http://askubuntu.com – Is there a way to use the notebook as speaker for my smartphone? I linked them via Bluetooth and saw that the smartphone can be used as an input-Device for music and sound. You can see it here: My smartphone says that the laptop is linked as an Audio-System. If i play some music on the smartphone, it is recognized by the audio manager. You can see it in the picture, the bar is active and keep moving to the music. But i can't hear anything. How can i get this working? Oh i just forgot: I'm using Ubuntu 12.04 as 64bit on a Lenovo Y560 and the Smartphone has Android 2.3.6 Best Regards (HowTos)
