Today suddenly my headphones stopped working. it was surprise because everything was working perfectly. After doing a lot of things with my Laptop, following command worked -
alsactl restore -P
Now the sound is coming from both Laptop speakers and Headphone, I did some setting to mute my speaker using “alsamixer”, yeah I put my speaker on mute. Auto mute option is enabled already, but seems not to working.
Now on boot the settings are restored and every time I need to set alsamixer to put my speaker on mute.
any clue how to resolve this issue ?
