If I use video acceleration (checked with intel_gpu_top), the screens turn off for a second, then everything is normal egain. When the video stops playing, it turns off again.
After disabling hardware acceleration in the browser, this does not happen.
The monitors are fine. One is connected via VGA (eDP in xrandr) and the other via DVI-D (HDMI2)

I now figured out that it only happens if a monitor is connected to HDMI or DVI. If only VGA is being used (detected as eDP1 in xrandr), the effect does not occur.

Hello mm2021,
Thank you for posting on the Intel️® communities. I am sorry to hear that you are experiencing issues with the display turning off.
In order to have a better understanding of your issue, please provide me with the following:
- Are you using any type of adapter?
- Have you tried using other cables or video outputs?
- I understand that you mentioned that you have experienced this issue with a similar laptop with Windows 10. However, could you try installing Windows 10 on this specific system, to confirm if the issue is still present?
- If you install Windows 10, please, create a report using the
- Intel®️ System Support Utility (Intel®️ SSU)
- Download the Intel SSU
- Open the application and click on "Scan" to see the system and device information. By default, Intel®️ SSU will take you to the "Summary View."
- Click on the menu where it says: "Summary" to change it to "Detailed View."
- To save your scan: click on "Next"; then "Save."
Best regards,
Jean O.

I don't use any adapters or converters. I have tried other calbes, but my calbes are fine. It only occurs in the situations I described.
I also tested Lubuntu 22.10 live, the same happens, so it is not a fault of my installed Debian.
I will try out windows 10 on a second hard disk.

I have now found out that it is related to audio. If I have the internal Intel audio enabled in PulseAudio, the monitors turn off. If audio is disabled, it does not occur.

I solved it, see my post in this German Usenet newsgroup:
https://groups.google.com/g/de.comp.os.unix.linux.hardware/c/ap7jWboc3_k
Short:
I set the following boot option:
snd_hda_intel.power_save_controller=0
See that documentation for details what is does:
https://docs.kernel.org/sound/designs/powersave.html
Do you think that behaviour is a hardware issue or an issue in the Linux driver?

Hello mm2021,
Thanks for the information you provided.
We understand that the issue seems related to audio; however, as we mentioned, we may need you to test if the problem persists if you install a Windows Operating System. It is ideal to mention that our drivers are developed to work in a Windows environment. Also, if the issue persists, create an SSU report; this will gather information related to your system.
Best regards,
Jean O.

Hello mm2021,
Thank you for your response.
As the issue is present in the Linux Operating System environment, we recommend contacting the Linux* Operating System Vendors for further recommendations.
