Output from the MBP is no longer an option since it was the DAC.

Just tested output from the TV and that did end up working. So it must be something with my DAC. I really didn't want to spend more money on a new DAC, ugh...

Correct. The only thing plugged in is the E7 into the E9 dock, USB out from Macbook to USB in on E9, power adapter, and the RCA out.

There doesn't appear to be a setting for this in the e7 or e9 manual.

Yea, it makes no difference. I just went and bought another RCA cable at the store and same thing. At least that's one thing eliminated.

Sorry for the noob question, for I am sure I am doing something stupid. But here goes... I have an e7/e9 combo that I am trying to output to the valhalla 2 I got today and there is no sound coming from the valhalla 2. The layout I have is usb from laptop (macbook pro) to the e7/e9 and then RCA...
