After installing those debug packages, the crash report gdb instance
crashes, so instead here is the initial crash file and a basic run of
gdb. If you would like me to add any commands to gdb, let me know what
those are.
I've found a shorter reproduction that actually causes the sound
properties to hang rather than sigterm.
1. Open Sound Properties.
2. Test second "VIA 8237" Sound Capture device.
3. Select first "VIA 8237" device (don't run test).
4. Select second "VIA 8237" device again.
The program instantly hangs the instant I re-select the second device
and must be killed since it doesn't crash.
Here is the debug output in which I followed the other reproduction
steps where I test both devices:
