Still no luck seems like Im getting an error message , as cannot overwrite an existing file
That tells us that it is already included though- and not a likely solution.
Sigh...
Back to the drawing board...
Time to do some experiments using alsamixer I reckon.
From terminal (Ctrl+Alt+T), type alsamixer
Hit [F5] to display all your sound channels, i.e. both capture and output.
Post a screenshot on here and we will have a look.
Hit [F6] and select the rt5645 card.
Then post screenshot of sound channels.
Good.
Every channel that you see marked MM is currently muted.
So starting from the Headphone channel on left unmute by typing "M" (without the quotes"
I suggest you unmute all channels marked MM as experiment.
You can save your alsamixer settings using the terminal command:
sudo alsactl store
PS: I hope your problem with sof-bytcht is easier to fix than this one:
EDIT: I have also done a websearch using "sof-bytcht rt5645 Ubuntu 20.04"
Results include ref to alsa changes v1.2.2. v1.2.3. @Aravisian may be able to understand it better than me.

Can you [F5] for all sound channels and do screenshot again.
OK. I was looking to see if you had a 'Loopback' setting or a 'Auto-Mut(e)' setting you could have a play with. But seems not.
I am out of ideas now myself, but others may be able to help.
My main concern is that you may have to use a different kernel or Linux distro as the other user with sof-bytcht sound @heerenleed did.
Tried this?:
Installer:

Tried this still no luck

What about:
sudo lshw -c multimedia
Here's the output it shows as unlcaimed
sudo lshw -c multimedia

Ok, this is a clue that may help get us somewhere...
https://bugzilla.kernel.org/show_bug.cgi?id=109051
This is built specifically for Microsoft with a lot of the Driver Information locked in Proprietary.
As such... Getting Linux support is less easy.
I was able to find a beam of hope:
The mentioned script is here:
https://drive.google.com/file/d/1bIJTzBdMDejj8-6Er8EecjYSDcvULbPx/view
Ran the script , doesn't seem to work yet.
Just an observation , When i Turn on SPOR SPK Volume R or L, there seem to be a crackling sound .
Rephrase - a beam of hope was maybe just a spark of hope...
Seems like it was something to do with alsamixer, tweaking a few things got the sound back . But i did a fresh Zorin 16 Pro install again and seems like Sound is working now.
Thanks to everyone for all the help
