void voice_set_playmode(int voice, int playmode);
Adjusts the loop status of the specified voice. This can be done while the voice
is playing, so you can start a sample in looped mode (having set the loop
start and end positions to the appropriate values), and then clear the loop
flag when you want to end the sound, which will cause it to continue past the
loop end, play the subsequent part of the sample, and finish in the normal
way. The mode parameter is a bitfield containing the following values:
Plays the sample a single time. This is the default if you don't set the loop
Loops repeatedly through the sample, jumping back to the loop start position
upon reaching the loop end.
Plays the sample from beginning to end. This is the default if you don't set the
Reverses the direction of the sample. If you combine this with the loop flag,
the sample jumps to the loop end position upon reaching the loop start (ie.
you do not need to reverse the loop start and end values when you play the
sample in reverse).
When used in combination with the loop flag, causes the sample to change
direction each time it reaches one of the loop points, so it alternates
between playing forwards and in reverse.
