Comment # 7 on bug 1207129 from Alexander Osthof

OK, I've tried the KMP but unfortunately without good results. Although the
devices show up correctly they don't really work:

- When turning the volume wheel on the headset itself the display shows jumps
from e.g. 100% to 45% to 0% although I'd expect it to be 5% steps
- During the one time I managed to get sound output on the headphones to work
the volume was very low although it was at 100%
- I didn't manage to get the mic to work at all

All the above was done using the USB connection with the dongle as here in the
office I don't have BT. I've meanwhile switched to pipewire on Leap 15.4.

Please let me know if I can/should run any further tests or provide any
debugging information. In any case, thanks a lot for investigating this issue.
