i haven't got my hdsp working yet and i'd like to keep the quattro on an old laptop (kernel 2.4) for recording i'll check that ... thanks...

??? has the quattro/2.6 problem been fixed? i thought the usb subsystem rejects the quattro from not being compliant with the usb standard ... sure ... i've not been able to really use the alsa layer ... i always sticked to oss the only way for getting 4 channels out of pd ... i suppose with an old version of alsa (0.9.2 ???) i could get a 4 channel sound out of pd (0.36 ???), but i never tried jack that time ... arecord / aplay are probably working since they are the reference implementations of alsa ... but i'd like to use them with jack, not because of recording but live-sampling /-processing... cheers...

yes, i missed that!!! will these patches make their way into the main kernel or will i have to patch every kernel, i'd like to install manually? cheers...

For reference I successfully recorded for a few hours using 4 channels of the quattro over nfs and had perfect sound quality and no dropouts with arecord. One thing is that many people have reported getting very good results with jackd -d alsa -d -r 48000 -p 480 -n 3 -d quattro1/2 I think your seeing strange results in non realtime mode for other reasons. Do you use jackstart as a normal user? I always run my sound apps as root on this machine so haven't looked into non realtime mode.

hi juto, i don't think, it's a jack problem, but an alsa problem ... but since i'm about to use the quattro for recording only and i've got enough to do with solving my hdsp problems, it will probably take some time until i can test the recent alsa version ... but iirc 0.9.2 was the last version that worked fine with pd on my machine ... i don't know if it's related to that, but i suppose the problem with jack is the same as the problem with pd/alsa ... so, maybe downgrading alsa would solve the problem (until we found the changes between 0.9.2 and higher versions of the snd-usb-audio module... cheers... -- Tim mailto:TimBlechmann@gmx.de ICQ: 96771783 -- The only people for me are the mad ones, the ones who are mad to live, mad to talk, mad to be saved, desirous of everything at the same time, the ones who never yawn or say a commonplace thing, but burn, burn, burn, like fabulous yellow roman candles exploding like spiders across the stars and in the middle you see the blue centerlight pop and everybody goes "Awww!"
