Which thread(s) are you locking? FYI, SDL has its own thread for audio, and SB sound generation might be using DMA, but you can probably use SDL_mutex locks to avoid collisions there.

I have a separate thread to handle Rendition DMA transfer within dosbox. SDL_mutex? I'll check it out thanks.

Have you looked at the DMA callback in sblaster.cpp as an example for handling the transfer data?

I'll check it out. Had a few other things to sort out. It never went even occurred to me check out the sound blaster code.

That worked fabulously well. Thanks!!! I get a bit of audio stutter now every once in a while.
