[linux-audio-user] usb soundcard not working in 2.6.15

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@aarhus atte]$ cat /proc/asound/cards 0 [SI7012 ]: ICH - SiS SI7012 SiS SI7012 with ALC200,200P at 0xdc00, irq 10 1 [UA1A ]: USB-Audio - EDIROL UA-1A Roland EDIROL UA-1A at usb-0000:00:03.2-1, full speed 2 [keyboard ]: USB-Audio - MK-249C USB MIDI keyboard Evolution Electronics Ltd.

Where to look for additional information? I tried installing udev, but that didn't change anything... -- peace, love & harmony Atte http://www.atte.dk
