Is there a way to change the playback device of a MMDevice?

 

I know there is a hacky way to change the DEFAULT playback device, but I only want to hear (for example, a input line coming from a turntable) to a specific  audio output.

Same way is done in this window 

 

Hope you can help me

to monitor an input you'd need to record sound from that input (WasapiIn) and play it to the output (WasapiOut).

Kind of a bit redundant :S

And what would be the process? I hope you can help me a bit because Im sort of lost in here:

 

var waveIn = new WasapiCapture(inputDevice);

var waveOut = new WasapiOut(outputDevice, Shared, true, 150);

//What object do I need to create to provide a IWaveProvider for it Init method of waveOut?

 

Hope you can help me with this

you can use the BufferedWaveProvider for this. When you recieve audio from the capture device, write it into the BufferedWaveProvider. The player can just read continually from BufferedWaveProvider.

Hi

I tested the BufferedWaveProvider and worked like a charm, but I facing a strange issue: now I hear the stream in 2 different output devices (speakers and headphones (headphones is my default playback device).

Any recommendation to really switch the monitoring device rather than just duplicate it?

You'd have to ask someone who knows the CoreAudio API really well. Perhaps there is a way of getting and setting that "Listen to this device" property.

I will search for a solution and I will post it here when I found it
