Unable to use Bluetooth on Ubuntu 14.04 64bit

  • 772

I recently had a need to do a clean reinstall of my machine and for the most part things are working ok. However when trying to connect my BT headset (Noga NG-55BT, generic BT headset) I am unable to get any audio sent to the device. It registers just fine and machine detect's it but that is as far as it goes.

I looked into similar issues on this and other sites tried all kind of things and no luck.

OS: Ubuntu 14.04 64bit (Unity desktop) Realteck WIFI ppa: ppa:hanipouspilot/rtlwifi
