Well, something kept dying after about 20 seconds, and it wasn't JACK. I guess that doesn't meant it was PA, might have been some application or the KDE sound system (most likely). I didnt spent too much time with it as I didn't need it to work.

That's your opinion. OTOH it's my necessity. FFADO makes it possible; ALSA never came close.

For pure desktop use, for 99% of people no... for me, if this was my only PC then I'd need to make it work, but only because the primary function of the machine is low latency audio production. That puts me in a small minority at least as far as Linux users are concerned. It's just a bit of a whinge of mine that Linux has such potential in the audio area and so many wonderful things have been implemented but it seems sometimes that there are too many almost-but-not-quite-compatible sound systems, all of which do useful things, and it would just be so great if they'd all co-operate... but I'm very aware that is the nature of the beast... I'm a utopian.... In a perfect world everything would just work.. :)

Intreresting. One day maybe, when time allows.. :)
