I think I may know what's going on with the VR2 sound thing. Thanks to
@BWX 's advice and guidance, I got my Buttkicker Gamer 2 up and running again, after 2 years of not using it, because, issues. I discovered something while getting things adjusted on my Onkyo Rx. My PC was sending stereo signal. The Rx sounded like crap unless I had the listening mode set to a PLII mode. And the BK wasn't getting any sub signal. Swapped the output on the PC to 5.1, wiggled a couple more things on the Rx and my BK went absolutely ape💩. Clip light pretty much steady on. Tuned the BK to stop that action. Now, I can't get the PC source listening mode to even touch a PLII mode.
Now I know why it sounded better in that mode than when I forced it into a non PLII mode. The Rx was translating the stereo signal to 5.1 surround and now, since its getting 5.1 signal, it doesn't have to logically force signal to the surrounds and won't let it go into that mode.
All this leads me to think, when VR2 is powered up, the PS swaps the audio to stereo output, since PLII mode is what my Rx drops into when the VR is running. How very disappointing. Really hope Sony pushes a patch to remedy that. Kinda' kills the point of having a decent sound system to rock along with VR, just to get it hamstrung.
