Starting with Windows 10 May 2020 Update, the ability to stream music from your phone to your PC’s speakers is once again available. If you’ve already upgraded to Windows 10 version 2004, you can now stream music from your Android, iPhone and feature phone to your PC via Bluetooth.
In other words, you can pair your mobile device to the PC wirelessly with Bluetooth and then stream music. There are no limitations and you can also stream audio playing within Chrome, YouTube, or built-in music player on your desktop or laptop’s audio point such as the speakers and wired headphones.
The feature uses Bluetooth A2DP Sink, which was previously present on Windows 7 in the Control Panel and third-party apps. As Intel confirmed, Bluetooth A2DP sink was left behind when Windows 8 was released to mainstream users.
November 2019 Update (version 1909) or older versions are also limited to A2DP source role, which only works the other way around. The ‘sink’ role, which enables the ability to stream music from your mobile device to your PC speaker, is not available.
Last month, Microsoft penned a document that confirmed Windows 10 version 2004 reintroduces support for “remote audio sources” and you can configure your PC to behave like a Bluetooth speaker.
However, Microsoft says that you’ll need an app to manage the Bluetooth A2DP sink function and the feature is currently not available via system settings.
Developer Mark Smirnov told us that he has created an easy-to-use Bluetooth A2DP sink app and it allows you to listen to music from your phone on your PC speakers or wired headphones.
How to stream phone music to your PC speakers
To stream music from your mobile device to your Windows 10 PC’s speakers, follow these steps:
- Upgrade to May 2020 Update (version 2004).
- Enable Bluetooth on your PC and phone.
- Open Windows 10 Settings > Devices > Bluetooth & other devices.
- Click on ‘Add Bluetooth or other device’ and select ‘Bluetooth’.
- Choose the phone and follow additional instructions, and pair the device.
- Select Done and your phone will appear in the Bluetooth & other devices page.
- Download and install ‘Bluetooth Audio Receiver’ from Microsoft Store.
- In the Bluetooth Audio Receiver app, select your device.
- Click on ‘Open connection’ and you can now stream music from phone to PC speakers.
If you want to end the session, click on the ‘Close connection’ button within the application.
The app only allows you to stream media content from your phone to PC speakers and you cannot use it to make or receive calls.
If you want to manage calls via Bluetooth, you can try Microsoft’s Your Phone app or Dell Mobile Connect.
Windows 10 has a Bluetooth Stack included and recognizes most Bluetooth Sticks without any problems. However, while Windows does support A2DP, it does not act as a sink and therefore, you cannot e.g. stream Audio from Android to the Computer, which is what I want.
The manufacturer of my BT Stick does not provide any Windows 10 Drivers, since Microsoft does this. I tried the older software, which can act as A2DP sink, but it has a memory leak that crashes my PC after longer sessions of listening to music, which is basically every day (I listen to music while programming/working). (Basically I can watch the non-pooled Kernel memory go up by the second when listening to music and can make it stop by stopping the music)
So my question is, is there any alternative, universal driver I can use that can act as said sink to receive Audio from my Phone on my PC?

TLDR
If you are running Windows 10 2004 or newer (which you should), download and run the excellent open-source program AudioPlaybackConnector and you’re good to go.

Microsoft is re-adding A2DP sink support to Windows 10 in version 2004.
In the codebase of Windows 10 preview builds, references to Bluetooth’s A2DP Sink feature has been spotted again, suggesting that the feature is making a comeback.
https://www.windowslatest.com/2020/01/26/windows-10-a2dp-sink-bluetooth-support/
However, while Windows 10 BT driver did implement A2DP Sink protocol, you still need an application to explicitly open the connection to your device. Without said application, audio from your device will not be piped to your PC, despite the device might be shown as «ready» in sound control panel.

This answer originally recommended a UWP application — Bluetooth Audio Receiver to open the connection. However it had several problems — notably, its window has to be kept open and cannot be minimised to the notification area. It is also not open-source, and only available from Microsoft Store.
Per @mishamosher’s advice (thank you), I now recommend AudioPlaybackConnector by Richard Yu @ysc3839. It is open-source and very minimalistic. It also has a more familiar look and feel to the Settings App, which is nice IMO.
After opening the connection successfully, your A2DP source device should show some kind of Bluetooth status. Here’s Android for example:

It seems like Microsoft has disabled A2DP sink capabilities since Window 8,
or it just doesn’t work anymore.
You could try to download and update the audio driver with software supplied
by the manufacturer of your Bluetooth card/chip.
If that doesn’t help, you could replace the Microsoft Bluetooth Stack with a
third-party product, such as :
- BlueSoleil Bluetooth Stack
($27.99) - Toshiba Bluetooth Stack (for the right hardware)
- WIDCOMM/Broadcom Bluetooth Software (for the right hardware)
[EDIT]
To summarize our discussion below:
- The Broadcom drivers have the A2DP sink but suffer from a serious memory leak (which has been the case for the last decade), while
- Microsoft’s A2DP sink capabilities are not functional.
So the only options I can think of are:
- Try BlueSoleil and buy if it fixes the problem and the free version is too restrictive.
-
Disable/enable your network adapter whenever a slow-down occurs, in the hope
that this will reinitialize the memory.
This can be done via a script run as admin:
netsh interface set interface "network adapter name" admin=disable
netsh interface set interface "network adapter name" admin=enable -
Replace your network adapter with a non-Broadcom card.

Sure, not for everybody, but usable:
- Use Linux in VirtualBox and capture bluetooth device. I have Kubuntu 16.04 as a guest on Win 10 and Intel BT and this setup works. (Or use old Win 7 as guest. It had this A2DP sink feature. But not tested by me. I used Kubuntu, because I use it at work on Win host.) It worked «automagically» after pairing in «System settings — Bluetooth».

I had this problem with a £3.50 ebay dongle, for which I had lost the driver CD. As stated by others, Windows 10 default drivers don’t support A2DP sink mode.
The CSR 4.0 bluetooth Harmony software stack solved it for me.

Windows 10 May 2020 update restored A2DP SINK support. I found a tutorial which I am linking down below.
https://techcentaur.blogspot.com/2020/05/how-to-use-a2dp-sink-on-windows-10-2004.html
From the link
WHAT DO I NEED?
- WINDOWS 10 with May 2020 update, build 2004
(publicly available now/get it from official websites)- Compatible PC with compatible Bluetooth.
(Google for your adapter)
3.Bluetooth receiver app from Microsoft store.SO HOW TO DO IT?
So you downloaded the update what now ? Your have Bluetooth. But how to get it to work?
- Open Bluetooth settings in windows 10
- Turn Bluetooth on
- Add Android Device.
- Open the app
- Click on connected device
- Click on open connection.
Now you have successfully connected device as A2DP source/sink.
Now you can use this for recording internal audio or to listen music, there are many more aspects to this as this is useful in can music systems also and some smart devices like Alexa-Dot need this feature for better connectivity with Windows.

If you have Broadcom Bluetooth Chipset, such as BCM20702, you can try the BTW stack from Broadcom: https://www.iogear.com/support/dm/driver/GBU421 (ver. 12.0.0.9980). I’m guessing it implements entire or the most part of the BT stack with its own kernel drivers. Later drivers (ver. 12.0.1+) seems to utilize the windows BT stack and does not ship it’s own kernel drivers (Only a very small helper kernel driver is loaded, presumably in charge of firmware loading).
I have success with iPhone 5c+BCM20702+Windows 10 x64 1809, where both A2DP and AVRCP works (There’ll be a popup window showing which song is playing with other control buttons). You can even use your computer keyboard as the input device for your smart phone.
FYI: Device needs to be repaired after the driver is installed, you have to «forget» your computer from iOS settings to start the authentication process again.
