The sound is fine when in Apple mode, but when booted up in Windows 10, all seems to be fine except that there is no sound from the internal speakers. The i-Mac uses a cirrus sound chip, we can't find a Windows driver for it anywhere on line. Windows says that the sound is working correctly, but still no sound!
