Ubuntu bluetooth disabled(Qualcomm Atheros AR3012 Bluetooth 4.0 QS)

[jeremy31]

And did you try to change it to AR3012?

I didn't have to and I just installed 3.13.0-43 on this machine today

what do you mean? can you say it more easier? i'm really noob

So far, what has worked for me, in terminal

echo "blacklist ath3k" | sudo tee /etc/modprobe.d/ath3k.conf

Then edit rc.local

gksudo gedit /etc/rc.local

Now just above the line that says

exit 0

put

modprobe ath3k

save, exit program and reboot

This seems to be very similar to my Bluetooth headset problem. Would you please advice on blacklisting and modprobing for I really don't know how to do it?

What is the result of

lspci -nnk | grep 280; lsusb; uname -a; lsmod | grep bluetooth; dmesg | grep -i firmware

Are you using Blueman? There is a known bug in it that unloads module-bluetooth-discover and you need to load it for audio devices to work with

sudo pactl load-module module-bluetooth-discover
