for everyone who might be still confused about the issue and how much of a solution / workaround this is, and what other worarounds there are:
these diagrams ignore the USB connection, as well as the connection to the PSVR headset, as those don't matter here. Also, feel free to replace 'TV' with 'receiver'.
"Solution" 1 is a hassle, especially if your PSVR processing unit is in a different compartment of your TV setup than your PS4, or if you're into cleanly routing your cables.
Solution 2 - the one proposed in this thread is cheap, and as 'easy' as a manual solution can be, as you'll only have to unplug 2 cables from the back of your PSVR box and 'bridge' both ends via a splitter that you'd (as suggested) just stick onto the box itself. - it's a simple bypass
Solution 3 is possibly the most comfortable, but the most expensive, also, some switches can be iffy with HDCP, 4k, HDR and whatnot - i'd prefer to not plug in yet another device into the chain between my PS4 and my TV.
Also, if you were only using one switch then, while you'd have split your HDMI signal to go TO your PSVR box and towards your TV seperately, but where would the cable from your PSVR go? so you'd either have to use yet another switch that has 2 inputs -> 1 ouput or you'd have to use 2 HDMI ports on either your TV or your receiver.
personally, i think i'm gonna go with the coupler. since your PSVR box needs to be SOMEWHAT accessible anyways (for the sake of plugging in your PSVR headset).
And yes, a
huge blunder by Sony, but them's the breaks...
