When I start pavucontrol, it opens the GUI and shows some devices then immediately crashes before I can do anything with it. This only happens on my desktop machine (which has 2 audio cards (builtin and PCI) and a USB audio controller attached), not on my laptop.

The only thing shown in the terminal is this:

» pavucontrol
**
ERROR:devicewidget.cc:99:void DeviceWidget::setVolume(const pa_cvolume&, bool): assertion failed: (v.channels == channelMap.channels)
Bail out! ERROR:devicewidget.cc:99:void DeviceWidget::setVolume(const pa_cvolume&, bool): assertion failed: (v.channels == channelMap.channels)
[1]    44400 abort (core dumped)  pavucontrol

I've attached the output of pw-dump (ran right after the crash), and pw-mon (ran during the crash), if you need anything else I'd be glad to help.

pw-dump.log pw-mon.log
