Yesterday I purchased a Bluetooth USB adapter(Startech.com USB to Bluetooth 4.0 Adapter-10m Class2) and followed the instructions to install driver etc. However when I tried to use a pair of wireless earbuds(Skullcandy JIB Wireless: product code: MRJW1474065) the sound from my music file on PC resonates from the PC speakers, not from earbuds even though the speaker icon in the taskbar has an "x" on indicating that the pc speakers are muted. When I fo to device manager Bluetooth appears as being connected . If I then go to Control Panel>Sounds and select "Headset" or "Earphones" it doesn't solve the problem. For some reason, the pc speakers are not being bypassed and going to the earbuds. I have done the installation twice already.
