Next to running ps auwx, what other ways can I tell what is using the
sound driver? If I can figure at least that, I can try to disable/remove
it.

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.

It revealed pulseaudio. Once removed, audio capability was restored.

I've seen lsof, but never really used it. Now, I'll remember it!

Thanks!

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.
