How to Kill a previous Audio process?
I obtain this error: audio_alsa_sink[hw:0,0]: Device or resource busy
And I remember there is a command to do it… but I don’t know which!

There are to possibilities in this case:
Either, you can live with a small added latency due to software mixing,
then
you should use “default:0” instead of “hw:0” (given that your
distribution
configures ALSA to use software mixing, which is the case for all major
distributions), or you really want to access the device exclusively.
In
this case, use fuser:

list programms accessing any pcm device:
fuser -v /dev/snd/pcmC?D?
kill any programm accessing any pcm device:
fuser -k /dev/snd/pcmC?D?
