Abnormal volume control on latest kernel

jamney · 2024-09-15 03:43:32

After a kernel update, the volume suddenly became too load. I turn it to 0.03 (3%) and its almost like 0.5 before the update. And when I turn it to 0.1 and its like 1. But it wont get much loader. 1 is still like 1. Downgrade to 6.10.9.arch1-2 fix my issue.
I am using System76 laptop peng14. Anyone have similar experience?

good day,

It sounds like the answer I gave here a couple of hours ago to a different question would apply to your problem as well. Try turning the base volume down in alsamixer as described here.

This could be a kernel regression, which should be bisected and reported to the upstream kernel developers (in this case the stable team)

Are you confident to do the bisection on your own or do you need some help?
If you want we could also provide you with pre-built kernel images for you to test

Good info to get you started is:
- https://docs.kernel.org/admin-guide/rep … sions.html
- https://wiki.archlinux.org/title/Kernel … egressions

In order for this to be bisectable properly it would need to be reproducible, but from your description it sounds like it is

Thanks for your reply! I tested some kernel mentioned in https://wiki.archlinux.org/title/Kernel … egressions, and turns out the issue appears after linux-lts-6.6.50-2-x86_64 and linux-6.10.9.arch1-2-x86_64
The issue is also consistent in linux-mainline and the latest upstream kernel
Unfortunately, I am unable to bisect to the exact commit that cause the issue, as my laptop cannot compile the kernel in a reasonable time.

As I already offered I can build you kernel images to test, so if you want we could i.e. bisect between 6.9.9 and 6.9.10.
It would then work out like you can see here for example: https://gitlab.archlinux.org/archlinux/ … ote_196262

Yes please, that seems nice. I would very much like to test in that convenience.
But do I need access to the archlinux gitlab or we can do it somewhere else?

gromit · 2024-09-15 20:32:43

We can do it either here or in the gitlab, IMO the gitlab is the better place though
