Comment:
Well, fixing one problem sometimes creates another. This is the case here.
After removing all users from the "audio" group, the sound is following
the active console session beautifully. But I am now unable to use my
Logitech usb headset and the microphone on my Logitech usb webcam. This is
sad, because the built-in microphone on my laptop is not very good...
Here is a listing of the /dev/snd directory:

As I understand, the problem is the lack of a + sign after the octals for
the file permissions. Theese device nodes are only present when I plug in
my headset and webcam, and are thus the nodes in use for this hardware,
right?
Now, how do I turn on ACL for devices using usb-snd-audio? I tried to
search the Inernet, but I did not quite know which end to start in ...

I tried reading some of the filesl in /etc/udev/rules.d. I suppose this is
where the solution lies, but udev rules seems to have a steep learning
curve.

PS: I hope you don't mind me reopening the bug all the time.
