Hi there.
The experience on Manjaro has been great up until about a week or two ago when I downloaded and installed the new Manjaro update. Since then, sound has been extremely crackly on my Sony WH100xm4 headphones, which sound fine on my Windows 10 machine.
While I can’t 100% confirm that the update caused this, it’s the only thing I can think of right now that could have. Is there a way to rollback my Manjaro version, or is there an easy fix to this I’m missing? Thanks.
