Points

1. The audio plugin interfaces with Project64's RSP. You must have the RSP configuration correct for the type of audio plugin (HLE or 'LLE') you wish to use.

Open the configuration dialogue of the current audio plugin from the Options menu.

Choose a non-default audio plugin if:

• you have no sound card, or a non-functional sound card - select the dummy audio plugin*
• you don't want audio or want to turn it off for more speed - select the dummy audio plugin*
• you want to use HLE audio (perhaps for more speed)
• you want adjustable or more advanced sound buffering
• you want any filtering and advanced processing options
• you want any controls that are not offered e.g. balance or reverse stereo

Assuming all those capabilties are available in another plugin.

*In this case you should also disable audio emulation in the RSP to save CPU time. Note that some games will not work with a dummy sound plugin selected, for technical reasons. For compatibility it is better to simply turn the volume all the way down.
