当我们使用AVPlayer播放时，我们如何静音音频

Question

我正在使用下面的代码播放音频文件。

    -(IBAction)hearAudioMessage:(id)sender
{
ChatObject * obj = [chatArray objectAtIndex:rowIndexInt];
 NSString *str=[NSString stringWithFormat:@"http://www.myserver.com/files/%@",obj.voiceFileString];
    self.palyer=[[AVPlayer alloc] initWithURL:[NSURL URLWithString:str]];
    [self.palyer play];
}

现在，我想在播放时将音频静音。

我使用了下面的代码，但是它不起作用

NSArray *audioTracks = [asset tracksWithMediaType:AVMediaTypeAudio];
NSMutableArray *allAudioParams = [NSMutableArray array];
for (AVAssetTrack *track in audioTracks) {
    AVMutableAudioMixInputParameters *audioInputParams =
    [AVMutableAudioMixInputParameters audioMixInputParameters];
    [audioInputParams setVolume:0.0 atTime:kCMTimeZero];
    [audioInputParams setTrackID:[track trackID]];
    [allAudioParams addObject:audioInputParams];
}
AVMutableAudioMix *audioMix = [AVMutableAudioMix audioMix];
[audioMix setInputParameters:allAudioParams];
AVPlayerItem *playerItem = [AVPlayerItem playerItemWithAsset:asset];
[playerItem setAudioMix:audioMix];

请建议其他替代方案?或者当我们使用AVPlayer播放

时如何静音音频

Thanks in advance
