I have an MSI GE75 with intel chip, realtek speakers. Tried all the fixes I can read on forum, but no sound from speakers. Audio jack has sound. Bluetooth sees my Beats earbuds, but will not connect and produce sound, just says "not set up". I have deleted and reinstalled ubuntu, also updated the hardware (via windows updates etc.) but these two issues persist regardless of attempted fix. In PAVU Controller window, the Built in analog stereo speakers show up, and the sound bar moves back and forth as if playing sound when I'm running a youtube, but no output from speakers.
