Segmentation fault when using alsamixer to display a sof-soundwire card

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



alsa-project/alsa-utils issue #100 was opened from Aetf:

The builtin soundcard on my XPS 9700 recently stopped working. I tried to use alsamixer to see what's going on, and it gives me a segmentation fault.

The program works segfaults as soon as I choose `sof-soundwire` as the sound card by pressing F6. But as long as I don't choose that, it works fine with other cards.

There's the backtrace:
```
