I want to send audio via bluetooth to an android phone - kubuntu 14.04

Solution 1:

I think you misunderstood what SoundAbout is - its not an A2DP profile for your android bluetooth stack - its an audio router that allows you to configure how audio generated in the android device is routed, very similar to what pulseaudio does (possibly it uses pulseaudio?).

What you want is not possible with stock android, because the Bluetooth stack on Android does not support the A2DP sink profile. See this question for further explenation on that and how to create an application that enables bluetooth A2DP sink.

You might get ahead more by replacing the default Android bluetooth stack with the bluez stack used on modern Linux distribution, though it does require replacing the kernel which you can only do if you have a rooted or customized device. see here for details.

Solution 2:

Have you considered setting up a DLNA server instead?

Currently, I use MiniDLNA to run a media server that can stream music to devices that can use DLNA. There are apps for Android that provide DLNA clients, like UPnPlay.

MiniDLNA is now called ReadyMedia, but the software is still called minidlna(d). It's very easy to set up through a config file.
