• alsa not configured properly

    I am unable to troubleshoot my alsamixer / pulseaudio / snd_hda_intel setup. I get my sound just fine. Great clarity. But if I try to adjust any of the settings, nothing happens. If i open up alsamixer, under card “PulseAudio” there is only one MASTER control that functions. But, if I switch to card “HDA Intel”, there are many volume controls and none of them work. Nothing changes when I adjust them. I tried downloading “gnome-alsamixer” and the same thing. Many volume controls but none do anything. The only thing that has any effect is the “IEC958” button that will turn sound off if I toggle it. I’ve looked through many forum threads, and none seem to match my problem. Everyone has an issue with sound working. Currently I am using my HDMI out to my TV. Sound is perfect. I would like to use my mixing tools though and this has really thrown me for a loop. Here are my stats:

    What am I missing?

  • @ThegoLopez What Desktop do you use, have you installed pavucontrol?

    Are you talking about controlling the volume or about a sound equalizer?

    If volume, have you tried switching off every sound device, which is not used in your Desktops sound configuration?

    I have only one input and one output device enabled, as you can see in the screenshot.

    Both. Being able to control the volume and using the “alsamixer -D equal” command.
