When I only installed Linux Mint, it worked great. Sound from both - internal speaker and headphones - was completely ok. After some time (and probably my incorrect actions) sound in headphones disappeared. I found out that it was a problem with automatic switching between speaker and headphones - manual switching in Sound Settings fixed that problem.
Of course, it was temporary solution, so a week later I came back to this problem and tried to fix the problem myself... how naive I was. After my "fixes" not only automatic switching stayed broken, but also sound in headphones disappeared completely.
My latest attempts (that actually could break sound settings) are:
1. In file "/usr/share/pulseaudio/alsa-mixer/paths/analog-output-headphones.conf" changing [Speaker Element]
[Element Speaker]
switch = on
volume = ignore
(solution found on StackExchange, doesn't work, reverted to "off" for both params)
2. In file "/etc/modprobe.d/alsa-base.conf" adding line:
options snd-hda-intel model=<config-option>
with <config-option> set to "basic", "generic", "hp-laptop", "m51va position_fix=0", "3stack-dig position_fix=0". Nothing changed - neither headphones started to work, nor speaker stopped.
3. Playing around with alsamixer. Right now:
Master: active
Headphones: active
Speaker: muted
PCM (don't know what it is): max volume
Mic: muted
Mic boos: zero volume
S/PDF: active
Auto-mute: enabled
Internal: muted
Internal (another bar): 20%
Headphones plugged-in, but no sound.
Some system info is below, if you need something else, just let me know.
