Hopefully I am not asking a duplicate question, but all the answers I found so far did not help me. Alsamixer channel is not muted and when I switch to headphone output via pulseaudio there is still no sound, however internal speakers are muted.
Here the output of pulseaudio --dumb-conf:

Please let me know if you need any other information that I can provide - thanks in advance.
EDIT: I found another surprising behavior, that might be related with my problem. When I have no headphones plugged in and use alsamixer to mute the headphones channel, then Master, Headphones and Speaker Channel becomes muted.
