lsof is a program that will LiSt Open Files. It will tell you which
programs and PIDs have which files/paths open. Since everything is
pretty much a file, any program using the sound device (for playback,
recording or mixing) will be listed by lsof. Just grep for /dev/snd:

sudo lsof | grep /dev/snd

Using sudo will allow you to see more info.


Another option is to use System/Administration/System Monitor. It can
also list which processes have which files opens. Just launch the system
monitor and go to Monitor/Search for Open Files.
