Hello,

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 alsa-info.sh output:
Kernel 5.4: 
http://alsa-project.org/db/?f=a51d43c18273c3c79d4341e251a32542e2ee3714
Kernel 5.6: 
https://alsa-project.org/db/?f=97cd639a2a416f2a5875b7534dd39ce38c36bd93
Kernel 5.7: 
https://alsa-project.org/db/?f=31d9a277aa2e0bca24e6089ba5c1e302ec2c89a1

On Kernel 5.4 everthing is fine.

Maybe it has something to do with this?

Any idea how to fix this issue?

Thanks in advance
