I bought a Topping TP 30 Mark II.  Sounds good and it;s playing well with my new computer.


That said, I also have a pair of Audyssey Lower East Side speakers that I use occasionally when not using my cans.  Unfortunately I'mm notable to use both.  Here's whats going on:


I have the Topping running through USB obviously.

I have the speakers patched to the Mobo audio jack.


The speakers work just fine as long as the Topping is not connected.  As soon as I plug in the USB going to the Topping I lose the speakers.


I'm looking pretty hard for some kind of audio driver setting on the computer but I'm not having any luck.
