For example, choosing LPCM output from PS5, passthrough option gets greyed out in TV. Changing back to Dolby in PS5 we get Passthrough again.
But then to next problem, then we are not getting good passthrough, we often get delayed audio, depending on what Dolby encode format we passthrough. It's like the tv still does something with the audio before it passthroughs.
High resolution audio works without error if I connect directly to sound system. But not if I connect to tv and try to passthrough. So it is the tv at fault, not anything else.
