Hi!
I don't know the solution yet, but I have news.
I've boot my old system and it still works perfectly with the Edirol
usb card. I tested the sound with the old kernels, and with the new
kernels also. And it works.
So now I'm copying every configuration file I can think of, every log,
every relevant program's output I can imagine... to compare to those
in my new system. Hoping I'll find something.
several places I've looked into:
ps -aexw
lsmod
cp -r /proc/bus/usb/*
cp -r /proc/asound/*
find /etc/ | grep alsa
dpkg -l
~/.asoundrc
/var/log/messages
/var/log/kern.log
/var/log/debug
/var/log/dmesg
If you know more places where I should look I'd be very pleased to
hear it. And when I find the solution to the problem, I'll try to
write it in the alsa-project wiki, ua-25 page.
regards
joseLuis
