A2DP Toggle


A2DP Freeware tool

The devices that support A2DP (most wm6.0 bluetooth devices), come with 2 audio drivers installed:

1) The "Audio Output" Driver (supported since ppc 2002)
2) The "Bluetooth Advanced Audio Output" Driver, that is responsible of sending audio data over a L2CAP Bluetooth connection, as per A2DP protocol

When the user connects a Stereo A2DP headset, and selects the "Wireless Stereo" profile, the Bluetooth Adv. Audio Output becomes the nr. 1 audio output route, and is indexed as the First audio driver. Any application will output sound by using that driver.

The problem is that sometimes we are already listening to audio in the device's speakers, and then suddenly we want to switch the output to our a2dp headsets - this is sometimes problematic, as the First audio driver changes from "Audio Output" to "Bluetooth Adv. Audio Output" and the applications currently playing audio need to be restarted.

For such issues, I have provided a tool, as freeware, that will install as a today plugin and offer the user the possibility of instantly switching the audio between Device Speaker and A2DP Stereo Headset.

It is designed for WM6.0, Microsoft Bluetooth stack, please download it and let me know how it works for you. There are some more modifications that will be done, so this is only Beta-1
