Function Documentation

int sceAudioChangeChannelConfig (  int  channel, int  format )

a

int sceAudioChangeChannelVolume (  int  channel, int  leftvol, int  rightvol )

a

int sceAudioChRelease (  int  channel  )

Release a hardware output channel. Parameters: channel  - The channel to release. Returns: 0 on success, an error if less than 0.

int sceAudioChReserve (  int  channel, int  samplecount, int  format )

Allocate and initialize a hardware output channel. Parameters: channel  - Use a value between 0 - 7 to reserve a specific channel. Pass PSP_AUDIO_NEXT_CHANNEL to get the first available channel. samplecount  - The number of samples that can be output on the channel per output call. It must be a value between PSP_AUDIO_SAMPLE_MIN and PSP_AUDIO_SAMPLE_MAX, and it must be aligned to 64 bytes (use the PSP_AUDIO_SAMPLE_ALIGN macro to align it). format  - The output format to use for the channel. One of PspAudioFormats. Returns: The channel number on success, an error code if less than 0.
