That works a bit better: the module loads, and I can start jackd using the card. I suspect it's not passing audio correctly, because jdelay produced nonsensical-looking results, but I haven't investigated that any further yet. Stopping jackd provokes a similar-looking bug to before: partial backtrace (the top scrolled off my screen) at http://www.starlingaudio.co.uk/misc/201002191462.jpg Cheers, Colin. _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx http://lists.linuxaudio.org/listinfo/linux-audio-user
