Arguments

Return Values

If the audio data is sent successfully to the Wii Remote using the WPADSendStreamData function, TRUE is returned. Otherwise, FALSE is returned.

Description

Checks whether audio data can be sent to the Wii Remote on the specified channel. Currently, audio data is known to break up under the conditions listed below during playback through the Wii Remote speaker. Once the audio breaks up, the speaker needs to be stopped and restarted.

• A long period where the signal state is bad
• Connection/disconnection of External Extension Controllers
• An attempt to connect another Wii Remote

To avoid audio break-up, use this function to check whether the audio can be sent before calling the WPADSendStreamData function. Also, because the internal command queue is referenced during the check, please disable interrupts between the calling of this function and the WPADSendStreamData function.
