I'm quite surprised (but > not doubting you) if that's the real reason your UA-20 doesn't work. I got the vxpocket and have been experimenting. You (and others) are right. The issue isn't with the sample rate. I was getting the same errors with the vxpocket and jack as with UA-20. "The audio interface "hw:1" doesn't support any of the hardware sample formats that JACK's alsa-driver can use." The problem seems to be that when compiling jack the alsa-driver looks to see if the system is big or little endian. It selects the sample formats based on that. Problem is the powerbook is big endian and the vxpocket uses little endian. digger
