internal and external speaker in webrtc ios

[Yura Lapytko]

Hi.

This question is when i run webrtc ios application on iphone only internal speker works. 

I should put iphone to my ear if i want to hear. 

How to switch on load speaker?

Thanks.

you need to change the audio path:

AVAudioSession* session = [AVAudioSession sharedInstance];

BOOL success;

NSError* error;

success = [session setCategory:AVAudioSessionCategoryPlayAndRecord error:&error];    

if (error)

    NSLog(@"AVAudioSession error setting category:%@",error);

success = [session overrideOutputAudioPort:AVAudioSessionPortOverrideSpeaker error:&error];

if(error)

    NSLog(@" AVAudioSession error changing route:%@",error);

Thanks.

It worked in previous version but now it doesn't work. I try to use AVAudioSession in the last AppRTCDemo for ios and nothing.

Please help.

webrtc::VoEHardware->SetLoudspeakerStatus(true)

can you call it?

[Yura Lapytko]

No, how to call it and where do you call it?

[chinahu]

oh. i had buit webrtc native code . so i can call it from UI.

you can search 'SetLoudspeakerStatus' from source code.

Just use :

    AVAudioSession *audioSession = [AVAudioSession sharedInstance];

    [audioSession setCategory:AVAudioSessionCategoryPlayAndRecord withOptions:AVAudioSessionCategoryOptionDefaultToSpeaker error:nil];

    [audioSession setActive:YES error:nil];

This will also let you use headphones when plugged in.

This doesn't work any more. Is there some other solution for this problem?

I manually export the AudioDeviceModule interface and its SetLoudSpeakerStatus function from VoEBaseImpl， but it doen's work also.

I'm having the same issue. Is there no way to to route audio to the iPhone loud speaker?

I tried to use AVAudioSession sharedInstance to re-route to speaker. But it doesn't work. Anyone has a solution for this?

- (void) toggleAudioOutput:(NSString *)message {
if ([message isEqualToString:@"speaker"]) {
NSError* __autoreleasing err = nil;

AVAudioSession* audioSession = [AVAudioSession sharedInstance];
[audioSession

overrideOutputAudioPort:AVAudioSessionPortOverrideSpeaker error:&err];
} else if ([message isEqualToString:@"handset"]) {
NSError* __autoreleasing err = nil;

AVAudioSession* audioSession = [AVAudioSession sharedInstance];
[audioSession

overrideOutputAudioPort:AVAudioSessionPortOverrideNone error:&err];
}
}

Still not working when mute switch is ON. Testing on iPhone 5C.

Finally I've found a solution for this problem.

You need to set AVAudioSession category to AVAudioSessionCategoryPlayback but for some reason it gets back to AVAudioSessionCategoryPlayAndRecord.

So I added listener to AVAudioSessionRouteChangeNotification notification and set AVAudioSessionCategoryPlayback if it was changed. A bit of hack but worked in the end.

You can check it at github: https://github.com/josipbernat/JBSoundRouter

I tried your solution, but it still didn't work. I doubt that the code where I call "self.onRouteToSpeaker(self)" isn't proper, could you please show me where you call with detail. Thank you a lot.

 AVAudioSession* session = [AVAudioSession sharedInstance];        

 [session setCategory:AVAudioSessionCategoryPlayAndRecord error: &error];

 // [session setCategory:AVAudioSessionCategoryPlayback error: &error];

 [session setActive:TRUE error:&error];

it works for me. i have test on iphone5 and iphone5s

but there are errors in console. details as follow:

2015-01-31 10:36:09.613 rtc.iPhone[4583:b917] 10:36:09.613 ERROR:     [0x994d000] AVAudioSessionUtilities.h:88: GetProperty_DefaultToZero: AudioSessionGetProperty ('tlic') failed with error: 'tac!'

[Josip Bernat]

I've updated source code on github. Be sure to call JBSoundRouter.routeSound(JBSoundRoute.Speaker) after you receive RTCMediaStream from other peer.

[Antonis Tsakiridis]

Isn't the webrtc implementation supposed to honour the AVAudioSession setting or am I missing something?

I mean I had the same issue and had to resort to http://stackoverflow.com/questions/24595579/how-to-redirect-audio-to-speakers-in-the-apprtc-ios-example, which works fine but isn't the best way to go.

Best regards
