "yes", MPD will discover audio files by following
# symbolic links inside of the configured music_directory.
#
#follow_inside_symlinks "yes"
#
#
#audio_output {
# type "recorder"

# An example of a pulseaudio output (streaming to a remote pulseaudio server)
# Please see README.Debian if you want mpd to play through the pulseaudio
# daemon started as part of your graphical desktop session!
#
#audio_output {
# type "pulse"
# name "My Pulse Output"
# server "remote_server" # optional
# sink "remote_server_sink" # optional

# Normalization automatic volume adjustments ##################################
#
# This setting specifies the type of ReplayGain to use. This setting can have
# the argument "off", "album", "track" or "auto". "auto" is a special mode that
# chooses between "track" and "album" depending on the current state of
# random playback. If random playback is enabled then "track" mode is used.
# See <http://www.replaygain.org>" target="_blank">http://www.replaygain.org> for more details about ReplayGain.
# This setting is off by default.
#
#replaygain "album"
#
# This setting sets the pre-amp used for files that have ReplayGain tags. By
# default this setting is disabled.
#
#replaygain_preamp "0"
#
# This setting sets the pre-amp used for files that do NOT have ReplayGain tags.
# By default this setting is disabled.
#
#replaygain_missing_preamp "0"
#
# This setting enables or disables ReplayGain limiting.
# MPD calculates actual amplification based on the ReplayGain tags
# and replaygain_preamp / replaygain_missing_preamp setting.
# If replaygain_limit is enabled MPD will never amplify audio signal
# above its original level. If replaygain_limit is disabled such amplification
# might occur. By default this setting is enabled.
#
#replaygain_limit "yes"
#
# This setting enables on-the-fly normalization volume adjustment. This will
# result in the volume of all playing audio to be adjusted so the output has
# equal "loudness". This setting is disabled by default.
#
#volume_normalization "no"
#
###############################################################################

# or /usr/share/doc/mpd/html/user.html
# Files and directories #######################################################
#
# This setting controls the top directory which MPD will search to discover the
# available audio files and add them to the daemon's online database. This
# setting defaults to the XDG directory, otherwise the music directory will be
# be disabled and audio files will only be accepted over ipc socket (using
# file:// protocol) or streaming files over an accepted protocol.
#
music_directory "/var/lib/mpd/music"
#
# This setting sets the MPD internal playlist directory. The purpose of this
# directory is storage for playlists created by MPD. The server will use
# playlist files not created by the server but only if they are in the MPD
# format. This setting defaults to playlist saving being disabled.
#
playlist_directory "/var/lib/mpd/playlists"
#
# This setting sets the location of the MPD database. This file is used to
# load the database at server start up and store the database while the
# server is not up. This setting defaults to disabled which will allow
# MPD to accept files over ipc socket (using file:// protocol) or streaming
# files over an accepted protocol.
#
db_file "/var/lib/mpd/tag_cache"
#
# These settings are the locations for the daemon log files for the daemon.
# These logs are great for troubleshooting, depending on your log_level
# settings.
#
# The special value "syslog" makes MPD use the local syslog daemon. This
# setting defaults to logging to syslog, or to journal if mpd was started as
# a systemd service.
#
log_file "/var/log/mpd/mpd.log"
#
# This setting sets the location of the file which stores the process ID
# for use of mpd --kill and some init scripts. This setting is disabled by
# default and the pid file will not be stored.
#
pid_file "/run/mpd/pid"
#
# This setting sets the location of the file which contains information about
# most variables to get MPD back into the same general shape it was in before
# it was brought down. This setting is disabled by default and the server
# state will be reset on server start up.
#
state_file "/var/lib/mpd/state"
#
# The location of the sticker database. This is a database which
# manages dynamic information attached to songs.
#
sticker_file "/var/lib/mpd/sticker.sql"

###############################################################################
# General music daemon options ################################################
#
# This setting specifies the user that MPD will run as. MPD should never run as
# root and you may use this setting to make MPD change its user ID after
# initialization. This setting is disabled by default and MPD is run as the
# current user.
#
user "mpd"
#
# This setting specifies the group that MPD will run as. If not specified
# primary group of user specified with "user" setting will be used (if set).
# This is useful if MPD needs to be a member of group such as "audio" to
# have permission to use sound card.
#
#group "nogroup"
#
# This setting sets the address for the daemon to listen on. Careful attention
# should be paid if this is assigned to anything other then the default, any.
# This setting can deny access to control of the daemon. Choose any if you want
# to have mpd listen on every address. Not effective if systemd socket
# activation is in use.
#
# For network
bind_to_address "any"
#
# And for Unix Socket
#bind_to_address "/run/mpd/socket"
#bind_to_address "@mpd"
#
# This setting is the TCP port that is desired for the daemon to get assigned
# to.
#
port "6600"
#
# This setting controls the type of information which is logged. Available
# setting arguments are "default", "secure" or "verbose". The "verbose" setting
# argument is recommended for troubleshooting, though can quickly stretch
# available resources on limited hardware storage.
#
log_level "default"
#
# Setting "restore_paused" to "yes" puts MPD into pause mode instead
# of starting playback after startup.
#
#restore_paused "no"
#
# This setting enables MPD to create playlists in a format usable by other
# music players.
#
#save_absolute_paths_in_playlists "no"
#
# This setting defines a list of tag types that will be extracted during the
# audio file discovery process. The complete list of possible values can be
# found in the user manual.
#metadata_to_use "artist,album,title,track,name,genre,date,composer,performer,disc"
#
# This example just enables the "comment" tag without disabling all
# the other supported tags:
#metadata_to_use "+comment"
#
# This setting enables automatic update of MPD's database when files in
# music_directory are changed.
#
#auto_update "yes"
#
# Limit the depth of the directories being watched, 0 means only watch
# the music directory itself. There is no limit by default.
#
#auto_update_depth "3"
#
###############################################################################
# Symbolic link behavior ######################################################
#
# If this setting is set to "yes", MPD will discover audio files by following
# symbolic links outside of the configured music_directory.
#
#follow_outside_symlinks "yes"
#
# If this setting is set to "yes", MPD will discover audio files by following
# symbolic links inside of the configured music_directory.
#
#follow_inside_symlinks "yes"
#
###############################################################################
# Zeroconf / Avahi Service Discovery ##########################################
#
# If this setting is set to "yes", service information will be published with
# Zeroconf / Avahi.
#
#zeroconf_enabled "yes"
#
# The argument to this setting will be the Zeroconf / Avahi unique name for
# this MPD server on the network. %h will be replaced with the hostname.
#
#zeroconf_name "Music Player @ %h"
#
###############################################################################
# Permissions #################################################################
#
# If this setting is set, MPD will require password authorization. The password
# setting can be specified multiple times for different password profiles.
#
#password "password@read,add,control,admin"
#
# This setting specifies the permissions a user has who has not yet logged in.

###############################################################################
# Normalization automatic volume adjustments ##################################
#
# This setting specifies the type of ReplayGain to use. This setting can have
# the argument "off", "album", "track" or "auto". "auto" is a special mode that
# chooses between "track" and "album" depending on the current state of
# random playback. If random playback is enabled then "track" mode is used.
# See <http://www.replaygain.org>" target="_blank">http://www.replaygain.org> for more details about ReplayGain.
# This setting is off by default.
#
#replaygain "album"
#
# This setting sets the pre-amp used for files that have ReplayGain tags. By
# default this setting is disabled.
#
#replaygain_preamp "0"
#
# This setting sets the pre-amp used for files that do NOT have ReplayGain tags.
# By default this setting is disabled.
#
#replaygain_missing_preamp "0"
#
# This setting enables or disables ReplayGain limiting.
# MPD calculates actual amplification based on the ReplayGain tags
# and replaygain_preamp / replaygain_missing_preamp setting.
# If replaygain_limit is enabled MPD will never amplify audio signal
# above its original level. If replaygain_limit is disabled such amplification
# might occur. By default this setting is enabled.
#
#replaygain_limit "yes"
#
# This setting enables on-the-fly normalization volume adjustment. This will
# result in the volume of all playing audio to be adjusted so the output has
# equal "loudness". This setting is disabled by default.

音質については、ファイルサーバの出来によって大きく左右されます。再生システムが大切であることはもちろんですが、上流がしっかりしていることが重要だと思います。その意味において、可能であれば、NASではなく自力でファイルサーバを構築することをお勧めします。また、ネットワークも調整を進めるためにはNFSの方がCIFSより好ましいですね。私としては、部分最適化ではなく全体最適化の視点が重要だと思う次第です。
