The Audio Writer block does not work in External Mode with Desktop Real-Time.
Is there a way to drive the audio output otherwise for Desktop Real-time?

There is a small chance that the audio board will show up as a possible output if you use the Analog Output block. But I suspect it will not, so you would probably need a custom I/O block.

Good idea. I just checked it out on 2 different machines, one with internal audio out, and another with SoundBlaster. No such luck here. I don't know how to write custom IO blocks. So it looks like I'll need add hardware.

Having Mic input and Audio output for Desktop Real-time would be great, if Mathworks' development team is listening in. Saves me having to get additional IO card for simple Analog IN and OUT.
