I know how to connect bluetooth headset to Ubuntu, so I can e.g. speak with Skype remotely.
Now I have the opposite question: How to turn Ubuntu into a sophisticated headset, that can record both input and output sound streams? I lack decent sound recording capabilities in my phone (Nokia 6310i) and I hope that I can help it a little with my Notebook.
Turning on A2DP sink and source is not enough for my Notebook to be visible as a remote Headset on the phone. I guess I need to turn on some another extra bluetooth protocol (like HFP profile).
I've discovered a utility [nohands][3] that promises to do just that, but it fails to build on the Ubuntu 14.04 and looks abandoned for 4 years.
After satisfying the dependencies (at least according to the ./configure) it fails to build:
