Bluetooth Audio driver issue (Avrcp Transport Adaptor ) Windows 10

Hello I just received my HP ENVY Desktop 795-00xx and have noticed that when I connect my Bluetooth speaker to my computer it causes it to freeze every so often and the audio is also out of sync with the media playback. I use this same speaker with my HP ENVY laptop and I have had none of these issues with it. I can see that there is some sort of error with the Adapter which doesn't seem fixable, just wondering if anyone knows if there is anything I can do to address this problem since the Bluetooth speaker is the only way I can really output any audio out of this computer other than headphones which is not very ideal for me.

This is my version of Windows and the Adapter that is not installed correctly. I have updated the Bluetoohth drivers using Windows Update and I have also installed the ones from the manufacturer (HP), but the problem persists.

Thanks in advance,

Carlos

Actually, it looks like I spoke too soon. Though there is less of a delay with the audio. Still experiencing a bit of freezing

My problem is the same as yours, delay and small cuts of sound. I think if that driver was installed correctly, those errors would be solved because I have another Asus PC with Windows 10 Pro that installs that driver correctly and the headphones work perfectly.

Hi,

Thank you for your reply,

Let us try to disable the absolute volume feature via a Registry key edit and check if it works fine.

Registry Key Edit Option:

o To Disable:

· Open an administrator privileged command prompt

  Select the search box in the taskbar, type cmd, right click to open as admin.

· Enter the following command:

  •  reg add HKLM\SYSTEM\ControlSet001\Control\Bluetooth\Audio\AVRCP\CT /v DisableAbsoluteVolume /t REG_DWORD /d 1 /f

o To Enable:

· Open an administrator privileged command prompt.

  Select the search box in the taskbar, type cmd, right click to open as admin.

· Enter the following command:

  • reg add HKLM\SYSTEM\ControlSet001\Control\Bluetooth\Audio\AVRCP\CT /v DisableAbsoluteVolume /t REG_DWORD /d 0 /f

Registry disclaimer: Important this section, method, or task contains steps that tell you how to modify the registry. However, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For added protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs.

I have disabled the absolute volume feature.

I have also unpaired the headphones which uninstalls the drivers that I marked in red.

I have returned to pair the headphones, the AVRCP is still not installed correctly and the problem with the sound persists.

Thanks,

Carlos
