How to stream audio from microphone to speaker?

like below fixes the issue I went about solving this problem by extending the MediaStreamSource class with a class that used the microphone to provide samples to the MediaElement Player.
If there's any demand for this block of code I will happily post it somewhere. For now, here's a code snippet to help you out if you're trying to do the same thing:
// Provides audio samples from AudioSampleProvider property.
//  (MediaStreamType parameter will always equal Audio.)
protected override void GetSampleAsync(MediaStreamType mediaStreamType)
{
    // start the microphone capture if it's not started yet
    if (microphone.State == MicrophoneState.Stopped)
    {
        microphone.Start();
    }
}

// gets called back when the microphone's buffer is ready
private void microphone_BufferReady(object sender, EventArgs e)
{
    // Retrieve audio data
    microphone.GetData(buffer);

    // Reset MemoryStream object
    memoryStream.Seek(0, SeekOrigin.Begin);

    // Write the newly acquired data into the memory stream
    memoryStream.Write(buffer, 0, buffer.Length);

    // Send out the sample
    ReportGetSampleCompleted(new MediaStreamSample(mediaStreamDescription,
                                                    memoryStream,
                                                    0,
                                                    buffer.Length,
                                                    0, 
                                                    mediaSampleAttributes));
}

Record audio from microphone and speaker in C#

seems to work fine Probably the easiest approach is for you to save both to separate files, and then use the MixingSampleProvider to mix them together after recording. It will also be easiest if both are recorded in the same wave format (sample rate, bit depth, channel count).

With these it helps You can still use MPVolumeView with IONIC as plugin, you just need to control UITouchUpInside through code.
Check this if helps.
- (void) currentOutputs:(CDVInvokedUrlCommand*)command {

    if(!mpVolumeView){
        mpVolumeView = [[MPVolumeView alloc] initWithFrame:CGRectZero];
        mpVolumeView.showsVolumeSlider = FALSE;
        [self.webView.superview addSubview:mpVolumeView];
        [mpVolumeView setAlpha:0.01];
    }

    UIButton* btn = nil;
    for (UIView *view in [mpVolumeView subviews]){
        if ([view.class.description isEqualToString:@"MPButton"]){
            btn = (UIButton*)view;
            break;
        }
    }

    if(btn){
        [btn sendActionsForControlEvents:UIControlEventTouchUpInside];
    }
}
