Up to wine 1.1.28 the game works normally, however, testing the newer two
versions (1.1.29 and 1.1.30) produces the following:

1. Incredible game slowdown (like a slideshow). The game slows down to the
point that it takes several attempts to register a key press.

2. Loss of background music (though ambient sounds come through) using ALSA
output (same as the issue noted on the post below)

Using OSS output I get no sound, but the game is at normal speed. Using OSS and
launching the game with "padsp wine" results in ambient sounds returning, but
the slowdown is back. No setting I've tried so far has resulted in restoring
the background music.

Under wine 1.1.28 sound works (ALSA) and the game runs at full speed.

Workaround:
Take winemp3.acm.so from /usr/lib/wine on a 1.1.28 install, and put it in
/usr/lib/wine on a 1.1.29 install.
