Just wondering if anyone has found time to look into fixing the input quality of the usb quattro?

I'm not sure it has ever functioned perfectly for input quality.

Currently I get a better sound quality from my $10 cmipci than my $400

usb-quattro ;-P

There is a constant crackle in the audio stream.


there is a thread on this on the alsa bugtracking system ... there is a
patch available, but it's not fully working for me...
using kernel 2.6.6rc2 with the patch to the usb subsystem to allow the
using of the quattro, i'll only have to restart alsa about once or
twice. (probably i still had problems with the alsa patch because of
kernel 2.6.6)



Thanks for the tip.

Just to confirm what I read in mantis. The quattro can only record in big endian mode and playback in little endian?

How does this affect jackd?

AFAIK it's not possible to have dual modes while using jack...



kernel 2.6.6rc2 is very broken with respect to USB. Use 2.6.6rc3 or above.
