No sound for apps on ubuntu machine

0 votes
41 views

Yesterday, all application sounds for one of my user account stopped. I still get the startup sound for that account and on the other user accounts the sound works OK. It's obvious that it's not the hardware.

I am using the Mint desktop. I checked to see if the sound volume was turned down and it is at 100%. I also checked to see if the sound was muted, it's not muted. I checked under system /preferences / sound and everything seems to be OK. When I tested the speakers using the sound utility I do get sounds. Since I get the startup sound, the speakers work when tested (using the affected user account, and the other user accounts work fine.

Only the applications (Firefox, VLC, etc.) seem affected. I checked the applications but I doubt it is an application setting because all applications are affected. Any suggestions on where else to look?

Check you still have the correct output device selected in sound settings, I managed to change mine somehow once and it confused me for a few hours!! Gotta be worth a look!

If you open pavucontrol you can watch what sound output is being used at the time. If it is not correct, then switch the output to whatever device you chose. Hope this helps.

We have changed disks recently. Using 2 different disks for storage and backups - a USB to back up a local non-boot disk - all disks ext4.

Both disks have a 'lost+found' folder, root permissions with Ubuntu 12.04. Properties for both disks say 'some contents unreadable'. I'm assuming that's because of the 'lost+found' folder, but please tell me if there's more to it...

In grsync, I have 'delete on destination' checked. When I backup the local disk to USB, it does copy newer files, but does not delete older files. At the start of the progress window it says 'permission denied' for the 'lost+found' folder. Next line: 'IO error - skipping file deletion'. And indeed it does no deletions for any file.

How can I get it to delete files that are no longer on the source/local disk?

Also, I recently copied the old local disk [1G] to the new 2G local disk mentioned above - I was running out of space. Is it possible that this copy did NOT copy all the files? I just assumed it would and didn't check.

I am using Ubuntu 14.04 and facing problem with ubuntu? On my machine Skype starts, asks to log in and then presents its list of connections. However after a couple of moments the list of connections gets
"inactive" (greys out) and finally disappears.

In the crash window that then pops up I see that something with libc.so.6 seems to be amiss.

Any idea what I can do to fix the problem and where do I find the info that is in the "crash report window" so I
could add it to this email if needed?

I've discovered in syslog that postfix is reporting

postfix/cleanup[31051]: warning: mail_queue_enter: create file incoming/407669.31051: No space left on device

I also have problems with boinc suddenly stopping, apparently because it loses its connection to localhost. I don't know if this is connected.

df reports that all disks have plenty of space (root is only 40% used), no swap is being used, the waste bin is empty, and disks appear to be healthy. Any suggestions as to what might be causing this?

I'm using 14.10, with 3.16.0-25-generic.

The bond is created but the MII status is down.
The error is:

Does anyone have idea about this problem?
