First: I setup qjackctl to *not* start jack, and indeed it isn't, at
least jack clients started up with qjackctl open, but jack not started,
complains that jack is not running.

Second: Firefox (let's take that as an example) uses the buildin
soundcard, and qjackctl/jack is using the firewire card.

If jack is running I'm of course not expecting non-jack apps to be able
to access the soundcard that jack is using, but this is not the case here...
