I figured it would need an upgraded database. I got the upgrade done, but
it turns out that I could not run mythbackend as a service because the
official .service file assumes /usr/bin/mythbackend.  When I built from
source it put the executables in /usr/local/bin.  Once that was fixed it
ran.

Now to the problems I'm seeing.  I have a PBS channel that has an Audio
Disabled error on mythfrontend due to an initialization error.  All the
other channels work fine.  In Setup/audio the testing of the channels work
and I hear sound but the error popup says Invalid audio device.

If you can't duplicate, let me know and I'll see what logs I can dig up
