I wonder if that wx3200 does av1 decoding
It does not. It's an old Polaris 23 GPU. AMD supports AV1 since Navi 23 (RX6600).

if an AMD wx3200 card would be a good choice to use in an LE htpc?
If you can get it for free or dirt cheap I suppose it would be an ok choice. Otherwise, there are better choices (Intel Arc A310).

vaapi is not working on 4k Hdr live streams
This is a known Kodi issue. No fix as of yet.

If you have a problem relevant to this thread then post about it here. Those outdated builds would not resolve anything.

More info here about Samsung + Gemini Lake no signal issue.
-
Goto General->External Device Manager->HDMI UHD Color (or Input Signal Plus on newer models) and disable it.
Use the normal Generic image, not Legacy.

What TV? Samsung?
-
So is it some kind of miscommunication between LE and LG TV?
It's a bug/feature of your TV's firmware. Maybe some setting in the service menu would disable PC mode.
On a Samsung TV the PC mode activates only when you change the "Device icon" to "PC".

The only change in that driver since kernel 5.10 (LE10) is https://github.com/torvalds/linux…440e5c8dfd02896. So I see no reason to revert other commits. The issue must be somewhere else.

Do you think it would be useful if I open a bug in the i915 kernel repoI'd be very surprised if this would get any attention there.
-
Any reason this isn't merged in upstream?
This disables an essential HDMI 2.0 feature. Also, the issue seem to be specific to Gemini Lake. I couldn't reproduce it with Alder Lake/Tiger Lake.

HDMI 2.0 on Gemini Lake is finicky. I came up with this kernel hack to make it work without random black screens on a Samsung TV:

is it going to a night and day difference or something minor?
It should make a big difference. I never tested it on Gemini Lake though.

111032 – Need to set gt_min_freq_mhz to max value to avoid sync issues on Gemini Lake N5000/J5005
There was supposedly a fix/improvement back in 2019.

If you can compile your own LE image you can try to build it with this patch removed. This will enable async rendering and should improve GUI performance quite a bit.
-
Did you disable "Disable screensaver when playing audio" setting?
-
Is this a bug, or a limitation of driver/software support as noted in the docs?
I don't have an RPi but I think this RPI-specific patch does the bit depth detection and sets the HDMI mode accordingly. No idea why it does not work for AV1 though.
