Bug#646682: bad crackling audio

[Juhani Karlsson]

Hi

After reboot I noticed this in logs and bad crackling audio with also 
other programs like Kaffeine.

No matter which settings I used in pulseaudio volume manager, also with
Active profile: output:analog-surround-51+input:analog-stereo

alsa force-reaload and /etc/init.d/pulseaudio restart, no help.
reboot again fixed problem

on luultavasti ohjelmavirhe ALSA-ajurissa ???snd_emu10k1???. Raportoi 
t??st??
ongelmasta ALSA-kehitt??jille. Taustaprosessi her??tettiin POLLOUT 
asetettuna,  snd_pcm_avail() palautti kuitenkin 0 tai jonkin muun arvon, 
joka on <
min_avail.
