I have Lubuntu 14.10 so I run ALSA instead of PulseAudio and I am not about to change it.
blueman-manager lets me detect my speaker as headphones but choosing
Setup-Audio Receiver(A2DP) results in error
The device has been successfully added but playback is impossible (nearly translated). Launching this manager from console complements error mentioned above with this output. I googled the problem around, but most of the information I found felt very, very outdated. So I thought that it would be safer to re-raise the issue here. Searching for
bluetooth in Synaptic results in Everything was here before, I only tried to install bluez-alsa, but it didn't change anything. Before going any further and randomly trying advices from those suspicious obsolete guides I halted and I'm here, waiting for your solutions
UPD: I looked into similar questions and tried this script which seemed simple and comprehensible. It printed same error that GUI applet did

UPD2: Installed an additional pile of useless packages (screenshot updated), still no effect
