hello !
I just got a new (usb) sound card (ni audio2dj) and in order to easily
use it on my linux machine (ibm thinkpad t40), I had to try it with
pure:dyne carrot&coriander (usb boot).
But I am facing some issues:
if I use the usb soundcard (qjackd settings are default, just using alsa
driver), all my sc patches use double cpu than with my FW soundcard
(on my osx machine, the same patches use the same cpu with both my FW
and USB soundcards).
also, if I use my FW soundcard with qjackd (freebob and default
settings), it complains that ieee1394 and raw1394 are not loaded (no
errors but lots of xruns if I run qjackd as root ?!?). it works fine
with the same settings and same FW soundcard on miso soup.
so my questions are:
- are the cpu problem with the usb soundcard be related to bad audio
settings or does it look like a hardware issue (I'm running a thinkpad t40)
- how come qjackd doesn't run fine on c&c with freebob by default ?
(that was one of the reasons why I chose pure:dyne some time ago, I
couldn't run RT audio with "basic" distros, I always had issues, miso
soup saved my (linux) audio life =)
thanks !

ps: I had to try the usb card with c&c because the latest rt-kernel have
native support for the driver (usb-caiaq). If there is an (easy) way to
get this driver running on miso soup, I'm all open ;)
