Dolby Pro Logic II decoder
Some titles support 5.1 surround sound via Dolby Pro Logic II sound encoding. Dolby PLII uses matrix encoding to embed a 5.1 surround mix inside a standard 2.0 stereo signal; enabling 5.1 sound from standard RCA stereo jacks, without the need for additional audio hardware, jacks and wires (e.g. optical toslink).
Dolphindecodes Dolby Pro Logic II natively, without needing an external decoder (like an A/V receiver). 5.1 speakers are needed, please test to ensure speakers are properly setup, configured and working in your computer's audio settings before attempting.
In order to activate DPLII decoding:
- Close any running games (you can save your progress by setting a save state)
- Go to Options -> Audio Settings ensure the option for "Dolby Pro Logic II Decoder" is checked.
- In order to work, you may have to turn on DPLII inside the game's settings. Check the in-game menu to see if you can change from stereo output (2.0) to Dolby Pro Logic II output.
