So I know this has probably been asked a million times but I downloaded the Dosbox free Arena game and I love it but one issue: There is no sound. I am playing on windows 7 and runs the game perfectly fine but has now sound (and yes, my speakers were on and volume maxed lol). Can anyone give me a tutorial on how to fix this??

Configure the sound with install.exe in dosbox. Try different sound cards to see if they work. You can test each one while configuring.
