Description of problem:
HDMI/DisplayPort audio output does not work out-of-the-box in a default install of Fedora 35 Silverblue. I had to edit /etc/modprobe.d/snd-intel.conf to get it operational.

Version-Release number of selected component (if applicable):
Fedora 35 Silverblue 35.20220112.0 (BaseCommit 488b*10fd)

How reproducible:
Install f35 sb on a Besstar Tech Ltd. GK41, or other PC with similiar HW.

Steps to Reproduce:
1. fresh install of Fedora 35 Silverblue on a Besstar Tech Ltd. GK41 
   and "rpm-ostree update" to latest version
2. attach a monitor with speakers via HDMP or DP cable
3. => HDMI/DP is _not_ selectable as audio output device in Gnome settings
4. create /etc/modprobe.d/snd-intel.conf with this contents:
   "options snd-intel-dspcfg dsp_driver=1"
5. Reboot
6. => HDMP/DP is now selectable as audio output and works fine

Actual results:
Need to tweak modprobe configuration to make HDMI/DP audio output operational.

Expected results:
Should work out-of-the-box.

Additional info:
See attached hwinfo.

HDMI/DP - sorry for the typo

I am also having this issue. I am running i5-8250U on Acer Swift SF514-52T with Fedora 36.

By enabling the "options snd-intel-dspcfg dsp_driver=1" (HDaudio legacy driver), my speakers and HDMI audio will work. But my laptop mic (DMIC) will not work, which is the expected behavior, see https://thesofproject.github.io/latest/getting_started/intel_debug/introduction.html.

My alsa-info with driver=1: http://alsa-project.org/db/?f=726b7d21836ff2fd8115b96bc2b29f509c1855b3

"options snd-intel-dspcfg dsp_driver=2" (SST driver - default setting on Fedora 36), everything works except for HDMI audio doesn't work.

My alsa-info with driver=2: http://alsa-project.org/db/?f=41d2be23c793ab9b65412e40b2870bd8b1ab3ec4

"options snd-intel-dspcfg dsp_driver=3" (SOF driver), everything is not working, no sound card detected.

My alsa-info with driver=3: http://alsa-project.org/db/?f=8542e92049210a9185600e2d049aee38beb09add
