<H3>Return Value</H3>
On success, the number of subchannels is returned<BR>
On failure, 0 is returned.<BR>
<H3>Remarks</H3>
A multichannel sound, only possible with the .FSB format, can contain multiple subchannels. When a multichannel sound is played, multiple channels are allocated at the same time.<BR>
For example, a 8 sounds/streams can be interleaved into a multichannel FSB. This function would return 8, as 8 real hardware/software voices are used during playback.<BR>
FSOUND_GetSubChannel can be used to get access to the secondary channels.<BR>
