hi list just did some testing yesterday with pd and the m-audio quattro, it seems that the device is finely working with a standart unpatched kernel 2.6.7 and the latest alsa-cvs release where the little/big endian issue is already included. try to see if it works with jack now. have some problems to configure qtjackctl from source. why does it not find my qt variables?? checking whether QTDIR environment variable is set... no configure: error: QTDIR must be properly set. any ideas what i have to do? best M
