Hi!
I'm writing, becasue I recently have a problem that I think is closely related to JACK.
A few days ago, suddenly I was unable to play or record anything.
I found out that I can use my soundcards in Ardour only if I use ALSA as a backend - not JACK.
Running JACK with 3 different audio interfaces everytime spawns 32 in / 32 out channels in the "System" JACK hardware clients - and none of that works.
I thought there's a problem with my system installation, but the same problem occured when I booted up an AV Linux LiveCD - and that really confused me.
I'd like to invite you to take a look.
