Hey Paul,
Thank you for your response,
None of the above assisted me,
This is not a sound problem,my sounds works fine in my computer.
The Bluetooth connection working well in other independent devices, Both from my PC and my Android phone.
I do not think it is error with the Bluetooth connection because I can make calls from the PC and receive notification on a new incoming call,
I have also rested all the Bluetooth settings just to make sure and it didn't help.
So I suspect there is bug on the app on the PC.
