This problem is regarding Bluetooth/Alsa/PulseAudio on Ubuntu 13.10 (Linux Mint 16 Petra). Per AskUbuntu threads at http://goo.gl/ITef0v, http://goo.gl/GdylZk, and http://goo.gl/Vb3Uz4 (among other forum threads I've found) -- I cannot get A2DP bluetooth working at all. For starters, the only way my Bluetooth device/adapter will even show up on my computer (so that I can "Scan" for bluetooth devices) is by running this script http://goo.gl/wQFJ6Q. After my adapter shows up, I can then scan and connect to my Bluetooth headset (RFMAB-2 by RocketFish). My Bluetooth adapter is Qualcomm Atheros AR9462 Wireless Network Adapter with built-in Bluetooth. After connecting to the headset, I am able to see services "Input", "Headset", and "Audio". I am able to connect to "Headset" and "Audio", however it gives me Mono sound and does not let me change profile to A2DP (high quality) -- instead it says "Failed to change profile to A2DP". Per the earlier linked AskUbuntu threads, I've tried changing my `/etc/bluetooth/audio.conf` file in every possible way to try to get this to work -- but unfortunately every time I change it and restart bluetooth, my sound manager seems to freeze up and crash, and no matter if I do `pulseaudio-k` or `sudo alsa force-reload` or `sudo killall pulseaudio` or `sudo pkill pulseaudio`; the only way for my laptop's speakers even to start working again is if I completely restart my computer (otherwise Sound Manager doesn't display any devices at all).
