To answer this question, essentially yes. winemp3 (now l3codeca.acm) implements
the decoder for the old ACM API (which in fact only deals with WAVE files).
Most games don't try to load l3codecx.ax explicitly, so they go through
winegstreamer instead. If this one does, I guess the best way forward is
probably to make use of libmpg123.
