Version 2.
User 1 logs in, uses xmms, logs into a couple of consoles (use
bittorrent, do an update and something else). Logs out
User 2 logs in, xmms reports soundcard blocked.
What should happen is for version 1, user 2 should gain control over the
soundcard.
Absolutely. If User 2 doesn't gain control that's a bug. Can you be
sure that /var/run/console/console.lock doesn't exist after User 1 logs
out?
Not sure what should happen for version 2, but I think once
user 1 has logged out of the X session, then user 2 should gain
permission.
Yes, I think it would be best if user 2 gained permission as well, but
unless the device supports hardware mixing you're going to lose anyways.
In this case you need a sound server. But if you do have hardware
mixing one nicer way to do this might be to modify pam_console to use
ACLs on the devices instead of changing ownership.
