LSPCI on Fedora 24:
I’ve been looking at the lspci output, and I have a doubt. We might need to focus on this line as well:

Fedora “Vanilla” Kernel
I’ve updated to the 6.16.1-200.vanilla.fc42 kernel. I wasn’t very confident it would work, but it did!
Now I have sound. In the GNOME sound settings, I see:
Output: Speakers - ACP/ACP3X/ACP6x Audio Compressor
Input: Soundwire microphones - ACP/ACP3X/ACP6x Audio Compressor
So, it looks like that will be supported soon in the Fedora mainstream.
I’ll contact the ELRepo team to see if they can add support for this APU’s audio in the next kernel-ml release (that can be useful for Rocky 10 users).
Thanks a lot
