I'm using a 2.1 speakers kit from Logitec but most of the time it is always detected as 2.0... 😒
So I decided to make some research and found a solution that works everytimes (on Ubuntu based distribs).
It seems to work also on Arch Linux, see comment from @ilikenwf.
As you can see, my audio output is not patched.
To fix the problem easily, I wrote a small script to run as root or using sudo
.
sudo bash pulse-audio-2.1-patch.sh
You will need to reboot to apply the changes.
Now you can see the result of the patch, for the best result, set your principal audio output volume close to the max then select the new audio output entry as shown below and set the volume you want. 😁
Now you can enjoy a much better and cleaner audio output. 😉 🤘

This worked for me on Arch also. Thanks!
