    I found a solution here: https://wiki.debianforum.de/Audiokonfiguration

    I have created a “.asoundrc” in the root of my home.

    defaults.pcm.!card 0
    defaults.pcm.!device 8

    After reboot i can use alsamixer with the output “pre-Amp”. On “Open-Mixer” you can change the Channel to “PRE-AMP”.


    i would try running alsamixer in terminal:

    first check to see if any outputs are muted;
    then press F6 to pick the right sound card;
    then esc out of alsamixer.
    save setting by sudo alsactl store. might have to reboot.


    Martin’s answer is correct. Sometimes alsamixer and sound card selector do not pick the correct device, and one needs to create a file .asoundrc in home or editing the one in /etc.
    But kksmith is also right (to first test if the channel is muted).

    There are a few problems in the forum that could only be solved using Martin’s advice.
