Sound Emulation

• Disabled, but emulated tries to emulate most of the sound hardware, but doesn't actually output sound.
• Enabled will emulate all of the sound hardware, and some programs won't work with other settings.

Automatic switching allows switching between sound modes automatically.

Volume

Master volume. Set overall volume between 0% (silent) to 100% (loud).
Paula,CD,AHI Audio. Set audio from either Paula, direct CD or AHI sound between 0% (silent) to 100% (loud).
