Sorry to bother you again, I'm also thinking my pc surround issues may be solved by getting a gen 2 beam.
So the LGCX passes through LPCM no problem?
It's hard to get a definitive answer on Google as I see a lot of threads about people saying it shows up as 7.1 instead of 5.1 and causes all manner of issues but then these are threads from a while back and may have since been sorted via updates etc
Not really an issue with the PC as you can just use Dolby Atmos over eARC.
