Xperia Z2 :: No Sound From Bluetooth Player In Laptop After Streaming Music From Phone

When I am streaming a music on my XPERIA Z2  phone using THROW option onto my HP laptop, immediately xperia z2 bluetooth player pops up in my laptop showing progress of music but sound does not come from the player that is frustrating because everything with this throw option is ok except this sound issue.

I thought there might be some issue with my laptop so I tried my phone THROW option with other laptop also, there also  the  same problem is occurring. Other android phones like Lenovo, MI1s, even they do not have this THROW option, this problem is not occurring when I am streaming music from these phone onto my Laptop having simply turned on bluetooth in these phones.
