You have to turn on your sound in the setting option in crossfire or it's a SndDrv problem. If it is you have to replace your old SndDrv.dll with a clean SndDrv.dll file in your crossfire folder
Find the SndDrv backup in this thread here (look in the attachments): http://www.mpgh.net/forum/243-crossf...-6-2012-a.html Replace it with the one in your crossfire folder. Answered and closed.
