I tried both google and brave search and have yet to come across an answer that works on my machine, a newly installed 15.6 leap instance.
Here is the output from inxi -Aa
Audio:
Device-1: Intel Tiger Lake-LP Smart Sound Audio
driver: sof-audio-pci-intel-tgl

I have sof-firmware installed, as well as the above drivers. I disabled pipewire, as I’ve had problems on Ubuntu/Mint with Pipewire. I have also tried this with Pipewire enabled and have had the same issue.
The device shows up in YaST Sound as “Tiger Lake-LP Smart Sound Technology Audio Controller.” When I select edit and try Quick Automatic Setup or Normal Setup, or Advanced, I get the following error:
The kernel module snd-sof-pci-intel-tgl for sound support
could not be loaded. This can be caused by incorrect
module parameters, including invalid IO or IRQ parameters.
As I said above, I have this working on Linux Mint 21.3 Virginia, so long as I have Pipewire disabled with the sof-firmware drivers. Does anyone have any clue what I need to do to get the sound working? It’s really the only thing stopping me from switching.
FWIW, there is what, at least to me, appears to be a similar issue here: No sound | no output or input devices found for Dell S2721DS | Tiger Lake-H HD Audio Controller - #10 however, one of the reddit links has died, and this ended up with a bug report two+ years ago; I would assume by now it would have been fixed.
Thanks
