Noise on low volume levels when using any digidal output device

Post by vpro »

I hear noise when using any of the digital output devices when volume is lower than 50%, and lower the volume, worse it gets.
When the music is playing at higher volume it seems to disappear, but it's noticeable during quieter moments songs can have.
Also, sound of volume adjusting that cinnamon crackles even more.
Everything is perfect when using analog outputs.
Devices I tried:
- Schiit Modi DAC, both optical and USB connections
- Asus Xonar U3
- Audio output of a monitor connected via DP.

I tried my best to exclude possibility of problems not related to software.
Tested my earphones with other devices and tested Schiit Modi with a windows laptop.

Thanks in advance for any ideas!

This is not a problem of Mint. Since posting I tried on two different computers and three different distros.
Switching to pipewire fixed this problem and caused only very minor annoyances like having to restart spotify after switching to another output.
However, this is not very simple to do on Mint, so I started using another distro after living almost 10 years with ubuntu-based ones.
