[] pulse audio raop設定 / alsa設定

http://raspberrypi.stackexchange.com/questions/5508/redirect-audio-to-another-airplay-device

にしたがってできたはずなんだけど、rebootしたら動かなくなってた...。

まずはpulse audioからraopで音を飛ばすところを確認する。

$ pulseaudio --log-level=debug -vvvv

  • 立て続けでやると、二回目以降が何故かlink localのもので解決されるというのが問題らしい。
  • しょうがないからlink localのアドレスも割り振る。
    • force-bindはつけないと、普通のdefault routeあるせいか有効にならない。

これやったけど、結局音出ない。

そもそもalsaで音出すのがまともに上手く行っていない。

$ echo "play-file /usr/share/sounds/alsa/Front_Center.wav 0"|pacmd

一応たまに音が出る。なんだこの糞は。
