Bluetooth not working properly since windows update

greedy123 · 10 Jul 2017 at 08:35

I've got a set of bluetooth headphones connected via a USB bluetooth dongle (EkoBuy Bluetooth 4.0 - top seller on the jungle) on my desktop. They worked perfectly up until windows 10 did an update this week. Now when using the headphones, the sound drops constantly to give a stuttering effect.

I can't find out what is causing it. Nothing else has changed apart from the windows update.

The headphones connect to the PC fine every time I turn them on and they do play music at full quality. They just drop constantly. I've tested the headphones with my iphone and the work perfectly still, it's just with the PC. I've tried repairing the headphones with the PC but it didn't fix it.

The USB dongle is literally 30 cm from the headphones with a direct line of sight so there's no possible interference, and as I said, it worked perfectly before.

The windows update did other annoying things such as re-enabling every disabled sound device, switching my monitor colour profiles around... but that's by the by.

I should clarify, the update windows did was called "feature update to Windows 10, version 1703"

Any ideas?

Thanks for the suggestion. I tried this but it says the best drivers for my device are already installed.

Hi jpaul, really didn't follow any of that haha. I have no idea what protocol it is trying to use! The headphones are "Bose Quiet Comfort 35" if that helps?

So in device manager this is what I'm seeing.

The 3 devices listed under bluetooth - the Alpha one is my headphones. The Bluetooth Radios - CSR Bluetooth Radio is my bluetooth dongle. The drivers are up to date as previously mentioned. The hardware ID is "{473a6b1d-3407-400e-b91a-f991c5a39dc3}\CsrBtPort".

I've tried right clicking the device and installing it but that didn't help, the audio is still stuttering.

Thanks again for replying jpaul.

I uninstalled and deleted the drivers then restarted. I've plugged the device back in and now I'm seeing this in the device manager:

When I click update drivers I get:

I'm now looking for a manual install for the driver. Watch this space!

I've found the CD which came with the device. I used it to uninstall the CSR Harmony wireless stack software and then re-install it. Install worked and drivers reinstalled and device now appears under bluetooth radio once again. Still got the same stuttering problem though sadly. Hasn't had any effect.

Regarding your bit about quality, I've never had an issue with the headphones before this week and I've been using them 8 months now. It's only since the recent windows update that this problem has been happening. The quality has been perfect up until now, no matter what source was playing through them.

Is it worth buying a different bluetooth device to try?

I did uninstall CSR. God knows what microsoft have done!

I've ordered a bluetooth device with a broadcom chipset. Will post again once that arrives and I've tested it. Thanks for you help!

New one arrived today. It's working perfectly so far. Thanks for all the help
