How to send audio to iPhone loudspeaker instead of earspeaker?

sinosoidal

Hi,

I'm new to TAAE. One of the problems I have on iPhone is that it automatically changes the audio output to the earspeaker. How can I send the audio to the loudspeaker? This doesn't happen on the iPad because there is no earspeaker.

Thanks in advance,

Regards,

Nuno

Strange - does this happen in the TAAE sample app for you, @sinosoidal?

Michael, didn't tried the sample. I have coded directly on my app. What should I look for? My initialisation code is like this:

NSLog(@Initializing DRCAppDelegate);
self.audioController = [[AEAudioController alloc] initWithAudioDescription:[AEAudioController nonInterleaved16BitStereoAudioDescription] inputEnabled:NO];

    BOOL result = [_audioController start:&error];

    if (!result)
    {
        // Report error
        NSLog(@"There was an error while starting AE");
    }
    else
    {
        NSLog(@"AE Started");
    }

    NSString *category = AVAudioSessionCategoryPlayAndRecord;
    AVAudioSessionCategoryOptions options = AVAudioSessionCategoryOptionMixWithOthers;

    if (![[AVAudioSession sharedInstance] setCategory:category withOptions:options error:&error])
    {
        NSLog(@"Couldn't set audio session category: %@", error);
    }

    self.channel = [AEBlockChannel channelWithBlock:^(const AudioTimeStamp  *time, UInt32 frames, AudioBufferList *audio)
    {
        Q_UNUSED(time)

        if (DRCController::instance())
        {
            if (DRCController::instance()->synth())
            {
                //DRCController::instance()->synth()->process((float*)audio->mBuffers[0].mData, frames/2);
                DRCController::instance()->synth()->process((float*)audio->mBuffers[0].mData, (float*)audio->mBuffers[1].mData, frames);
            }
        }
    }];

    _channel.audioDescription = [AEAudioController nonInterleavedFloatStereoAudioDescription];
    _channel.channelIsMuted = NO;
    _channel.volume = 1 ;

    [_audioController addChannels:@[_channel]];

    /*
    self.audiobusController = [[ABAudiobusController alloc] initWithApiKey:@"MTQzODU5ODc5MyoqKkRSQyoqKkRSQy0xLjAuYXVkaW9idXM6Ly8=:SXpF6BxtD5Aw97zkqWu7dTC6jHo4RWljWsYigmNkiL5urPUOuM8Gfq9przySRQ5EN+HpNZlI0rDWGcMPBErkfu8syUTXvHyFfw/KnbTZgA+xd48pZlpT5S77ub/1HE9D"];
    self.audiobusController.connectionPanelPosition = ABConnectionPanelPositionLeft;

    ABSenderPort *sender = [[ABSenderPort alloc] initWithName:@"DRC-1 Output"
     title:NSLocalizedString(@"DRC-1 Output", @"")
     audioComponentDescription:(AudioComponentDescription) {
     .componentType = kAudioUnitType_RemoteInstrument,
     .componentSubType = 'drc1',
     .componentManufacturer = 'imgo' }];

    [_audiobusController addSenderPort:sender];

    _audioController.audiobusSenderPort = sender;

    [_audiobusController addObserver:self forKeyPath:@"connected" options:0 context:kAudiobusConnectedOrActiveMemberChanged];
    [_audiobusController addObserver:self forKeyPath:@"memberOfActiveAudiobusSession" options:0 context:kAudiobusConnectedOrActiveMemberChanged];
     */

Thanks,

I see you're interacting directly with AVAudioSession - I'd remove that stuff, as TAAE handles this for you, and you may be interfering with it.

Michael,

It was that! Thanks!
