To get sound to work you will need to add a bunch of dll overrides to your bottle namely:
a. dband
b. dmcompos
c. dmime
d. dmloader
e. dmscript
f. dmstyle
g. dmsynth
h. dmusic
i. dmusic32
j. dswave
k. streamci
l. dsound
There's three ways to do this:
1. Using winetricks
a. Grab winetricks, either from http://www.kegel.com/wine/winetricks or from your distribution's repository.
b. Run WINEPREFIX="/full/path/to/your/bottle" winetricks directmusic. This will fetch and add overrides for all the previous archives except dsound. You need to add WINEPREFIX, otherwise winetricks will just work the changes in your default wine directory (ie, not crossover's)
c. Grab dsound.dll somewhere on the web.
d. Move dsound.dll to /pathtoyourbottle/drive_c/windows/system32/
d. Run winecfg (using cxrun), go to the Libraries tab, then add "dsound.dll", making sure it's set to "native".
2. Without using winetricks.
Do the same thing you would've done with dsound using the previous alternative, except do it with all of the libraries listed above.
3. Using a patched winetricks.
