59<p>
60Sends audio data of 1 to 20 bytes in length to the Wii Remote on the specified channel. Because the Wii Remote can play 4-bit, 6-kHz audio data, be sure to send 20 bytes of data every time interval given by <code>WPAD_STRM_INTERVAL</code>.
61</p>
62<p>
63This function registers the command used to send audio data to the library. The WPAD library processes registered commands when other commands are not running. The processing result of the command for sending audio data registered using this function cannot be obtained.
