Before Posting :
I saw in here these two:
Just an update.
I reied out the 25.10. It comes with 6.17.05 version of kernel as of now in daly build.
When it comes to my case, with 25.10 wifi couldn’t connect, though with 6.14 kernel it works (25.04).
I really hope they didn’t do a driver “update” so it won’t work anymore
Sound wasn’t working for me with 6.14 (25.04) already so I had to recompile driver, but with 25.10 it does show as if working, but sound is not there. Tried the jack “rewiring” or what was it called,…
and this:
This is extremely weird and indicates that this module was not built for the CPU architecture you are running, did you download the file separately from somewhere or anything similar?
I have already downloaded 22.04.5 jellyfish which I have in an older 5420 with no audio issues but want to see if there is a solution instead of installing an older version.
Can you share the output of journalctl -b?

Yup
Just did it and uploaded it to the paste site:

Thanks
Edit: IDK why the ubuntu paste was deleted so I added it to pastebin
You can always paste between three sets of backticks:
```
Which turns this
```
Into This
That way you can skip the pastebin. In fact, we’d prefer that.

IDK if it makes any difference but if I connect my Arctis Pro via bluetooth, I do get audio, don’t have a 3.5mm to check physically.
To be fair, I was speaking as a moderator, not that I have any insight to your problem.

It doesn’t. Different and independent “sub-systems”. The sound card/chip, the sound chip in the graphics card/chip/embedded in the CPU layer (HDMI, DP,…), USB audio device and Bluetooth audio are all different and independent. That one works is irrelevant for troubleshooting the others.

This seems similar to Bug #2131090 “Regression in 25.10: No audio devices in PipeWire/...” : Bugs : alsa-ucm-conf package : Ubuntu
Please try installing the updated UCM package from Comment #6 : Bug #2130761 : Bugs : linux package : Ubuntu
That’s currently going through an SRU process to be released to Questing, but hopefully it resolves the issue for you in the meantime.

Thanks
Unfortunately it didn’t
I downloaded it and ran sudo apt install ./(Package name) and it didn’t install, it upgraded it as seemingly it was already there
After I did that I rebooted and checked and the Dummy output is still there
