Hi there!
I have a Dell Latitude E7440. I recently purchased a Voxoa BTunes Bluetooth adapter for Bose QC25. When connected to the laptop, there is a noticeable background hiss while sound is playing. When no sound plays, there is no hiss.
However, when it is connected to my iPhone, there is no hiss while sound is playing. This leads me to believe that it is an issue with the laptop. I have upgraded my Bluetooth drivers, and I have had no success. I was hoping that somebody could help me out. I currently have the Realtek audio drivers installed, and i have tested it with the standard drivers, and the hiss is still present.
Any help is appreciated.. thanks!
