• Alsa + CMI8768, master loudness has no effect


    Hi,

    adjusting the sound settings to only work with 2.0 Sound of my PCI card with a CMI8768 chip was a piece of cake. Controlling the master volume works out of the box, therefore keyboard buttons are usable, too.

    However, when I switch to 5.1 Output, I can’t adjust the master volume for all other speakers except for FL and FR. Even setting the master to 0 has no effect on Center, RL, RR and SW, which continue at full volume (estimated). I can control the volume through alsamixer, adjusting the PCM volume and keeping master volume at 100%.

    I don’t think that this is intended to work like that, also because I can’t use my keyboard buttons with it. Furthermore I’m not sure if the PCM settings are remembered across reboots.

    (This is probably not specific to Antergos as I had the same issues with Manjaro and would probably also have it with every other Linux distro, I just didn’t know where to ask for advice.)

    So, how do I fix the master volume to also influence Center, RL, RR and SW?

  • Hi,

    Are you using pulseaudio or jack?

    I have no experience with sound, just trying to help…

  • I’m not sure if that’s the way to check for it, but alsamixer says I’m using pulseaudio as device.
