+ Specifies which sound subsystem to use. Selecting *none* disables sound output altogether (sound hardware is still emulated). On Windows, *dsound*, *xaudio2*, *portaudio* and *none* are available.

The default is *dsound* on Windows. On Mac, *coreaudio* is the default. On all other platforms, *sdl* is the default.
On Windows and Linux, *portaudio* is likely to give the lowest possible latency, where on Mac *coreaudio* provides the best results.
+ When using the *sdl* sound subsystem, the audio API to use may be selected by setting the *SDL_AUDIODRIVER* environment variable. Available audio APIs depend on the operating system. On Windows, it may be necessary to set *SDL_AUDIODRIVER=directsound* if no sound output is produced by default.

- This controls the amount of latency built into the audio streaming. By default MAME tries to keep the DirectSound audio buffer between 1/5 and 2/5 full. On some systems, this is pushing it too close to the edge, and you get poor sound sometimes. The latency parameter controls the lower threshold. The default is *1* (meaning lower=1/5 and upper=2/5). Set it to 2 (**-audio_latency 2**) to keep the sound buffer between 2/5 and 3/5 full. If you crank it up to 4, you can *definitely* notice audio lag.
