Title:
[Precision 5540, Realtek ALC3266, Black Headphone Out, Left] No
playback when selecting "Headset" after headset connection
Status in alsa-driver package in Ubuntu:
Confirmed
Bug description:
Just upgraded to ubuntu 20, worked fine with 18.
When I plug in my hyperX headset, the sound does not work when I select
Headset, even if I change back and forth with the speakers in the settings.
It works perfectly if I select Headphones, and I can then select my headset
microphone as a workaround.
Thanks for the great work!
