Sounds setting in Unity is not letting me to configure my bluetooth headset as output device, simply because it is not showing the settings of that device, but always show the settings for my default sound card.
sudo apt-get remove --purge alsa-base pulseaudio
sudo apt-get install alsa-base* indicator-sound* libcanberra-pulse* osspd* osspd-pulseaudio* pulseaudio* pulseaudio-module-bluetooth* pulseaudio-module-x11* unity-control-center* unity-control-center-signon* webaccounts-extension-common* xul-ext-webaccounts*
Please help!!! I can't afford myself to reinstall my whole OS right now.
As mention by Charles Green, installing/reinstalling pavucontrol solves it!
After that, I immediately wasn't able to use Unity's sound settings, but after a reboot I was able to.
Thanks!
