Bass speakers not working properly - Lenovo Yoga Pro 9

Support Sound
1

Manjaro cinnamon on Lenovo Yoga Pro 9 16IMH9.

The laptop has at least 4 speakers, 2 bass “subwoofers” and 2 treble “tweeters”. The problem is that shortly after login, bass speakers stop working, resulting in tinny and barely audible sound.

Similar problems have been reported, both here and there in this forum and elsewhere on the internet.

EDIT: The solution given in comment #15 at this bug report seemed to fix the issue, however after the latest upgrade to 6.12.17-1-MANJARO and Cinnamon 6.4.8, the problem returned.

After further events, it seems the fix is still working, except after rebooting.

On proper shutdown and restart, sound works as expected, but after rebooting (choosing “restart” from the menu), the problem returns. Either with the bass speakers disconnected at login, or disconnecting a few minutes after login.

Very confusing.

You may want to look through this tutorial, may or may not help.

Thanks for the pointer, though it doesn’t really adress my problem (bass speakers disconnecting). However, the guide looks interesting, and I’ll likely try it out when the issue with the bass speakers is sorted out.

Edit:

The issue remains the same. After “cold starting” the laptop, sound initially works as expected but after a while, the bass speakers stop working.

I have not been able to determine if any particular event precedes the issue - sometimes I can use the machine for hours with sound, at other times they stop working after a few minutes.

You might try to be a bit more aggressive;
