Here is an in-depth guide on how to configure the Widcomm bluetooth driver stack for A2DP:

You will need to enable the "A2DP" bluetooth profile on your Windows machine for it to work properly, although Windows XP/Vista does not natively support it so you will need to install something like Broadcom Widcomm stack, here is a quick guide:

You do need to remove the Windows bluetooth stack first. This Microsoft KB article describes how to properly remove the standard bluetooth functionality that comes with Windows here:

The Widcomm bluetooth stack has support for many different profiles, including A2DP for streaming audio which is what you need.

If you don't feel like using Widcomm you can always use BlueSoleil which is a bit more user-friendly but it isn't free, here's their homepage:


Old News ;-)

help regarding audio streaming over Bluetooth - Multimedia - PDA

The curent bluetooth driver for A2DP routes it directly from your audio, so
there is no special code required when writing the MP3 piece. Basically
write the MP3 player, install the A2DP bluetooth driver and you are happily
streaming your music.

If you want to look at some existing A2DP hardware on the market check out
HP's Bluetooth headphones for the Ipaqs. It might be of some help, and it
does provide the A2DP driver (and bluetooth stack update) for several Ipaq

Of course your Laptop

will have to offer an A2DP service for the PDA to link
with if you pln on piping the audio over to it.

As for extended stacks, are you saying that you are using a video bluetooth
profile? Now that is interesting, but outside of some development work I
have never seen it on the streets. Stereo (A2DP) is just now becoming

What's the easiest way to stream audio from my laptop to a receiver

Ask the Editors Crave - CNET

I've read your reviews of headphones that use a USB dongle to stream any and all audio to it wirelessly. Do you know an affordable (less than $60) way to do this and send audio to a receiver? I have a line in port that I'd love to connect to some sort of device that could receive an audio stream from my laptop.

--Russell, New Jersey

Hey Russell,

I've actually been on the hunt for a cheap way to do the same exact thing in my apartment. Unfortunately, there's probably nothing that can do it for under $60. Back at my parent's house, I set them up with an Apple Airport Express (around $100) that allows you to wirelessly stream music from any network-connected computer running iTunes via the Airport's line-out jack.

If that's not something you'd be into, you may want to look at something like the Creative Labs Xmod Wireless Music System (which goes for around $100). It's not as easy as a USB dongle, but it should stream any and all sound coming from your computer.

Our editors really liked the Logitech Wireless Music System for PC but it looks like that device isn't manufactured anymore. However, I'm sure you can still find it on Amazon or eBay.

We also came across an Onkyo solution that looks like it'll do what you want, but it retails for $150.

Lastly, we don't usually point our readers into these murky waters, but we stumbled across a very suspect product that somehow completely satisfies every requirement you stipulated, including the price. If all else fails and you simply cannot spend the extra cash on what we recommend, head over to They've got a no-name USB transmitter/receiver that says it'll do exactly what you want. But please keep in mind, we've never tested it, we're not sure it works, and judging by the photo, they might just be sending you all the components in a plastic bag. If I haven't been clear, this is a total "try this at your own risk" lecture.

Good luck Russell!

Thank you for your question, I hope that you find the following answer useful.


Wireless audio streaming solutions are commercially available from several manufacturers, including Linksys. These solutions use the 802.11 wireless standard instead of the Bluetooth standard, due to the range and data-rate limitations of Bluetooth. With the 802.11 solutions, you can easily play your MP3 files through your home theater.


The Bluetooth standard supports a recommended maximum range of 10 meters, due to the 1 milliwatt transmission strength defined by the standard. The maximum data-rate possible in one direction is 721 kbps, assuming that there is no interference. Bluetooth operates in the unlicensed 2.45 GHz frequency spectrum, using spread-spectrum technology to reduce the impact of interference.

Because of this data-rate and limited range, the manufacturers of specialized streaming audio solutions have chosen not to go with Bluetooth. The intent for the manufacturers is to maximize the potential market while minimizing the support costs, so by choosing 802.11b and 802.11g as the wireless standard, they can take advantage of data-rates from 11 Mbps to 54 Mbps, and usable ranges from 150 feet to 1000 feet. 802.11b and g also operate in the 2.4 GHz band, but use discrete "channels".

The specialized solutions that they have come up with are represented by a device such as the Linksys Wireless-B Media Adapter. This device connects to your home theater using standard RCA cables (stereo audio and video or S-video). You will also need an 802.11b wireless network adapter such as the Linksys Wireless-B Notebook Adapter (WPC11) or USB adapter (either Linksys WUSB11 or WUSB12). Then, after installing a utility on your laptop, you can use the Media Adapter to remotely search through and play any MP3 file you have on the notebook computer. You can also use the Media Adapter to display any pictures that you have on the notebook, if you have a TV connected to the Media Adapter.

Since you state that you do not already have any Bluetooth devices, this makes an 802.11b-based solution even more viable. 802.11b networking devices are more readily available these days versus Bluetooth networking devices. Bluetooth is, more and more, being used only for "personal area networking" solutions such as mobile phone headsets, PDA synchronization, and simple computer communications.


Bluetooth CLASS2 Mini Adapter Plug-n-play 10 Range

Plug N' Play Perfection, February 1, 2009
By K. Ryan (Madison, MS USA) - See all my reviews
I plugged the Micro Innovations Bluetooth Adapter into my USB port and Microsoft Vista instantly recognized the device and in seconds it was ready to use. Now that's the way Plug N' Play was supposed to work. I've owned other brands of Bluetooth USB adapters and the adapters I owned required the manufacturer driver and I incurred problems. If you want a trouble free USB Bluetooth device with a 33 foot range, I recommend this device.

IOGear USB 2.1 Bluetooth Micro Adapter GBU421

out of 5 stars Full Review: IOGear vs. Cirago, November 1, 2008
By BOGY. (CT) - See all my reviews
Amazon Verified Purchase(What's this?)

I have purchased both the Cirago and this IOGear. Both work perfectly with Windows XP and Vista. The Bluetooth drivers auto load and it makes sharing files and pairing very easy. On your task bar will be a BT icon that you right click for a list of options. The IOGear claims to work with MAC but the Cirago doesn't. I don't have a MAC so I do not know if this is true or not (Sorry). The Cirago has a brighter blue light than the IOGear. Also, the IOGear is smaller (But not by much). Both are so small in size they can be left in the USB slot and not removed. The IOGear is easier to remove from the slot than the Cirago (it is the shape of the exposed area that determines this). Here is one other interesting thought. Take a look at the picture of the IOGear. When plugged into the USB the metal part slides all the way in so only the black plastic area is sticking out. That is nice, eh? The Cirago goes in the same but sticks out just a little more than the IOGear (Some metal exposed). However, both function perfectly with USB BT 2.0 and early versions 1.0 & 1.1! Both are backwards compatible. The range doesn't seem to be different - I have tested both from 20 feet and they work (Document sent to printer). You choose.

By Avid Reviewer (Florida) - See all my reviews
I just received one of these in the mail and it works like a charm. Its real tiny so you can just leave it connected. I'm running Vista and needed to download the drivers off their site to get it up and running. Once they were installed, it paired up with my Jawbone 2 right away. Now I can play Steam games using my bluetooth headset as well as experiment with Vista's voice recognition software.

4.0 out of 5 stars Great Product, July 16, 2006

By D. Mohammed "Dragonlord Warlock" (island earth) - See all my reviews
This product deserves a five, but since I only had it for a short time. I did not want to jump the gun. It connects greatly with my Plantronics 510 headset, my Palm TX and with my Razr phone; which pretty much is all the bluetooth enabled devices I currently own. It has made me wonder what else can I add to my system that supports bluetooth. So far I had no problems with it interfereing with my Wifi network, which is a good thing. I read that bluetooth can cause collisions when data is transmitted over a wifi network, as both wifi and bluetooth use the same frequency range, but while wifi listens before tansmitting, bluetooth does not. However, this is a bluetooth 2.0 device which suppose to work better within a Wifi network, however my other devices are not bluetooth 2. Yet everything works well.

Thus I can safely say this is a good product, and works flawlessly and safely in a mixed wireless environment.

IOGEAR USB Adapter with bluetooth Wireless Technology 2.0 Spec Class 1

1.0 out of 5 stars Does not work with A2DP stereo headphones as advertised, August 19, 2009
By Dane Powell (Austin, Texas USA) - See all my reviews
Beware- if you are buying this to use with devices supporting the A2DP protocol (stereo headsets such as the Motorola S9-HD), it does NOT support this protocol. Even if you install the WIDCOMM / Broadcom driver stack, which should support A2DP, the dongle itself does not. Oddly, you can sometimes get A2DP-based headsets to work, but only at distances of a few inches.

This is a well-documented problem if you search for "Broadcom 2045" (the chipset in this dongle) and "A2DP". Also, similar reviews of this specific dongle exist on other sites as well.
2.0 out of 5 stars doesn't work with everything, August 24, 2007
By SoR609
Read before you buy! I guess I forgot to do my research.
So far there is only one update on IOGear's website for the driver and none for the firmware. And I found out the hard way that they are needed.

Out of the box, I couldn't connect my Blackberry phone to my PC through this adapter as a remote audio gateway and the driver update solved the problem. So far so good.

Then my Motorola S9 headset came in and it didn't play the sound well. I tried a bunch of different things (reboot, different device settings etc.) and it started playing, but not for long. It started cutting out and became very choppy and eventually more silent more than it played music. I rebooted again and thought maybe it was Winamp and the way it uses directaudio so I tried WMP 11. No luck. Tried both programs on another PC and nothing.

So after few minutes of searching online, it seems that others had similar issues with their laptops based on the same/similar chipset. Those that were able to update their firmware and drivers eliminated their problems.

This could be a good device but it needs support.

Recommend buying Anycom 200 or 250. It seems they provide frequent updates.

Don't use the included driver, June 30, 2008

By Vincent Zinkus (Cape Coral, FL) - See all my reviews
Have had this product for about a year now, and it has worked flawlessly with my BB Pearl 8100, Plantronics Voyager 510, and Samsung P2 MP3 player. However...I DID NOT use the included driver and software, as they did not work with anything very well.

And Windows XP does not have a built-in driver for this device...except that it does, but doesn't know it. This device has a Broadcom chipset (BCM2045) in it, and XP has a builtin Broadcom driver (BCM2033) which are the same file; however, XP doesn't match the two up.

So you have to edit the bluetooth driver .ini file manually to make it work. Needless to say it is somewhat involved, so to find out how to make it work, just google search broadcom 2045 XP setup and you should find it.

This will enable XP"s bluetooth stack, which works very well. Oh, and while I have not tested range, it is nestled inside my computer, surrounded by cordless phones, routers, and other electronics, and can still communicate through several walls to my devices on the other side of the house. Hope this helps. Thanks.

Belkin F8T001

(Quick Bluetooth Operability, v1 not the one to get.

The Belkin F8T001 did what I wanted it to do, whichwas move images from my phone to my PC without pulling the MMC card. It found my phone, clear across the house! 100-meter range means I can drop pictures on my PC from my garage if I wanted. The software bundle is very, VERY short on documentation but big on function: everything works as advertised.

I'm withholding two stars for these reason, though. 1) the aforementioned lack of value in the documentation, and 2) the disappointment I have in not being able to browse my phone directly (would've been nice to pull *all* my pictures from the phone rather than pushing each one to the PC). This is largely due to Nokia's PC Suite not being configured correctly, but also the Byzantine manner in which you must configure Bluetooth to make it work.

Note that this adapter has two versions, v1 being the "flag antenna" version and v2 being the "silver bullet" version. Drivers for v1 are not very current, although is available for registered users.

In conclusion, while v2 might be a solid choice, I would recommend the Linksys USBBT100 <ASIN: B0000DZET4> over this adapter for first-timers.
