Title:
Bass speakers not enabled on Lenovo Yoga 7 Gen 7 (14ARB7)
Status in pulseaudio package in Ubuntu:
Confirmed
Bug description:
The Lenovo Yoga 7 Gen 7 (14ARB7) has 4 speakers - 2 trebles and 2
basses.
The treble speakers work, but the bass ones don't.
I think this is very similar to
https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1926165,
but that patch does not solve the problem, I suppose because the
chipset is not the same (ALC245 on this machine vs ALC295 on that.
This report has been sent from a system with Pipewire (and kernel
6.0), but this can be ignored, as the problem reproduces the same way
on a system without Pipewire (kernel 6.0 is needed because of keyboard
issues).
