Maybe give us some more information first…? ?
Seriously, it’s impossible to troubleshoot without any knowledge of what’s going on. For example, what config options are you using in Magic Dosbx? Have you configured Soundblaster in Win95 and in Starcraft setup? Is it working in other games? Etc etc, things like that.
I can confirn Starcraft is working fine, so I’m confident we can find a solution for this issue.
