BBBでvolumioを試し、一応音を鳴らす事ができたので記録に残すこととする。
使用したのはAKI.DAC-U2704と自作PCM5122 I2S I/F DACの二種類。
PCM5122 I2S I/F DACに関しては以下を参照。
■202 BeagleBone BlackでPCM5122 DACを鳴らす(その１)
volumioとは以下のサイトで開発配布されているdebianベースの音楽再生環境でBBB向け環境も用意されている。
https://volumio.org/
BBB用の現時点での最新版は1.5で私は以下から”Volumio1.5BBB.img.zip”を母艦（ゲストOS）にダウンロードした。
https://volumio.org/get-started
zipファイルをunzipすると起動用1SDカードイメージバイナリ”Volumio1.5BBB.img”が取得できるのでそれを適当なSDカードに焼き込む。
以下は母艦(ゲストOS)で/dev/sdbとして認識されている前提。
temp-host@temp-host:~$ sudo dd if=Volumio1.5BBB.img of=/dev/sdb
すごく時間がかかる。
完了後、syncを行いmicro SDカードを取り外す。
temp-host@temp-host:~/download$ sudo sync temp-host@temp-host:~/download$ sudo sync temp-host@temp-host:~/download$ sudo sync temp-host@temp-host:~/download$ sudo reboot
micro SDカードをBBBに挿入し、シリアル接続とETHERNET接続を行い電源投入を行う。
ここで注意点として初回接続する場合、ETHERNET接続は必須であり、シリアル接続はあった方が良い。
ここの記載ではLAN上のPC/スマホのWEBブラウザから http://volumio.local にアクセスすると WEB UI画面を開く事ができる事になっているが、自分の環境では名前解決できず接続できなかった。
シリアルコンソールのログ上にeth0にETHERNET経由DHCP割り振られたIPアドレスが残るので、LAN上の母艦から http://192.168.1.28 にアクセスすると 無事WEB UI画面を開く事ができた。
以下USB TTLシリアルでの起動ログ。
少し長いが引用する。
設定は115200bps 8bit; non parity; stop bit 1; フロー制御なし。

見ての通り、いくつかのfailやwarningが出ている。
この例では192.168.1.28のIPv4アドレスがDHCPにより割り当てられた事が判る。
シリアルコンソールで接続しないならば、ルータ側から割り当てIPを調べるか、もしくはBBBのeth0のMACアドレスに固定のIPアドレスを割り振る等の工夫をするべきだろう。
特記事項としてはシリアル経由でログインできない事。
代わりに割り当てIPアドレスで以下のuser/passwdでsshログインすることができる。

WEB UIの起動画面は以下のようになる。
右上にあるMENUの文字をクリックすると”Main”, “Library”, “Playback”, “Network”, “System”, “Credits”, “Turn off”の項目を選択できる。
判り難い事に、DACを認識していない状態ではI2Sの設定がどこにも出てこない。
volumioのサイトではBBB用Ver1.5でI2Sサポートとなっているが、実際にはサポートされていないのかなと思い、AKI.DAC-U2704を試すため、 一旦turn offからPower offを選び電源断を行い、AKI.DAC-U2704をBBBに接続し、色々設定を弄っていたらSystemメニュー(Setting)の中にI2S driverが 出てくるようになった。
その後はAKI.DAC-U2704を外してもI2S driverの項目は消えないようだ。
どのようにしたらI2S driverの設定が現れたのか良く判っていない。
AKI.DAC-U2704の方の設定は、MENUから”Playback”を選択し、”Audio Output”の選択肢が”Black”となっているのを”DAC”に変更する。
Reboot後に有効となる。
DACが有効となっていれば、起動完了時にチャイムが鳴ることが判る。
volumioはウエブラジオが聴けるので曲を用意しなくてもDACの確認は可能。
下の帯の左側にある”Brows”をクリックしすると”WEBRADIO”が出てくるので選択し、適当に局を選択し局名の右側にある三本の太い線の マークをクリックすると”Add”, “Add and play”, “Add, replace and play”, “Update this folder”の選択肢が出てくるので “Add and play”をクリックすると聴くことができる。
ただし、その前にMain画面で右側にある円を回すことにより音量を75以下に下げておいた方が良い。
音量が大きいので耳を傷めるからだ。
次に自作PCM5122 I2S I/F DACを試す。
I2S DACの場合はMENUの”Playback”の”Audio Output”の選択肢を”Black”に戻す。
そしてMENUの”System”の”I2S driver”のなかから適当にdriverを選択する。
自分はRPi-DACのみ試していて他は試していない。
“APPLY”をクリックし設定を完了させ、MENUの”Turn off”から”Power off”を選択し電源を落とす。
どうも”Power off”としても再起動してしまう事が多い。
BBBとDACとの接続は以下の通り。
I2S_LRCK:P9_29 I2S_DIN:P9_28 I2S_BCK:P9_31 I2S_SCK:P9_25 I2C_SCK:P9_18 I2C_SDA:P9_17 SYS_5V(CP):P9_7 SYS_5V(A):P9_8 VDD3.3(D):P9_3 GND(CP):P9_1 GND(A):P9_45 GND(D):P9_2
前に書いた記録に対し、I2S_DINの結線が変更になっている事に注意。
また、I2C_SCKとI2C_SDAは使用しないのでDVDDにプルアップした方が良いかもしれないがとりあえず放置する。
起動完了時にチャイムが鳴る。
AKI.DAC-U2704の時とは違い、音量はそれほど大きくはないが、それでも耳障りなほど音が大きいうえに激しい プチプチノイズが乗っている。
プチプチノイズは音量を75程度まで下げると発生しなくなるので、音量がデジタル的に飽和しているのかもしれない。
だが、デジタル的に音が飽和したからといってプチプチノイズになるかは疑問だ。
44.1KHz音源の48KHzへのリサンプリングにCPUパワーを取られすぎて処理落ちしている可能性もある。
topコマンドで調べるとmpdが常時50数%使っているようだ。
プチプチノイズの理由は調べておらず、ひょっとして自分の環境だけかもしれない。
AKI.DAC-U2704の方にプチプチノイズが乗っていたかは憶えていない。
ちなみにAKI.DAC-U2704も自作PCM5122 I2S I/F DACもDACからの出力を直接ヘッドホンで聴いている構成でヘッドホンアンプは使用していない。
まあ、何れにしても音量を75まで下げると問題は発生しなくなるのでこんなもんだと納得することにする。
WiFiの設定は通常ならばMENUの”Network”の”Wireless Connection”で行えるらしい。
しかし自分の環境ではルータの設定のため、以下以下で記載したように追加設定が 必要であるので手動で設定した。
一応設定ファイルは以下のような感じとしている。
root@volumio:~# nano /etc/network/interfaces root@volumio:~# cat /etc/network/interfaces auto lo iface lo inet loopback auto wlan0 iface wlan0 inet dhcp wpa-ap-scan 1 wpa-scan-ssid 1 wpa-bssid 10:6F:3F:4B:20:55 wpa-key-mgmt WPA-PSK wpa-proto RSN wpa-pariwise COMP TKIP wpa-group CCMP TKIP wpa-ssid MY-AP-001 wpa-psk hogehoge auto eth0 iface eth0 inet dhcp root@volumio:~#
これでWiFi接続でvolumioにアクセスできるようになった。
AndroidスマホからでもLAN内からIPアドレス直打ちでアクセスできるので凄く便利だ。
volumioはとても便利で面白い。
また、WEBRADIOを長時間聞いたが楽しいものであった。
今回の環境はmicro SDの使いまわしの為に消してしまうが、別のもっと高速なmicro SDを買ってきて ちゃんと設定を行っても良いかなと思ている。
