I'm incredibly new to emulator software as well as these forums so I apologize in advance for my inexperience. If I did something wrong here, please let me know. Host is a MacBook Pro running Catalina 10.15.6, guest is Windows XP professional 32 bit SP3. The only sound card that gives me any kind of result is ICH AC97. When I start the VM, it does the classic jingle on the welcome screen but cuts out halfway through it. Small sound effects on the desktop are fine, but when I run any of the games I've downloaded, those just make no sound at all. The games themselves (ISOs of the early 2000s I Spy games) run pretty much fine. I guess maybe the VM could be getting overwhelmed by the larger sound files, but I have no idea how to fix that. Or I could be wrong, which is also extremely likely. I've been trying all day to find an answer here by myself, but as a person who literally just figured out how to use an emulator last night my efforts have been fruitless. If anybody here has any suggestions I would be eternally grateful.
