Could you try the Leap 15.6 kernel? It can be installed on the Leap 15.5 system without problems. The very latest kernel is found in OBS Kernel:SLE15-SP5 repo, http://download.opensuse.org/repositories/Kernel:/SLE15-SP6/pool/

I tested this on a separate installation of 15.6. The problem persists. The output of aplay -l, inxi -Axx and dmesg | grep snd_hda was the same. The kernel version in the 15.6 installation was 6.4.0. As mentioned in the bug report, this has also been tested on Tumbleweed, kernel version 6.8.x. Again, the same problem and aforementioned output is identical. -- You are receiving this mail because: You are on the CC list for the bug.

Thanks. It shows the error [ 6.448531] snd_hda_intel 0000:07:00.6: no codecs found! and that's the crucial error.

Yes. The same conclusion was reached in the openSUSE hardware forum.

Did the sound work on Leap 15.4 in the past? If it's a regression, it'd be helpful to narrow down the regression range.

This is a new machine. I've never faced the situation where the CPU and the motherboard both have sound hardware. -- You are receiving this mail because: You are on the CC list for the bug.

The only detected card is card#0 and it's for HDMI/DP audio. It can't output to the analog onboard. So the situation is very same as Leap 15.6.

I have since upgraded the machine in question to Leap 15.6 with no change as expected.

...

As I mentioned there is no audio from a HDMI audio/video splitter in the path to the monitors.

It's likely a different problem. For the HDMI output, it often requires to set up the proper IEC958 bits beforehand, in addition to the choice of the right device, and it might be missing in your case.

I will investigate. Any suggestions? Getting *any* sound would be a big improvement! -- You are receiving this mail because: You are on the CC list for the bug.
