Run pavucontrol. In the playback tab  under the stream you are listening 
to there will be a box with the name of your  audio device. clicking on 
that gives a drop down ... select jack sink. Sound should return. Then go 
to the output devices tab and find jack sink. There is a square button 
with a checkmark in it to "set as fallback". clicking on this makes that 
the default.

In my case, I unload the PA alsa module and the PA udev module so that 
pulse only ever sees the jack sink and then run jack at session start.

In my opinion, Pulse has the front end jackd should have always had and 
jackd provides a stable backend that pulse should have always had.
