[Troubleshooting] Bluetooth Audio devices are loosing sound with Alienware 17 R3

Hello members,
Bluetooth Audio devices like headphones are loosing sound with my Alienware 17 R3. After connecting successfully, they are tend to loose sound after around 1 minute when in stereo mode but works moderately on handsfree mode. Even I can hear voices from Discord app but windows (OS) sounds get looses in a minute of connecting. Any solution for this?
Advance thanks!!
