I am currently having a problem with the audio on my laptop. Specifically, I am only getting audio from the left channel whilst using my wired headphones. I tried these headphones with a micro Hi-Fi system (remember those ?!) where I was able to experience output on both channels/'phones.

I installed pavucontrol, found that it did not help and so uninstalled it. I then manually installed pipewire and pipewire-tests. These have not helped either. Is there another "part" of pipewire that I should install ?

Re System Settings/Hardware/Audio: When I click the (headphones) Test button and then click front-right, a new setting temporarily appears behind the "Built-in Audio Analog Stereo" window. This setting is labelled "libcanberra:front-right". However, no sound comes out of the right channel/'phone.

Is there something else, perhaps some kind of mixer, that I should install ?

Hi. Have you tried using amixer in the terminal?

I've also managed to find myself in this situation.

Running amixer by itself will give you a printout of the settings that you can share here.

There are also some commands you could try.

Code: Select all

amixer -c 0 sset Master 80%,80% unmute

I am not always sure with commands with these, so Master may need to be swapped out for something else.

Hi,

@bbbhltz: Thank you for your reply. Running amixer as you suggested showed the following:

Code: Select all

$ amixer -c 0 sset Master 80%,80% unmute
Simple mixer control 'Master',0
  Capabilities: pvolume pvolume-joined pswitch pswitch-joined
  Playback channels: Mono
  Limits: Playback 0 - 87
  Mono: Playback 70 [80%] [-12.75dB] [on]

I see that the playback channels are set to Mono. How do I set them to stereo ?
