That makes you and me both.
First, under 5.1, do an lsmod and note the driver(s) loaded for the
audio. Might want to examine the modprobe.conf file too.
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?
$ cat /etc/modprobe.conf

; }; /sbin/modprobe -r --ignore-remove snd-hda-intel

The 5.2 was installed from scratch, it was not updated from an old version.
<snipped>
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.
PCI: If a device doesn't work, try "pci=routeirq". If it helps, post a report

I can't speak to this, I'm not familiar with the above output. I'll
look into it this evening.
Under 5.2, do an lsmod and see if the drivers were loaded. Also, after
the updatedb, use locate and see if the module is found.
What is the name of the audio module and driver from lsmod? I can only
found soundcore as above.
The module's name is snd-hda-intel. It's listed in your output from
lsmod. I see it up there, I removed most of the irrelevant (to me at
least) modules that were in there so you could more easily see it.
Thank you so much.
Kind Regards,
Jim
What's interesting about your problem is that it was mentioned in
several Ubuntu forums while I was googling. The solutions I've seen
mentioned both in Suse and Ubuntu forums is to use the latest
version of Alsa. That may require some 'by hand' installation, and I
am not sure you want to do that.
Here are a couple of links that mention the card "just working" and
issues similar to yours.

Mind the wrapping, but this link shows the controller just working.
http://ubuntuforums.org/archive/index.php/t-511058.html
Someone having the no sound problem on a different laptop make and
model, but same sound controller as yours.
I looked around for some devices with that chipset, but I don't have
any, so I can't experiment. I'll keep scouring the net.
