I have a new Inspirion 15 with windows 10 and I have a problem connecting it via bluetooth to speakers (I tried different speakers, and it's the same problem with all of them). The laptop connects to the speakers, but the sound stutters constantly. I installed all the new drivers for audio and bluetooth but it doesn't help.
Plug headphones or speakers directly into the laptop audio out jack. Test audio. If the audio is clear and not stuttering, then the laptop audio driver is fine. The fault must lie with the bluetooth driver that Windows 10 is using. It would be helpful to know the specific bluetooth speakers you are testing and specific Inspiron 15 model.
