Please see following results from modproble.conf and lsmod. I can see
that the soundcore was loaded, I guess the audio module was loaded,
right?

The 5.2 was installed from scratch, it was not updated from an old version.

I've checked dmesg and messages, but could not find any word to Audio,
or audio, or sound. But again, I checked dmesg and messages from my
desktop which installed FC7 and I could not find anything to audio and
sound as well.
The only suspecious I could find was following boot message, but I am
not sure it was related or not, and not sure how could fix following.

What is the name of the audio module and driver from lsmod? I can only
found soundcore as above.
Thank you so much.
