Why is the sound on Horizon/Rainbow on Windows platforms garbled/unrecogniseable?
If the sound is garbled for all the games you’ve tried then check the hardware acceleration levels for your soundcard (look in Sound/Multimedia Control Panel). Reduce the level to see if the sound improves. If the sound is garbled only for some games then it’s probably due to the limitations of the emulator. Also note that none of these emulators mimic complex sound output such as speech.
