Fedora 42 Audio extremely loud / Buzzed / distortion.

[Maiq_The_Liar]

I installed Fedora 42 on my ThinkPad P1 Gen 7 laptop.


Everything works fine except the audio. There are two main issues:

1. Initial loud burst / buzzing:
   Whenever I start a YouTube video (or other audio source) on a higher volume setting, the sound is suddely extremely loud for about two seconds. It’s so loud that it actually buzzes/distorts. After that, the system automatically reduces the volume to a normal level.
2. Automatic volume scaling (volume limiter):
   If I set the audio to a comfortable level and then try to increase the volume, the system immediately scales it back down, almost as if there’s a built-in threshold or limiter that can’t be exceeded. This makes the maximum usable volume too quiet for my taste.
   Even when watching a video on normal volume, the audio quality often changes suddelny from a crisp/ clear sound to a dampened/ muffled sound that is not as loud as I would wish. This usually happenes 10 seconds into the video

I already tried tweaking settings in pavucontrol (Volume Control), but nothing changed.


Has anyone experienced something similar on the P1 Gen 7 (or other ThinkPads) with Fedora? Any suggestions on how to disable this automatic scaling/limiter or get rid of the initial “buzzing burst”?
Audio stack: PulseAudio (on PipeWire 1.4.8)
