The system is detecting the hardware (Family HD Audio Controller) but no sound is being outputed. I can confirm that the issue is not present in kernel 6.5.6 but going to 6.6.6 forward audio stops working. Just confirmed today that 6.6.8 does not work. Using 'alsamixer' I can control volume and mute on the card but when running 'speaker-test' or any audio from the system, no errors are shown but no audio is heard. $ lspci | grep Audio 01:00.1 Audio device: NVIDIA Corporation GA106 High Definition Audio Controller (rev a1) 05:00.6 Audio device: Advanced Micro Devices, Inc.

Possibly the same issue, or at least similar. On F38, headphones output is very very quiet with kernel > 6.6.6. 6.6.6 is still fine. 63:00.1 Audio device: Advanced Micro Devices, Inc.

It might be. I ha e the issue on both Arch and F38 when the kernel version is at or higher than 6.6.6
I was browsing the diff on each of the releases and was trying to see if there was a difference between the 6.1 and 6.6. I found this change to sound wireless was made. Not very knowledgeable on how this works and even if it could be a culprit. https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/diff/drivers/soundwire/stream.c?id=v6.6.8&id2=v6.6.7 Would someone with more knowledge be able to shed some light maybe?
This issue was fixed in kernel 6.7
