Registry edit to enable A2DP audio while playing video on Windows Phone 7

November 19, 2011 | By Surur

2-26-07-dr-bt21g A repeated annoyance of some Windows Phone 7 owners is that when using A2DP sound over Bluetooth, this will be disabled when playing video.

Of course the reason for this is somewhat understandable – when decoding video, transcoding sound to the A2DP audio codec takes processor cycles which then lead to sound dropping out or low frame rate for video.

If however you want to take your chances and have an Interop unlocked device or a device with a built-in registry editor like some LG ones, Fabcal has a simple registry edit which will fix the issue.

With your unlocked handset and WP7 root tools or other registry editor, edit:

HKLM\Software\Microsoft\Zune\Playback\Video\A2DP\CapsSet1

Change dword value DisableA2DPPLayback from 1 to 0

Reboot immediately afterward and enjoy Bluetooth Stereo Audio playback while watching video.

Note that as the Bluetooth antenna is often the same as the WIFI antenna they can interfere, making the solution better for playing local content than streaming content from the internet.

Utility offers super-easy A2DP connection

July 27, 2009 | By Surur

The problem with Bluetooth A2DP (sometimes referred to as Stereo Bluetooth or Wireless Stereo) is that it is not well implemented by many accessory manufacturers. They forget simple things like that the user wants the A2DP to connect when the Bluetooth connection is established. Well xda-developers user xiaojin1985 has solved the problem with a very simple utility: AutoA2DP.

AutoA2DP works how you would expect it to: when your Bluetooth device is connected, AutoA2DP kicks into action and starts up your wireless stereo connection automatically! It’s an extremely small utility and does not consume any memory except when toggling the A2DP state.

I have found this utility extremely useful and in fact use it every day (and every time I get into my car). But I found the installation process a little clunky. So I’ve written up a .cab file with automatic setup. Now it’s as simple as possible to install: just run the .cab file. Easy!

1/8″ headset jack be damned, who needs it when you have A2DP?

AutoA2DP can be downloaded from my website here with original xda-developers post here.

Bluestarter – new bluetooth automation answers many prayers

January 5, 2009 | By Surur

Windows Mobile 6.1 has a pretty good bluetooth stack, but unfortunately to access many functions require a trip to the bluetooth settings page. Examples where manual activation is required is Activesync via bluetooth and activating A2DP with some bluetooth stereo receivers.

Bluestarter finally provides an easy way to detect the presence of bluetooth devices in the environment, and allows one to act on the presence of these devices by running an application with specified parameters. The software can be set to run at regular intervals or only when the device is switched on from being suspended.

Examples of how the software can be used is to detect the presence of a bluetooth A2D receiver and run the excellent Teksoft A2DP toggle, which will automatically make an A2DP connection.

A2DPToggle updated to version 1.1

October 19, 2008 | By Surur

Most consumer A2DP headphones connect automatically when activated, but some don’t, and for those, connecting to them is a laborious process, involving a trip to the connection manager, bluetooth settings and another menu after that.

A2DPToggle simplifies that process greatly. It comes as a today screen plug-in, with large finger-friendly buttons (optional), and allows one to easily direct audio output from the speaker to A2DP, and phone calls from the headset to speakerphone.

The software is also scriptable, meaning for simple toggling of the soundpath one does not need to give up the any today screen space. The app can in this way also be mapped to a button.

The software now also supports Windows Mobile Standard devices.

HTC Touch Pro (and probably Diamond) users should be warned that the app appears to cause reboots when used with TouchFlo3D. Hopefully this issue will soon be fixed.

Download A2DPToggle from Teksoft here.
