Hello, thanks a lot:) I wish the same 🙂
Think about dosbox like a virtual machine – and in game profile you setup which sound card will be emulated. However, old dos games were not designed for detection pc hardware. You must manually set in game which sound card is in your pc. Probably in game directory will be program SETUP.EXE or SOUND.EXE, or something like this. Here you must setup it.
