[linux-audio-user] Getting USB Audio Quattro to work

Hello! Somebody told me a few of you have managed to get M-Audio's USB Audio Quattro to work. I'd like to join your ranks, but I'm having a small problem. By the looks of things the USB settings are all correct and the ALSA (0.9.3) kernel module loads like it should, but the alsasound script gives me a peculiar message: Starting sound driver: snd-usb-audio done No state is present for card tm It then automatically writes a new asound.state file containing only this: state.tm{ } I don't know if this is good or bad or unimportant, but nonetheless, I don't hear anything when playing back sounds. I found the .asoundrc file for the Quattro by Patrick Shirkey somewhere and I saved it to my own .asoundrc. Here is what some of the aplay commands output: This actually _looks_ good, but I can't hear sound: denis@denlap denis $ aplay /usr/kde/3.1/share/sounds/pop.wav Playing WAVE '/usr/kde/3.1/share/sounds/pop.wav' : Signed 16 bit Little Endian, Rate 44100 Hz, Mono Here I tried to use the device names from the asoundrc file, but then I get an error: denis@denlap denis $ aplay -D quattro1 /usr/kde/3.1/share/sounds/pop.wav Playing WAVE '/usr/kde/3.1/share/sounds/pop.wav' : Signed 16 bit Little Endian, Rate 44100 Hz, Mono aplay: set_params:810: Channels count non available So, my question is, what am I doing wrong? Did I take all the necessary steps? Is there a way do get more diagnostics? I hope you can answer my questions, because this thing is pretty expensive for a paperweight ;-) Regards, Denis p.s. if you need more info, let me know. Just to be on the safe side, here's a few of my files. Note that the device is named 'tm' which is (i think) because of the (tm) in the descriptor. I really don't know how all of this wors though, so educate me please.
