hey vithun i have found solution for our samsung t42e soundbar i found on reddit.
Well, I spent most of the day running around in circles trying to get my audio fixed on my soundbar after I upgraded to Windows 11. After a lot of searching, I found the fix that ended up working for me. Someone posted on the Windows forums this fix, so I copied it. Hope it helps anyone else who needs it. I did exactly what they typed, restarted my computer, and it worked. FYI, when I saved the file, I just saved it to the desktop, and it worked fine.
Here I will give you a step to enable the ApTX protocol through the registry. You can try to modify the registry to see if "hands-free mode" reappears.
Steps:
Right click on the desktop and select New - Notepad Document
Copy and paste the following:
Windows Registry Editor Version 5.00[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\BthA2dp\Parameters]
"BluetoothAacEnable"=dword:00000000
Set the document save file type to "All files" and name it AtpTX.reg.
Then double-click on the reg file to import the registry key and restart your computer to see if the Bluetooth headset works with hands-free.
Disclaimer: Generally, modifying registry subkeys or work group is intended for advanced users, administrators, and IT Professionals. It can help fix some problems, however, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For further protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs
this fixed my problem
