Bug#703869: audacious: Garbled audio using PulseAudio output on Intel 82801 AC'97

[Ryan J Nicholson]

Thanks Luís.

Adding tsched=0 to the module-udev-detect line in
/etc/pulse/default.paresolves this issue.

I am on Debian 7.1 w/ kernel 3.2.0:

3.2.0-4-686-pae #1 SMP Debian 3.2.46-1 i686 GNU/Linux

I don't have snd_hda_intel loaded:

rjn at lefthand:~$ lsmod | grep snd
snd_intel8x0           22372  2
snd_intel8x0m          17503  0
snd_ac97_codec         84236  2 snd_intel8x0m,snd_intel8x0
snd_pcm                53461  3 snd_ac97_codec,snd_intel8x0m,snd_intel8x0
snd_page_alloc         12867  3 snd_pcm,snd_intel8x0m,snd_intel8x0
