New N2+ with latest Coreelec, HDMI sound issues, buffering all the time

My N2+ is connected directly to my TV with a HDMI cable.
Running CoreELEC 19.2-Matrix_rc3

Every time I start a video, the buffering circle appears for 3-5 seconds and this happens around every 30 seconds to every minute all the way through the video.
On the same TV (A Philips with Android TV) I also have Kodi installed and here there are no issues.

For some it writes this in the log:

For others it’s:

I have tried pretty much all settings under AUDIO for Audio Output devices and passthrough, but none of them works properly.

What to do? Is it an audio/HDMI issues or some buffering values that should be changed?
Would have uploaded Kodi.log but apparently new users can’t.

If you selected HDMI as your audio device, make sure that number of channels is set to 2.0.
You can select HDMI MultiChannel PCM audio device, and then you can select 2.0 or 7.1 channels.

I tried both, but the buffering circle still shows up. I have a soundbar attached to the TV via HDMI ARC. Would the right selection be the PCM one and 5.1 so I get a more proper surround sound from the soundbar, which is supposed to play surround sound?

No, only 7.1 or 2.0 modes are properly supported.
This should not present an issue, though.
