that the versions of pulseaudio from the LAU distribution were fully
aware of Jack, and they
have proved to work in most cases.
For the record, the versions of pulseaudio modules installed are:
you need module-jackdbus-detect. the package is pulseaudio-module-jack
in debian/ubuntu. You also need to use jackd2 rather than jackd1.

Installed that, but still no sound. Shut down Jackd and it bursts into
sound.
Tried to restart Jack but it fails:

process 2296 is, of course pulseaudio:
bill 2296 1.1 0.0 861316 8004 ? S<l Sep27 12:34
/usr/bin/pulseaudio --start --log-target=syslog
This was after a reboot of system.
Ran pacmd list-modules which showed module-jackdbus-detect presnt but
not module-jack-sink or module-jack-source.
confirmed that I'm running jackd2 not jackd1:
$ dpkg -S /usr/bin/jackdbus
jackd2: /usr/bin/jackdbus
When does pulseaudio use module-jackbus-detect to check if jack is
running? Do I need to start jack
before pulseaudio?
Tried pacmd load-module module-jack-source and module-jack-sink. They
them show up in pacmd list-modules
but still totem hangs when started.
