Hi,
I made a few more tests, with a other usb sound card (behringer UCA202), and
I did not have any problem with rosegarden. But I still have some issues
with Pure data :(
I also tried the last patch from Adam Sampson, on my 2.6.26.3-rt3 kernel but
without any success.
I think, but I am not sure that this is an alsa-driver issue (usb-caiaq
module)
Perhaps we could directly contact the main developper of this module :
Daniel Mack daniel at caiaq.org
Cheers,
Mysth-R
