Sound works with the latest 6.4 kernel: 6.4.15-200.fc38.x86_64.
I am using a Dell Inc. XPS 9320.

This may be of importance. Possibly a change in the kernel relating to this device?
Thank you for replying.
Does this not indicate the sof is installed already?

Yeah, but the warning from the error stated that the firmware of the sound device may need to be updated. Perhaps fwupdmgr --help has answers for how.
Unfortunately no firmware updates are available.

Well, at least it’s eliminated. Have you tried pw-cli list-remotes should give you one, mine looks like
[jakfrost ~]$ pw-cli list-remotes
0 = @remote:0x55c0d2f40710 'pipewire-0'
then try pw-cli list-objects and you should get a long list of objects which you can review. Mine is at least 60 objects.
The remotes are different.
Kernel 6.4.15:
> pw-cli list-remotes
0 = @remote:0x5583634438f0 'pipewire-0'
Kernel 6.5.5:
> pw-cli list-remotes
0 = @remote:0x55dd35bc28f0 'pipewire-0'
Running pw-cli list-objects on the 6.4 kernel returns 615 lines.
Running pw-cli list-objects on the 6.5 kernel returns 387 lines.
Interesting, maybe the differences between results can be helpful. You could run the commands again with both kernels and have the results redirected to a text file instead of the terminal and then diff the files to look at the differences… pw-cli list-objects > sometextfile then diff filefromkernel64 filefromkernel65 maybe
I actually did that, but I have no clue as to what I am looking for. I could upload the files if they could makes sense to someone else 
Hi @rvangsgaard ,
Sorry for the delayed response, I have a customer in break down mode and am trying to get one of their machines back up. You can use the fedora community pastebin at https://pastebin.centos.org/ to upload the two files.
Hi!
I experience the exact same issue with my Dell XPS 13.
So it really seems that the 6.5 kernel lost some audio capabilities.
Uploaded the diff from 6.4 and 6.5 here: Untitled - Pastebin Service
Maybe it is of help to anybody.
No problem @jakfrost, I just hope you got the customers machine back up?
I pasted the list-objects on kernel 6.4 here Kernel-6.4-List-objects - Pastebin Service.
I pasted the list-objects on kernel 6.5 here Kernel-6.5-List-objects - Pastebin Service.
Having the same issue. Same device, remotes, differences etc. I guess all I really have to contribute is I can help with any testing or necessary info to troubleshoot. Unfortunately, I chose now to do a fresh install, so no kernel rollback. Guess I’m building 6.4.15 for now.
I had the same issue. No sound (only dummy output) with kernel >= 6.5.5. I solved it by manually installing the firmware files from the link in the logs: https://github.com/thesofproject/sof-bin/releases
Then I just ran the install.sh script in the download and rebooted. And then there is sound again.
I guess the alsa-sof-firmware package in Fedora is simply out of date and does not currently contain the needed firmware.
@danielpettersson I am not very content with downloading and running a script like that. What about maintaining and keeping up-to-date with it later on? Will newer kernel updates work with whatever the script installs?
Today the 6.4 kernel disappeared from the boot menu (of course, because of a new version coming in), so your solution might come in handy sooner than I thought
Yeah, I agree. It is really not an optimal solution. But it works around the issue for now at least

If it is a kernel regression then there will be an update to fix it likely already in the pipeline. Sorry for the delay.

I enabled the testing repo and updated to kernel 6.5.8-200.fc38.x86-64 and the issue is resolved.

Sounds good - I am looking forward to it being released.
