Audio works fine for a while until it breaks up randomly and pulseaudio eventually crashes. By looking to the pulseaudio logs one can see some buffer underruns. I also tested with the 3.9.4 mainline kernel though I am not sure this issue is driver related. The result is always the same! I have this in /usr/share/alsa/alsa.conf.d/a52.conf pcm.a52 { @args [CARD] @args.CARD { type string } type rate slave { pcm { type a52 format S16_LE # S16_LE, S16_BE channels 6 # 2, 4, 6 bitrate 640 # 192, 224, 256, 320, 384, 448, 512, 576, 640 card $CARD } rate 48000 # 44100, 48000 } } One other thing I tried was the dcaenc-2 alsa plugin from this web page http://aepatrakov.narod.ru/index/0-2 and this plugin appears to not have the same problem. The disadvantage of the dca plugin is that it needs a lot more processing power! So I would prefer the a52 plugin if it worked flawlessly.
