The BTR3 and new BTR3k in USB DAC mode work with the switch, but I got rid of my PS4 / Xbox a while back as I was playing more PC games. I was actually looking for a console fix recently - but I couldn't find a console to purchase... all the sites I checked had only used/refurb units - even MS Store was out of everything, what happened?
Anyway, I've searched before for PS4/Xbox compatibility with BTR5 / BTR3k in USB DAC mode and found nothing, just like now... weird right? You'd think someone would have tried it by now...
The BTR5 in USB DAC mode is incompatible with the Nintendo switch, but the BTR3k works, so if you want play around with testing USB DAC mode I'd invest in the BTR3k first and see if that works with the PS4 / Xbox as it's less expensive than the BTR5 and cheap enough to dedicate to the task long term if the BTR3k does work.
If you just want to use the BTR5 / BTR3k as a Bluetooth receiver with the PS4 that might work too, the PS4 advertises connecting with BT headphones (receivers) so it might just be a matter of the usual connection dance. That may be why we don't hear about the BTR5 / BTR3k and PS4 / Xbox as BT connectivity - maybe it just works?
I hope that helps a bit
Did you try switching the BTR5 from USB 2.0 to USB 1.0?
