[soundnua]: gnome-control-center crashed with SIGSEGV in _IO_vfprintf_internal()

[John Gruber]

Launching sound preferences from the indicator. pavucontrol works fine.

if launched from gnome-control-center the STERR output is:

$ gnome-control-center

Hi,

I have been testing today to try to reproduce this. I have number of duplicates which give roughly the same error, they are all slightly different hence why I have not marked as duplicate but I suspect that a singular fix 'should' resolve them all.

Could you please try something ?

Please modify /usr/share/pulseaudio/alsa-mixer/paths/analog-input.conf
comment out "required = volume" from the [Element Capture] section.

You can comment out with '#'.

Then restart and see if the bug is still present.

thanks,
Conor

I hit this bug by connecting a USB headset and trying to select its microphone as my sound input device in the sound settings dialog. I tried Conor's suggestion in comment #6 and indeed that edit to the config file fixes things for me -- I am able to select the USB headset microphone and sound input does work through that device.

[Roland Dreier (roland.dreier)]

FWIW, my "pactl list" output is the following. The Plantronics device is the USB headset I mentioned.

The bug hasn't seen any activity in years and there has been no recent similar reports, the code also changed quite a lot since and it's likely the issue doesn't exist anymore. Closing, feel free to open a new report if you still get problems in recent Ubuntu versions
