Sound settings crash with USB sound device

[Andy Gittings]

Description: Ubuntu 12.10
Release: 12.10

Upon clicking Sound within System Settings a crash occurs if the USB sound device is connected. If the USB sound device is removed the sound settings window can be opened.

Error from dmesg:

gnome-control-c[12323]: segfault at 7fff19d1ceb8 ip 00007fa952cc19f2 sp 00007fff19d1cd80 error 6 in libc-2.15.so[7fa952c79000+1b5000]

This results in the settings for this device not be available for editing.

USB audio device is a PCM2902 Audio CODEC

As a workaround I have installed the "pavucontrol" package - and this allows the device to be configured.

 Thank you for taking the time to report this bug and helping to make Ubuntu better. However, your crash report is either missing or challenging to deal with as a ".crash" file. Please follow these instructions to have apport report a new bug about your crash that can be dealt with by the automatic retracer.

If you are running the Ubuntu Stable Release you might need to enable apport in /etc/default/apport and restart.

Now open your file manager, navigate to your /var/crash directory and open the crash report you wish to submit.
If this fails you will have to open a terminal and file your report with 'ubuntu-bug /var/crash/_my_crash_report.crash' where _my_crash_report.crash is the crash you would like to report. If you get an error that you aren't allowed to access this report you will have to file it with 'sudo ubuntu-bug /var/crash/_my_crash_report.crash'.

I'm closing this bug report since the process outlined above will automatically open a new bug report which can then dealt with more efficiently. Thanks in advance for your cooperation and understanding.

No offense, but this is ridiculous. You cannot close a bug saying RTFM and come back later! And you have all the info you need: start up Ubuntu, plug in any USB sound card and, presto, there's your bug. I would have attached a crash file myself but it is not generated. The sound settings dialog just disappears. without a trace.

[Jayes (web-zwnfzp)]

Yes! I managed to get a crash report after reinstalling apport.

 And guess what?.....

Sebastien,

I just stumbled upon Bug #1067700. Exacly the same bug. And on 2012-12-13 you closed that one too, for the same reason. Aren you trying to ignore this bug to death? Or the people that took the trouble reporting it?

same error trying to select x-fi usb hd as audio input in control center

[Rüdiger Kupper (ruediger.kupper)]

Same problem here with the "PCM2902 Audio CODEC" USB device.
And yes, this looks like a duplicate of Bug #1067700. Please confirm and close one of them as a duplicate.
I will attach the output of "gnome-control-center sound -v".
