No HDMI audio with newest kernel update

I had HDMI audio working perfectly, but the newest kernel update came out, and it appears to no longer be working.  The issue is on both the newest linux and linux-lts.

Here is some relevant info:

Laptop: Dell Precision 5680

[   20.239123] usbcore: registered new interface driver snd-usb-audio

I am assuming the line about no PCM in topology is relevant.

I tried creating /etc/modprobe.d/sound.conf with the following contents:

options snd_intel_dspcfg dsp_driver=1

Which makes it fall back to HDA audio.  The hdmi audio does work this way, but then I have no microphone

I tried deleteing .local/state/wireplumber, and then rebooting, just in case that was causing issues.

Any suggestions or advice?

Re: No HDMI audio with newest kernel update

What does "latest kernel update" mean? From which kernel version to which kernel version? Generally this is a kernel bug and trying to workaround with userspace fixes/kernel parameters not previously necessary should be the last resort, and you should identify the faulty commit and report a bug upstream

Re: No HDMI audio with newest kernel update

Ahh, that makes sense.  I will see what I can track down.  Thanks for the help!  For reference, that would be 6.7.4.arch1-1 and 6.6.16-1

Re: No HDMI audio with newest kernel update

That's a major kernel version worth of differences and likely not exactly trivial. There have been some issues here when people blacklisted i915 which doesn't appear to be the case here though
