Hi Robin,
Gigabyte Z490 VISION G mainboard (Intel Z490 Chipset)
From in-depth review (2019) https://latestintech.com/gigabyte-z490-vision-g-review/
"... five 3.5 mm audio jacks and S/PDIF optical output which are controlled by a Realtek ALC1220-VB HD audio codec."
From https://www.gigabyte.com/Motherboard/Z490-VISION-G-rev-1x#kf
Unfortunately in neither of those articles do the words match the included pictures of the back panel connectors of the Z490. The pictures show only the 3.5mm TRS jacks - no S/PDIF at all - which is what I have.
"ALC1220-VB Enhance 114dB(Rear)/110dB(Front) SNR in Microphone with High-End Audio Capacitors"
There is very good kernel driver support for Realtek devices.
Have you inspected the settings in PulseAudio Volume Control under the "Configuration" and "Output Devices" tabs?
Yes. Same as with the System Settings Audio module, there are a number of offerings, mostly analogue but including Digital Stereo (IE958) output. But if I select that, there's no sound. So I'm limited at the moment to the Analog Surround 5.1 output that plays through the Line Out jack and the two RCA connectors. A further oddity is that under the "Audio" settings module and the "Test" button, all five of the speakers show up but only the Front Left responds. Yet they all work when playing a track or other sound. Weird. The only thing I can add is that I also have an nVidia GeForce GPU aboard, which has its own HDMI sound chip. In previous (some time ago) editions of openSUSE I recall it was necessary to blacklist its driver ("snd_intel_hda"?), but that hasn't been the case in the last few Leaps. Anyway I can't find an OK way to do it in 15.4. To go back to the beginning - given that the system seems largely happy with the Line Out analogue connection, what I'm really hoping for is some means of getting Logitech's three-wire "six-channel direct" connection to work as it's supposed to do. In my experience, PAVC is essential for taming audio issues like these
on Linux.
