Can anyone confirm if this solution from the Linux mint forums works?

"Step-by-step solution Open new terminal (ctrl+alt+t) and type as follows:

mkdir ~/tmp
cd ~/tmp
git clone https://github.com/alinefr/rtbth.git
cd rtbth
make
sudo make install
sudo cp -r ~/rtbth /usr/src/rtbth-3.9.3
sudo dkms install rtbth/3.9.3
sudo nano /etc/modules
Add there "rtbth" at the end, then ctrl+o and ENTER (to save the file) and ctrl+x to close the editor
Reboot"
