I have a Sennheiser HD 4.4, I can connect it to my 14.04 Ubuntu. I also set the configuration on A2DP using
pavucontrol and it works for a while. But after like two minutes everything which plays any sound freezes and the headphone itself is removed from the output sinks and also the connection bar in the Bluetooth setting turns off as in the picture posted! As soon as I disconnect the headphones, YouTube will start working normally
This will be fixed if I restart the computer and do the pairing process from the beginning. But after several minutes it will go crazy again.
As requested this is the output of
lspci -knn | grep Net -A3; lsusb after the problem occurred:
