How can I tell if Bluetooth audio is using lossless AptX coded on my Windows 10? My computer - Lenovo T430s - is connected to a Philips AEA2700 receiver.

Second the software. Jump to content Sign In. There seems to still be no good work around for the crappy CSR /Cambridge Silicon Radio Bluetooth dongles ie eBay Bluetooth dongles. CSR Harmony Wireless Software Stack is a software program developed by Cambridge Silicon Radio Limited. The most common release is 2.1.63.0, with over 98% of all installations currently using this version. It's a connectivity software that enables a seamless wireless experience.CSR Harmony enables PC Bluetooth profiles, and the new Bluetooth low energy profiles designed for health and fitness, mice and keyboards, and other PC accessories.CSR Harmony is an integral element of CSR’s Connectivity Platform for PCs and is based on CSR Synergy and BlueCore Host Stack (BCHS).

First of all, your bluetooth audio receiver (Philips AEA2700) supports decoding aptX. That's listed in its specification.

Then it comes to the transmitter. AFAIK there are two types of transmitter for bluetooth audio.

The first type is a USB audio class device (i.e. a USB sound card) with hardware codec. Examples are the ones from Creative, such as BT-W2.

For this type of transmitter, you can safely assume that it will automatically use the 'best' codec (i.e. aptX Low-Latency > aptX > SBC) available on both itself and the receiver. And I don't suppose you have ways other than checking its specification to know whether aptX is available.

The second type is a general bluetooth transmitter that supports the A2DP profile. The ones that are equipped in laptops are pretty much always of this type.

This type of transmitter usually relies on software codec(s), which are provided its driver / software stack, such as CSR Harmony.

Take CSR Harmony as an example, when it is used to connect to a aptX-capable receiver, an aptX logo with text such as 'You are now connected to an aptX-enabled headset' will pop up for a while.

It appears to me that CSR Harmony has been discontinued though. If true, one of the reasons could be the fact that Windows 10 has aptX codec built in, according to this. I have yet to notice any other indication that aptX will be used if you use the Windows-builtin bluetooth driver / stack though.

P.S. aptX is NOT a lossless codec.

My LG HBS-730 headset supports aptX and it has a indirect indication to tell whether the headset is connected with aptX codec. Just press and hold the volume up and down buttons simultaneously for 1 second, this is supposed to switch EQs, but has no effect if aptX is working, although you can still hear the beep sound.

Using this method, I found that my regular Intel Bluetooth adapter in Skull Canyon NUC on Windows 10 is actually connected to my headset with aptX codec.

I've no idea whether this has restriction on the Bluetooth adapter hardware, but the built-in adapter of NUC is such a common chipset which is widely used in most Windows laptops.

I have the same problem, there is no indication of aptX.Here is my work around.Watching youtube video, e.g. drummer, piano...If video/audio delay is minimal, aptX is working.Is there a visible difference between audio and video, then aptX is off.My results:

LG G4 + Philips AEA2700 = aptX ON!

It's an old thread, but the situation hasn't changed much since then. So here you go.

I created an application that displays CODEC information (device capability and the OS selection). It's still in beta, but if you're interested, you can download from the following site: https://www.bluetoothgoodies.com/tweaker/

There are two requirements to have the AptX codec working. First, you must have a bluetooth driver of Windows 10 supporting AptX codec from Lenovo company.Second, your Philips AEA2700 receiver can support the AptX codec. You can tell from the specification of the receiver, or see if there is a AptX mark on the receiver or not.

If there is no AptX mark, then your receiver is not support the AptX codec.If Lenovo company does not provide the bluetooth driver supporting AptX codec, then the AptX codec can not work. Only if these two requirements are meeting, you can hear music through the AptX codec. If one of them is missing, you can not.

So recently I have been trying various things to get Bluetooth to work.
I have found out that my bluetooth device is a generic CSR Bluetooth device.
CSR, as I read in researching them, powers the WiFi (even my computer WiFi, I think is CSR) and Bluetooth of many devices, including windows products right?
Well my Windows Vista Business (SP2) cannot ever find a driver for my BT dongle.
I have tried 'Microsoft Fix It - Devices' it did fix the problem the first time but the next time I plugged in my dongle it stopped working again. I have tried 3rd party software but due to the driver problem, it never works.
I have searched the CSR website but I could not find any related software.
The software, I tried, came with the dongle, its called 'BlueSoliel IVT 2.7.0.13'
I have also tried newer versions of BlueSoliel but it all led back to the driver problems I got.
The BT dongle wouldn't work because windows cannot find a driver.
Another thing is compatibility issues. My dongles is made for Vista, and had the vista logo on its packaging. I have been through many Microsoft answers and literally none of them are my exact problem. My problem, as I've mentioned is that windows fails to find drivers for a Generic CSR Bluetooth dongle.
Please help me if you can. I have been to a lot of trouble trying to make my Bluetooth dongle work.
I would think that windows would be able to use a CSR Bluetooth device perfectly without a problem.
Anyway, If you can please, find me the driver/s. If I could find the correct drivers for my computer Bluetooth would work fine.
