  • Unmuting outputs:

    Terminal window
    alsamixer

  • Testing speaker channels:

    Terminal window
    speaker-test -c 5 -D default -t wav

  • Disabling automatic suspension of sink in Pulseaudio:

    Terminal window
    sudo vi /etc/pulse/default.pa

    Comment this line out:

    # load-module module-suspend-on-idle

    Then restart Pulseaudio (probably easiest by logging out and in to X again?)
