SUMMARY

I've set the "Volume change step" setting to 2% for more precise volume control. I have also disabled "Play audio feedback for changes to audio volume" setting.

With those two options combined, the step is still 5%, although I have 2% configured. When I turn audio feedback on again, volume change step is respected

STEPS TO REPRODUCE
1. Set volume change step a value different than 5%, let it be N%
2. Disable "Play audio feedback for changes to volume"
3. Change volume with Fn keys

OBSERVED RESULT
Volume changes in 5% increments

EXPECTED RESULT
Volume should change in N% increments

Comment 1 Zakhar 2025-10-23 14:48:32 UTC 
I think I've found the reason - KMix settings still show 5% as volume step, and this setting doesn't seem to be synced with system settings.
When I change volume step in KMix and restart it, I get the desired behavior.
Comment 2 Nate Graham 2025-10-23 15:49:52 UTC 
Yeah, please use the System Settings GUI for this. KMix is all but abandoned.

I think we misunderstood each other. I *am* trying to use the system settings, but, in practice, this setting is taken from KMix, not from system settings.
That is where the bug lies.
Comment 4 Nate Graham 2025-10-23 16:15:17 UTC 
Right, because KMix overrides it. If you don't have KMix installed, you won't see the issue.
Comment 5 Zakhar 2025-10-24 10:02:04 UTC 
Oh, thanks.
It turns out kmix is a dependency of kde-multimedia-meta package on my arch system. Removing it fixed my problem.
Should I leave the bug open?
Comment 6 Nate Graham 2025-10-24 14:09:17 UTC 
Yeah, technically it's a KMix issue.

Also, I would in general not rely on metapackages in distros. They're not very flexible, and you can't remove individual contents without removing the metapackage.
