Sound distortation after 143.0.3 update

I am facing YouTube/Spotify sound being distorted in sometime for about 1-5 seconds, then it comes to normal, and then being distorted again so on. I am not sure whether the root cause came from my laptop, Windows 11 (23H2), or Firefox browser (143.0.3). I never faced such occurrence before updating Firefox version.

Update: I think the root cause is coming from 143.0.3v Firefox since I tried playing an mp3 file on Windows 11 but there is no distorted sound at all.

Hi. I've just had a similar problem. I use an older Creative soundcard with Win 10 drivers under Win 11 and right after the 25H2 update I experienced audio distortions in YouTube and only when using that soundcard. With my bluetooth headphones no problems at all. My first guess was that the drivers finally reached their EOL but as it only affected YouTube I didn't gave up. So I checked all the settings of the Creative SoundMixier and changed the output from 5.1 to 2.1 and that fixed it for me. Maybe you are faceing a similar problem as 143.0.3 and Win11 25H2 pretty much came out around the same time.
