I am running Mac OS 9 through SheepShaver on Windows 10, and I can't get sound to work. I am using an Old World ROM because the New World ROM doesn't work, it causes SheepShaver to crash.

I tried to select the Built-in option in the sound control panel in SheepShaver, but there are no output options.

I have a bunch of ROMs from archive.org, and I'm not sure which one to use IF the ROM is the problem

  • not only Windows 10. I believe all Windows versions are affected

You need to delete the Apple Audio Extension.

  1. Open your Mac OS 9 HD.
  2. Go to System Folder
  3. Go to Extensions
  4. Move Apple Audio Extension into Trash and empty your trash.
  5. Restart SheepShaver
  6. Open Sound Panel.
  7. Select Built-In.
  • Are you sure that deleting the Apple Audio Extension won't remove features?

    It shouldn't. It worked for me. Jul 31, 2016 at 10:14
  • There's no Apple Audio Extension in there for me...
