UDIO-8 with Audiolense getting started routing, speaker check connections.

I know this is niche but I am hoping a few people might have experience with the UDIO-8 with Audiolense. So far I have set the UDIO-8 in ASIO4ALL as playback device and my external sound card/microphone as recording device. And then chosen ASIO4ALL in Audiolense as both playback device and recording device. And no sound in check speaker connections. I have also enabled output channel override.

I have the PC>UDIO-8>two separate DAC's one for high frequency and the other for low> into two separate amps > woofer and compression driver

All to no avail, just can't seem to get any pink noise for the speaker check connections. Any ideas?

I can't imagine it being different from a multichannel DAC.
