So a bit more testing. What does the overhead of running the audio mean in terms of performance visually? Well, this is the K3 we are talking about so it's not like watching an IMAX but the performance while running the sound comes out at a perfectly acceptable:
861 frames in 149.8 secs = 5.7 FPS
Whereas without the sound it weighs in around:
969 frames in 149.8 secs = 6.5 FPS
Showing us that a few frames were dropped but meh, it was not perceivable to my eyes thanks to GM's very tidy drop frame code. This gives me enough hope to try and squash some waves through the demo. and possibly - glue - the video code into my audio loop.
