Hi

I cannot make my edirol ua-1a sound under 2.6.15. I have patched with
the rt-21 patch, which otherwise work fine, but the problem is the same
with an unpatched 2.6.15. And the problem is the same under
debian/stable and debian/unstable. Same with multimedia-kernel from
demudi. I was starting to suspect that is was dead, since everything
looked fine, apps (audacity, aplay, csound) ran happily, nothing in
dmesg. But as a last desperate atempt I booted in a plain debian/stable
install with debian kernel 2.6.8, and it just worked.

To test I run: aplay -D hw:1 test.wav

And I have:
[atte@email-addr-hidden atte]$ cat /proc/asound/cards
0 [SI7012 ]: ICH - SiS SI7012
                      SiS SI7012 with ALC200,200P at 0xdc00, irq 10

So now (before I post my kernel .config and all) I'm wondering, could it
be a simple something that needs to be flipped somewhere? Where to look
for additional information?

I tried installing udev, but that didn't change anything...
