Comment (by csnover):

 Sorry, I misspoke earlier (actually, read the disassembly wrong the first

 The 0-arg `kDoAudio(WaitForPlay)` was changed in GK2 to return the number
 of samples that have '''not''' been loaded into memory, but the background
 music is supposed to be loaded into memory by an earlier call to `kLock`.
 Most of this code is new to SSCI in GK2. (It looks like Torin may have
 introduced some non-audio-related lock serialization code; I am still
 working on figuring out precisely where it was introduced and what it is

 As a side-note, this seems to explain the “weird” audio-lock-related
 behaviour I encountered in Lighthouse from time to time.
