I recently (~2 weeks) switched to Ubuntu and the sound is crazy distorted at volumes higher than 50%. At 50%, the speaker volume is not high enough for regular usage. I've so far tried tweaking around with AlsaMixer and replacing PulseAudio with Pipewire and neither solved my problem.
How do i fix this?
To see a sample of the distortion, here's a 45 second video. You can skip ahead to 35 (-10) seconds / 15 (-30) seconds to hear the distortion.
Note - this isn't an issue with the speakers/hardware as they worked perfectly fine when I used Windows.
I own an Acer Swift 3 (2018 version) - SF314-52. Terminal Output of sudo lspci -v:
