If I understand you correctly, it does indeed (DoSound versus DoAudio). We
need to be able to return accurate time measurements for audio as well -
lip synch and other game-related events are handled by fetching a resource
of type SYNC and checking time stamps in this file against the data
returned by the driver. CD audio probably supports cues as well.

Agreed - especially if we're talking CD audio. And it will be even worse
for SCI32 - I have a sound byte here which is approximately 2MB in size.
