Perhaps just make the mix buffer larger for the sim?
I have no real idea how to get around this while keeping SDL
(and hence portability).
I think you're right about this and I'm going to give that a try next.
The sim audio driver still won't "DMA" like a target but at least it
ought to fill the buffer as SDL expects. Latency will skyrocket
though. Instead of 23 ms tops it'll be more like 250 ms. I guess this
isn't a problem as long as we're just using the sim to test code, but it
might if we're going to use it as a basis for Rockbox-as-app. In that
instance, the Rockbox mixer code would have to be thrown out in favor of
SDL mixer or some other library function.
