Windows 10 Does Not Allow to Use LG Sound Bar as Output Speaker

Problem & Solution 

If you have an LG soundbar, you may encountered a problem when you tried to make a connection. I have an LG NB2540 soundbar. Windows 10 can easly connect to this device but when I want to listen to music, I can not hear any sound from this soundbar. I still hear it from my laptop's internal speaker. Last year, I have found a solution on Microsoft's Community. I have used my soundbar happily until now. Recently, I needed to do a fresh install of windows. So I needed to solve this problem again.

The solution is very easy. 

1. Remove LG soundbar from bluetooth devices section.
2. Press start menu on Windows.
3. Write "command prompt".
4. Click "Run as administrator".
5. When it opens, write this command without qoutes and press enter:
• "reg add HKLM\SYSTEM\ControlSet001\Control\Bluetooth\Audio\AVRCP\CT /v DisableAbsoluteVolume /t REG_DWORD /d 1 /f"
6. Add again on bluetooth devices section.
7. Well done!
