Bluetooth Stack in Windows Vista – A2DP (high quality stereo)

April 14th, 2008 admin Posted in Portable, Technology | 17 Comments »

A2DP or The Advanced Audio Distribution Profile is a Bluetooth profile that allows for the wireless transmission of stereo audio from an A2DP source (typically a phone or computer) to an A2DP receiver (a set of Bluetooth headphones or stereo system). A common misconception is that A2DP support is available on all Bluetooth 2.0 devices or EDR (Enhanced Data Rate), which is not the case, and that A2DP is only available on Bluetooth 2.0 devices, which is also not true. A2DP support can exist in older versions of Bluetooth.

Windows Vista doesn’t support A2DP out of the box either. But with help of other drivers from Broadcom’s (formally WIDCOMM), Vista can make use of A2DP Bluetooth stack.

Download Widcomm Bluetooth stack BTW 6.0.1.5300 for Windows Vista (.ZIP, 75MB)

First thing is uninstall all other Bluetooth drivers from the Device Manager. You’ll have to repair your devices again. Enter the passkey for your headphones (often 0000).

Also if your is supported by BlueSoleil it may well be worth trying.

Updated info: After installing the drivers and pairing the Bluetooth, you’ll have to make sure windows redirects the audio output to Bluetooth speaker and uses Bluetooth mic as input for audio applications. This is the same procedure for redirecting the HDTV audio also. 

From Control Panel > Hardware and Sound > Manage Audio Devices , make the bluetooth Speaker as default and Test. From now on, whenever the Bluetooth is paired, audio output and input will be redirected through bluetooth device. Same, implies for HDTV devices also.

    Hi there.

    I have recently bought a A2DP bluetooth speaker from Altec Lansing, and it connects perfectly with my SE K810i cell phone – so far so good!

    I have a Thinkpad T61 with Vista and would love to make the sound go from the laptop to the speaker. Vista identifies the device as a headset, but wont allow me to specify a passkey for the device. Vista says the devices doesnt support passkey exchange, and only allow me not to specify one – but then, eventhough paired, it cannot connect to the speaker. Have you any idea how to solve this problem?

    Thanks in advance!

    -Martin

    Martin,

    There should be 2 passkey options, one that something to the affect of providing a passkey from the manufacturer’s documentation. Put the “0000″ in there and it should pair up fine.

    Hi,

    I got the same problem as martin!
    got a philips 6100/00 bluetooth headset.

    I can only conect if its without a passkey, and it can find my headset, but i can’t use it..

    Got a Sitecom bluetooth usb adapter cn-510
    could it be that..?

    Hi Allan,

    it turned out that the bluetooth speaker was set to pairing mode when it came out of the box – so the first connection required another procedure than the first. After spending hours on installing different bluetooth stacks and firmware (stupid me) I found the solution in the device manual.

    This could be the same in your case, and after sharing my experience it turned out the another of my friends made the same mistake.

    Best regards,
    Martin

    Hi there,

    I have a new ThinkPad X200 Tablet with internal bluetooth 2.1 and Vista, which already included the Bluetooth Stereo Audio drivers. All works fine, huh?

    Yes it does, but it is about 50% – 60% of the volume of my old setup using Win XP and a variety of plug-in USB bluetooth dongles.

    Any idea how to get it back to a sensible volume? (I have adjusted all the obvious mixer settings.) Is there a Registry entry to tweek it up to the same level that Win XP used to use?

    Thanks – Andy

    Also, I get clicks and pops now – quite loud ones. As if it is turning on / off the audio between tracks.

    P.S. I am using a Sony Ericsson HBH-DS220 bluetooth headset, connected to a 200W car amplifier, and a whole stack of speakers and subwoofers…. So the CLICKS are LOUD!!

    Hi, after whole three days’ toil I’ve finally succeded to make function SE HBH-DS220 bluetooth headset with my HP 2510p Vista. Without this your help it would be completely impossible. As asked I needed to uninstall all other Bluetooth drivers from the Device Manager. So it works, anyway sound quality is not as perfect as expected to be. Do you have some advice to improve it?
