[RPI4] 12.0.1 fresh install on RPi4 no audio or high resolution

So I just installed LibreElec 12.0.1 image on a fresh mSD card on an RPi 4 model B. When I go to the Audio settings, there's only Bluetooth. Nothing else. Likewise the Display settings, only goes up to 1024x768. So what gives?

Probably bad HDMI connection, can't detect the display properties.

Try another cable, another port...

So not sure exactly. I had it flashed with the latest 11.x, started up fine on HDMI0, and audio/1080p/etc. Flashed with 12.x but this time used HDMI1 port, worked fine too *shrug*

Also, strangely, seems to be running 6.6 kernel. My other install I had, 11.x, upgraded to 12.0.1, it's running 6.11 I think. What gives? Shouldn't 12.0.1 install with the newer kernel?

Now time to figure out how to use pulseaudio or pipewire...I want to be able to run Snapclient & switch back and forth to the play video/etc without having to reboot after enabling/disabling Snapclient, that sort of thing. Any good guides you know off hand for that before I try and find a good one? I've done some searching, but haven't been able to find one that makes things clear.

Huh, I can't edit my post. Anyway, hopefully this will be approved before you have to respond.

Found https://zanevaniperen.com/kb/0015-force-…lec-pulseaudio/, with a link to a helpful forum post as well.

After a bit, got Kodi switched over to Pulse and working (at least, GUI sounds, not sure about pass-through). Then had to manually edit the snapclient service file to get it to start up, and apparently connected to Pulse, and connected to my snapserver. Unfortunately, no audio output

I'll have to pick back up on this later unfortunately. Anyone have any thoughts on this?
