My 2cents on this, and I apologize as I don’t think I can help in regard to what appears to me to be an alsa level issue.
What sort of interface is this “front panel audio device” using? Is it an audio jack, or are you referring to a USB port. I note that according to that diagnostic script your PC has four instances of “snd_usb_audio” running in addition to two instances of “snd_hda_intel”.
Note by default, openSUSE will send sound to sound card-0, which in your PC case is actually a USB device (a webcam, I think). I deduce that from:
!!Loaded ALSA modules
!!-------------------
snd_usb_audio (card 0)
snd_hda_intel (card 1)
snd_hda_intel (card 2)
snd_usb_audio (card 3)
snd_usb_audio (card 4)
snd_usb_audio (card 5)
and
!!Soundcards recognised by ALSA
!!-----------------------------
0 [UVC ]: USB-Audio - GENERAL - UVC
GENERAL GENERAL - UVC at usb-0000:04:00.3-1, high speed
1 [HDMI ]: HDA-Intel - HDA ATI HDMI
HDA ATI HDMI at 0x81da0000 irq 163
2 [Generic ]: HDA-Intel - HD-Audio Generic
HD-Audio Generic at 0x81c00000 irq 165
3 [FOX ]: USB-Audio - FOX
Beyerdynamic FOX at usb-0000:48:00.1-1, full speed
4 [Audio ]: USB-Audio - Aorus Master Main Audio
Gigabyte-Aorus-Master-Main-Audio
5 [Headphone ]: USB-Audio - Aorus Master Front Headphone
Gigabyte-Aorus-Master-Front-Headphone
When I look for the mixer for card-2 (ie the HDA-Intel - HD-Audio-Generic) is see:
!!-------Mixer controls for card Generic
Card sysdefault:2 'Generic'/'HD-Audio Generic at 0x81c00000 irq 165'
Mixer name : ''
Components : ''
Controls : 0
Simple ctrls : 0
that does NOT appear to be working.
When I then look at the dmesg I note:
6.090235] snd_hda_intel 0000:23:00.1: Force to non-snoop mode
6.093824] snd_hda_intel 0000:25:00.4: no codecs found!
This looks to me to be an alsa problem.
Further, I am taken back by the number of packages installed for alsa:

I can’t recall ever seeing that many before.
That puzzled me … so I surfed on the motherboard and noted this:

There are other posts as well, of GNU/Linux audio issues with this hardware.
Given the # of alsa packages installed, and given the number of additional USB devices connected, and given the new nature of this hardware, I don’t think I can help.
If someone else does not chime in on how to sort this, you could either be in bug reporting territory, or you may need to try a re-install to clean up what appers to me to be a bit of a mess.
