Title:
Extreme low audio when using headphones
Status in alsa-driver package in Ubuntu:
New
Bug description:
The laptop audio works fine, but when I plug a headphone it seems that
there is no audio. If I turn on overamplification it is possible to
hear some low volume sound. So, the audio is actually there, it is
just extremely low.
I tried multiple things that I found only but none seems to work.
