Method to force mono audio?

Hi all,

I managed to sort out my dualboot from my previous post now i’m onto my next issue that’s made me stuck. I like to sometimes use only one cup on my headphones and for that reason i was looking for a way to force mono audio instead of stereo, so i can hear all the audio in one ear. Is there some sort of config i can change?

Thanks in advance :slight_smile:

To remap stereo audio to mono in PulseAudio

  1. Get the name of the default sink used for audio playback

    pactl get-default-sink
  2. Create a file in user home folder for custom PulseAudio configuration with a text editor

    sudo nano ~/.config/pulse/
  3. Copy & paste this text into text editor

    .include /etc/pulse/
    # Remap stereo to mono
    load-module module-remap-sink master=[default-sink] sink_name=mono sink_properties="device.description='Mono'" channels=2 channel_map=mono,mono
    # Optional: Select new remap as default
    set-default-sink mono

    Replace [default-sink] with name of default-sink from 1.

  4. Save configuration file Ctrl + O and quit nano Ctrl + X

  5. Restart Pulseaudio:

    systemctl --user restart pulseaudio
