Public bug reported:
Binary package hint: gnome-system-tools
Just today I upgraded from 9.04 to 9.10. After the upgrade, I could no
longer play sound. Some debugging showed that the problem was quite
simple: I was no longer in the "audio" group, so all the device files
under /dev/snd/ were inaccessible to me. Hence "aplay -l" returned "no
soundcards found". I opened users-admin and found that many of my
Permissions had been mysteriously revoked! "Use audio devices" was only
one of them. I had also lost the ability to use video devices, and
several other things that I don't recall. After re-enabling those
permissions, audio started working again. However, users-admin also
shows that I am "Not authorized to make changes" at the bottom, even
though I have the "Administer the system" permission, so I can only
administer the user settings by manually sudo'ing the users-admin tool.
Note that I have another user account on this machine which did NOT lose
permissions. In case it matters, the one that lost permissions is the
same one that I was using when I did the upgrade.
Expected: Users should have the same permissions after Karmic upgrade,
and the users-admin tool should allow me to make changes.
