Is it possible to play multiple sound files simultaneously (like a mix) on Apple Watch?

Question

This is the code I am using to play a sound with AVAudioPlayerNode . It is just playing the last sound of the beats array. On iPhone, all sounds from the beats array are playing simultaneously with the same function.

-(void)playMix{
for (int i = 0; i< mix.beatsArray.count;i++) {
    beat = [[WatchBeatObject alloc] initWithFileName:mix.beatsArray[i].fileName];
    [beat.audioPlayerNode play];
    [beat.audioPlayerNode scheduleBuffer:beat.buffer atTime:nil options:AVAudioPlayerNodeBufferLoops completionHandler:^{
    }];
}

}

NB: Method initWithFileName: handles initializing and creating AVAudioPlayerNode and everything needed.

Thank you in advance.

Answer 1

Does that WatchBeatObject has any category option in AVAudioSession to set AVAudioSessionCategoryAmbient? If yes, set it, they would mix different sound.
