[LAU] laptop confused: no sound with headphones in

Hi I have a laptop running debian 10. Sometimes it gets confused with a mini-jack in headphones and mutes audio. It seems to be something automatic that goes wrong, since 1) pulling the mini-jack makes the sound come out of the speakers just fine (putting it back in mutes audio again etc)and 2) a reboot fixes it. I tried writing a script that un-mutes everything I can see and turns it up, but to no avail: amixer set 'Master' 100% unmute amixer sset -c 0 'Master' 100% unmute amixer sset -c 0 'Headphone' 100% unmute amixer set -c 0 'Speaker' 100% unmute amixer set -c 0 'PCM' 100% I'd like to know what's causing this and most importantly: any solution or work-around would be great! I know it's a long shot, but maybe someone can recognize this and point me in a more constructive direction? Cheers -- Atte http://latestyoutube.a773.dk | http://a773.dk
