Quite often, and for whatever reason, I go to play a sound in linux and I get a "device or resource busy" error. Restarting alsasound doesn't work. Here's what does:
guttersnipe@guttersnipe ~ $ fuser -v /dev/snd/* USER PID ACCESS COMMAND /dev/snd/controlC0: guttersnipe 21993 F.... python2.5 /dev/snd/pcmC0D0p: guttersnipe 21993 F.... python2.5 /dev/snd/timer: guttersnipe 21993 f.... python2.5 guttersnipe@guttersnipe ~ $ lsof -n | grep "/dev/snd" python2.5 21993 guttersnipe 78r CHR 116,2 0t0 10272 /dev/snd/timer python2.5 21993 guttersnipe 79u CHR 116,4 0t0 10476 /dev/snd/pcmC0D0p python2.5 21993 guttersnipe 80u CHR 116,7 0t0 10466 /dev/snd/controlC0 guttersnipe@guttersnipe ~ $ kill 21993
