shows which process is using another process in form of a tree scheme.
If there will be an application using OSS or ALSA etc. this is shown.
I know this myself just for some hours, before I only knew about ps aux,
but it isn't a help, because we can't know all applications, that might
have to do with OSS and ALSA or any other sound server.
Force the appearance of the problem by removing "killall esd &" and run
pstree, resp. oops, I'm wrong, I can't see ALSA with pstree. Does
someone know a way to see which application will use another application
by showing it complete?

There might be something wrong, I had to reboot, because my soundcard
wasn't shown in Jack and after reboot it has been fine again. No,
everything seems to be fine, there's nothing wrong with ALSA, the
messages from Jack are fine. pstree won't work the way I hope it would.
Hmm. Sorry, I don't know a command that will help you.
