Debian Squeeze Notes


If the sound disappears from browsers etc. and you get something like:

ALSA lib pcm_dmix.c:1018:(snd_pcm_dmix_open) unable to open slave
Playback open error: -16,Device or resource busy

try to find and kill pulseaudio processes:

lsof|grep snd
pulseaudi 18515       pink  mem       CHR      116,3                4059 /dev/snd/pcmC0D0p
kill 18515

and restart browsers.
