do you mean "no application at all" or is it a more limited set (e.g. 
hydrogen only)?

The warnings are not important.

what does "jack_lsp" return?

I suspect that this is an autoconnect issue. It's not really a 
jack/freebob issue, but is misbehavior of the application.

In case of hydrogen, try the following:
* click away the error dialogs
* go to file->preferences
* go to the "Audio System" tab
* unselect the "Connect to default output..." checkbox
* press ok
* restart hydrogen

Now go to qjackctl and manually connect the hydrogen ports to the 
soundcard ports.

This should work.

That's a respected attitude around here.
