Kernel errors - i915_drm and snd_hda_codec_hdmi

Support

Hi,

I’ve encounter two errors in Kernel (5.15.19-1) via journal message:

  1. i915 0000:00:02.0: [drm] ERROR [CRTC:51:pipe A] mismatch in has_psr (expected yes, found no)
  2. snd_hda_codec_hdmi hdaudioC0D2: Monitor plugged-in, Failed to power up codec ret=[-13]

Regarding no.2 I found such solution (grub parameter)

snd_hda_codec_hdmi.enable_silent_stream=0

but I’m not sure if it solves the issue or rather covers it?

I use laptop connected to docking station with an external monitor connected via DP. Laptop is closed all the time I work mostly on the external monitor. I use sound via HDMI. Additionally I have issues when system is booting a desktop on the external monitor is empty (no icons, it’s just black). Mouse right-click doesn’t work on the desktop. When I just open laptop and its screen is on only for a second everything on the external monitor gets back to normal. I can see icons, wallpaper and so on.

The description might be a mixture of a few issues which I’d like you to help me solve.
