Are you using cvs or 0.9rc3? Can you send the output of qinit? BTW I
didn't write it. Takashi whipped it up for me while we were testing and
it has become part of my startup scripts so I thought it would be useful
for other users too.
Apart from that the quattro has no mixer elems. The only way you can
adjust the volume is using the output level buttons on the box or using
software mixing like in ardour, alsaplayer, xmms (equilisation). You
should be using an analog mixer with it if you want to record at
