Tracking a live gig or off a console (where you can give the talent a cue mix before it hits the DAW) works fine but form my data most of the people using DVS aren't doing this. I've never had the latency low enough to get it to work. Get some audio playing so your mix is outputting on those channels. In protools, set your active sound card to be Dante Virtual Soundcard, and on your output routing set your main stereo mix for example, to route to Dante Soundcard 1-2. Were the band monitoring off DVS after it hitting the DAW? This should make the Dante sound card’s outputs 1 and 2 return on Dante line 45 and 46.
I've not had any problems using actual real Dante hardware units, but DVS seems to be presenting some randoms errors with Mac OS X on too regular a basis for me to be comfortable these days. My problem lately with DVS is that there seems to be some odd and unexplainable errors where the sample rate seems to change without warning and without actually indicating a change. Now we're using our Focusrite units and an HDX system so I don't have a need for DVS in our main recording rig any more. I don't give a rat's ass if the latency is 1 nano second or 10 seconds, as long as the tracks get written every time. This system allows the computer to record from and playback to the Dante network using most common DAW packages. Doing recordings of live performances I've tracked as many as 40+ channels at a time (using something other than Protools of course). The Audinate Dante Virtual Soundcard software allows connection of a PC/Mac to a Dante audio network. I absolutely wouldn't use it for tracking- the lowest latency value achievable is:Ĥms (for DVS) + 32 samples (for audio buffer) + 150us (for Dante converters).
I work for a gear manufacturer and we use Dante Virtual Soundcard all the time for easily getting audio out of a computer for demo purposes.
