Thanks for the suggestions! Selected the Analog Dual Stereo preset and veriefied analog ins 3&4 feeding DSP B in 1&@ and DSP B out 1&2 feeding analog out 3&4. Still nothing audible from analog outs 3&4 and nothing showing at analog out 3&4 on the internal meter. DSP B machine out shows signal. I have not tried to route DSP A to analog 3&4 yet to see if I can get signal to those outputs at all.
I also checked sync settings and clock source is set to internal 48kHz.
