Dear Karl,

I'm on Fedora 32 with a Navi14 GPU (PULSE RX 5500 XT 8GB) connected via HDMI. Since Kernel 5.6 I have a crackling sound with some echos. It seems the crackling are getting worse when music and voice are come together.

Here are the output:
Kernel 5.4: Kernel 5.6: Kernel 5.7:

On Kernel 5.4 everything is fine.

Maybe it has something to do with this?

No idea.

Any idea how to fix this issue?

The fastest way to get this fixed is to bisect the issue, as you can do that yourself. If that is not possible, maybe at least pinpoint the (release candidate) version the regression started happening. (It’s not clear if 5.5-rcX is affected, right?) Maybe Fedora already offers such packages.

Either way, please create an issue in the kernel Bugzilla [1], and reply to this message with the bug report URL.

Kind regards,
