Volume always maxed on Lenovo Yoga Pro 7 on EOS KDE Plasma [looking for help]

General system Gaming, sound and video
1

Hey all,

I am fairly new to Linux in general so please do not be too harsh with me.

I am experiencing a weird issue and could not get further on my own. There are some threads here and there with a similiar issue, but they did not provide anything that worked for me. I installed EOS on my Lenovo Yoga Pro 7 and since the beginning I cannot control the volume globally. I can of course control the volume within any app (if they provide a way) but in the actual volume control of the system I have either zero or maximum volume (considering the outcome, virtually I can control the volume in small steps, but it does not work; the slider shows to be at x% but the actual volume is constantly at maximum.

inxi -A gives this output:

Audio:
Device-1: Intel Meteor Lake-P HD Audio driver: sof-audio-pci-intel-mtl
API: ALSA v: k6.17.7-arch1-1 status: kernel-api
Server-1: PipeWire v: 1.4.9 status: active

Any ideas? Thank you!

EDIT: I forgot to mention: The Laptop had Windows preinstalled and the volume worked fine, so it should not be a hardware problem.

Welcome to the forum.

You never mentioned a DE which may be irrelevant. You are at the Master Volume of your DE’s system settings?

You slide it to something less ear-splitting and says ‘screw that’ and jumps back to 100% with its middle finger out in the system settings?

that’s trippy.

If you have WIN on half this disk that’s the first thing I’d blame. if you don’t great.

Spitballin:

Lenovo bundled software fubar?

two sound .services enabled in systemctl?

are there pipewire setting independent of system settings?

I coudn’t see anything fishy in the output. But a sound expert I am not.

Conversely in Cinnamon I’ve always left it alone and adjust thru the app:

cin
cin775×496 26.6 KB

the more I think about that’s the way I’ve always done it as far as what you call ‘globally;

–the difference being if you move it to 50% it moves itself back. A mystery. hang in there, someone will know

As said in the title (it is a bit hidden) I use KDE Plasma. To clear things up:

You are at the Master Volume of your DE’s system settings?

The master volume of KDE Plasma was what I meant by “global volume”

You slide it to something less ear-splitting and says ‘screw that’ and jumps back to 100% with its middle finger out in the system settings?

No, it keeps the value in terms of what it displays, but it outputs max volume all the same.

If you have WIN on half this disk that’s the first thing I’d blame. if you don’t great.

I don’t, I bulldozed the disk before installing EOS.

Lenovo bundled software fubar?

Can they bundle stuff if I install a custom OS? You mean bundled with EOS? Never heard of such thing before.

two sound .services enabled in systemctl?

Since the inxi -A Output only shows one I suppose there is not? Is there another way to check this?

are there pipewire setting independent of system settings?

I do not understand what that means.

Thank you for helping!
