No sound after installing RX 6900xt

Support Sound

Hello,

I just replaced my GPU with a 6900xt on a fresh install of Manjaro. The only audio device that shows up on pulse audio is a virtual output called “Dummy Output”. I’m not sure what to do or what information I should supply but here’s a start

Please change the kernel, kernel 5.13 is eol.

Maybe this will help you.

I found this and followed it

https://wiki.archlinux.org/title/General_troubleshooting#Session_permissions

Although its only temporary, I can see my audio devices in pulse audio now but I still can’t hear anything.

Also, audio works when I boot into a live usb, but stops working if I install the live usb.

Please post more information about the PulseAudio devices

pacmd dump

and ALSA audio settings for the onboard audio device

amixer --card=1
