The app doesn't seem to work for me. I just get "Speaker activated" whenever I press the icon. I tried running switch.sh from the terminal and got:

button.state.value = true (bool)
Speaker activated
my euid: 0
my egid: 0
method return sender=:1.7 -> dest=:1.129 reply_serial=2
uint32 1

Any ideas?

<UPDATE>

I ran "/opt/headphonefix/switcher headphone" as root and that seems to have put it into a state where it started working. I can now switch between headset and speaker using the icon.
