Connecting line in to bluetooth headset

Mar 17, 2012 at 12:55 PM

I just came across this API and worked my way through some of the tutorials. I have written a WPF app to play sound in my car. It takes the line in wave from a radio tuner and I want to route that via bluetooth to the car head unit.

If I use the onboard Windows 7 settings I cannot convince the line in- wave to be routed via bluetooth. No matter what I set it always uses the analog speaker output and I have some ground loop noise on that which explains why I would like to use bluetooth. For reasons I don't know the bluetooth headset output waveform is fixed at 48 kHz, 2 channels, 16 bit.

Is there an easy way to solve this, maybe with the waveIn, waveMixerStream32 and waveOut classes?

Thank you for your attention.

as long as you can identify which output device your bluetooth headset is, you should be able to play to it using WaveOut.
