I'm running on Ubuntu 20.04, on a Dell XPS 13.
Every time I plug in my headphones, all sound is muted.
Following instructions in other posts here, I do alsactl restore
, which enables both my headphones and my built-in laptop speakers. I then have to go to alsamixer
to manually switch off my speakers, so that I can actually get sound out of my headphones, and exclusively out of my headphones. One would expect this would happen automatically when you plug in your headphones.
As mentioned, the other posts here explain how to solve this manually by doing the above every time you plug in your headphones. For that reason I don't believe this post is a duplicate. Many users would like to know how to solve this problem permanently.
How do we permanently fix the above issue?
sudo dmidecode -s system-product-name
I sporadically had to run alsactrl restore on a 9350, but I never have the issue anymore on a 7390. – vanadium Jul 07 '20 at 09:55
