Okay Patrick... more headaches for you maybe? I finally bought a Quattro. All seems fine except I can't read/write to it. I assume it has something to do with this 'initialization' problem Takashi has mentioned, but I'm not sure. I'm really hoping to get this working soon so I can include it in the next Mandrake Audio HowTo blah blah. I used Patrick's .asoundrc, and the module loads fine. Everything that one expects shows up in /proc/asound.
