[alsa-devel] HDA HDMI audio doesn't work on Intel Geminilake machines
We have several Geminilake laptop and desktop machines, on these machines, the HW configs are same and are as shown below:
the HDA controller: 00:0e.0 Audio device [0403]: Intel Corporation Device [8086:3198] (rev 01) the HDMI codec: Vendor Id: 0x8086280d VGA controller: 00:02.0 VGA compatible controller [0300]: Intel Corporation Device [8086:3184] (rev 01) (prog-if 00 [VGA controller])
The problem is if we boot the system without plugging the HDMI monitor, the Linux kernel can't find HDMI codec at all. If we plug the HDMI monitor before booting up, the kernel can find the HDMI codec, but there are many errors (as shown below) and the HDMI audio can't play any sound.

We have tested the latest mainline kernel, but the testing result is the same.
So does the existing kernel driver support the HDMI audio well for Geminilake? If it does, what is wrong with those machines, HW issue or BIOS issue?
Thanks in advance.

Please create a bugzilla. Share the logs after applying the attached test patch. Note to enable the debug logs.

Hi,
Yes HDMI audio is tested on Geminilake. Can you please share information on model you are testing? Also what is the BIOS version you are using?
BIOS issue?
Yes this may be a BIOS issue as well.

Thanks in advance.

Hi,

They are all Dell laptop or desktop machines which are not released to market yet. The BIOS version of one of the laptops is 0.3.4.
And I will try to upload logs to the bugzilla.
Thank you.

Yes this may be a BIOS issue as well.

The bug was created, https://bugzilla.kernel.org/show_bug.cgi?id=197785
If need me to do more tests, just let me know.
Thanks in advance.
