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.

If you are using Ubuntu with the Gnome desktop environment - launch nautilus and navigate to your /var/crash directory and double click on the crash report you wish to submit.
If you are using Kubuntu or Xubuntu you can file the crash using /usr/share/apport/apport-qt --crash-file=/var/crash/_my_crash_report.crash in a terminal - where _my_crash_report.crash is the crash you would like to report.

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.

I'm seeing the exact same problem, but I do not have a /var/crash directory.

If I start the gnome-volume-control from the command line, go to the hardware tab and click the "Test Speakers" button, the app crashes. Every Time.

alord@lobsang:~$ gnome-volume-control
ERROR:gvc-speaker-test.c:390:get_channel_map_for_card: assertion failed: (stream)

(Surely the offending file and line number where the error is happening is enough for a dev to start looking at it?)

lspci -v for my sound h/w is as follows:

00:1b.0 Audio device: Intel Corporation 82801JI (ICH10 Family) HD Audio Controller
        Subsystem: ASRock Incorporation Device 0888
        Flags: bus master, fast devsel, latency 0, IRQ 22
        Memory at f95f8000 (64-bit, non-prefetchable) [size=16K]
        Capabilities: <access denied>
        Kernel driver in use: HDA Intel
        Kernel modules: snd-hda-intel

I'm on an up-to-date Maverick, installed from a daily iso today 09/10/10.

Having just rebooted my PC, GVC is not currently crashing. I will continue to monitor.

Same problem. Was trying to determine why sound stopped working on upgrade to Natty.
All channels open in alsamixer, but crashes on test speakers in gnome-volume-control.

00:1b.0 Audio device: Intel Corporation 82801JD/DO (ICH10 Family) HD Audio Controller (rev 02)
 Subsystem: Dell Device 0276

System has HDMI using:
01:00.1 Audio device: ATI Technologies Inc RV710/730
 Subsystem: Dell Device aa38

But was trying to use the analog sound.

Derek (bugs-m8y) wrote :

In my case, problem went away after killing pulseaudio and restarting it.

Interestingly, while gnome-volume-control showed both audio sources (digital/analog), pavucontrol only listed the HDMI one, and even though gnome-volume-control showed analog as selected, muting the visible HDMI source in pavu, muted the gnome volume.

Killing pulse, and restarting, listed both sources in pavu, and the assertion stopped happening.
