I am deaf in one ear and want Ubuntu to mix both left and right audio channels to mono audio. There is an Accessibility Setting for this in Windows, but I cannot find one in Ubuntu. The only Hearing Accessibility Setting I can find is for Visual Alerts. I am currently using 21.10, but also couldn't didn't see anything on my other computer running 20.04 LTS.

I saw a couple of older search results for mono audio in individual programs, but would prefer a solution that handles audio for the entire OS.

Thanks for any help.

If the pacmd command works from the other answer:

pacmd load-module module-remap-sink sink_name=mono master=alsa_output.pci-0000_00_1f.3.analog-stereo channels=2 channel_map=mono,mono

you can add the command to start at boot time.

First, search your applications for "startup applications". Open the Startup Applications app and then click Add.

Next, a popup window will appear.

  • For the Name, enter "mono"
  • For the Command, paste the pacmd command you used earlier.

Finally, click Add.
