There  is an article about this at the sons of thunder website:

Which describes almost exactly the sort of problems you are having 
and a potential solution.

Seems to work fine here now in 2.4.3. It's a major hack internally, 
though, because of bugs in QT recording (we have to always record CD 
quality to a QT movie and then use a conversion function to output 
the type of file requested).

Be sure you're recording to a format that "play audioClip" 
understands, which mostly rules out all of the compressed formats QT 
can produce. If you must play those, use "play videoClip <file>" 
instead. That uses QT, which although much slower and more memory 
intensive can play many more formats than the default play command 
which uses low-level sound routines in Win32 and MacOS which don't 
support compression.
