Are you logged in as Guest? There are a lot of "Permission denied" errors in the information sent by Apport, sometimes even when trying to access information that's available even to limited users (but not necessarily available to Guest). And the error from when Apport tried to run fuser with pkexec (to report Symptom_DevicesInUse) is quite unusual, but I am able to produce this exact error by attempting to run a command-line program with pkexec from a Guest session.
If you were logged in as Guest when you reported this bug, is that because sounds is only broken when you log in as Guest? Does sound work when you log in as a "real" user? If the problem affects the Guest account and other accounts equally, I recommend logging in with a normal user account and running "apport-collect 1078993" (without the quotes) to add information to this bug. Alternatively, you could re-report the bug while logged in as a normal user, then make this bug a duplicate of the new one. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1078993 Title: [System Product Name, ATI RS880 HDMI, audio (Radeon HD 4200) No sound at all To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1078993/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
