#include <nnsys/snd.h>BOOL NNS_SndUpdateDriverInfo(void );
Updates the sound driver's information.
The updated sound driver information can be obtained with NNS_SndReadDriverChannelInfo, NNS_SndPlayerReadDriverPlayerInfo, or NNS_SndPlayerReadDriverTrackInfo.
Even if the update fails, information at the time the sound driver information was last updated successfully can be obtained if update has succeeded at least once.
Updating the sound driver's information involves communicating with ARM7. Accordingly, if this function is called repeatedly while processing cannot be performed with ARM7, this function will simply fail repeatedly. Therefore, call this function about once per frame.
The update will always fail the first time this function is called.
