Please disregard this patch.
I could get my hand on a MS Golf 3 demo, and sound is horrible.
It gets better when in case ACM_STREAMSIZEF_DESTINATION the block size is 
rounded down instead of up, but that doesn't solve the stuttering entirely 
(listening to WELCOME.WAV makes that obvious: game music loops after ~10 
seconds). Probably some rounding issue.
