Debian no sound after clicked I don't know what in alsa mixer.
 

Hi there. I have Debian installed. I wanted to adjust alsa mixer sound volume. I do not know what I clicked there and I have no more sound. Even if I adjust Master, or anything I change in the mixer I have no more sound. Can you help me please to restore anything of that to factory defaults or help me get the sound back?

Hello and welcome to the forum :)

Sure. Could you post a screenshot (or a link to one) of the results of alsamixer in your next post? Most likely you muted the Master channel or some other entry. This will be indicated by "MM" on the bottom of an individual "bar" or channel. Take a look here for additional help.

Regards...

Have you checked that the outputs are not muted? Every output slider has a speaker icon below it; it shouldn't be disabled.
