Hi Mac (and others),

Yesterday, I tried this for myself and can confirm that the Alsa Jack
bridge is always enabled after a reboot even if you turn it off before
shutting down.

I had a quick look at the code to see which configuration files are
written, but ran out of time before I worked it out.

Hopefully Len who wrote the code will have the time soon to take a look
at it. In the mean time I will try and take another look and see if I
can find a workaround.

I submitted a bug to track it:
