Try with the previous post. Though the question is different but you can use following code out of that ticked answer. Refer this below code in previous post.

OSStatus errorMsg = AudioQueueSetParameter(audioQueue, kAudioQueueParam_Volume, Level);

    if (errorMsg) {
        NSLog(@"AudioQueueSetParameter returned %d when setting the volume.", errorMsg);
    }

for above code refer to documentation Controlling the Playback Level

Also refer other answers too. Also I think MPVolumeView is working with AudioQueue so you can use that also.
