Method to force mono audio?

[projec3t]

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

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/default.pa
   

3. Copy & paste this text into text editor

   .include /etc/pulse/default.pa
   
   # 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
