Hi Raul: If you've run the snddevices script you also need to load the drivers with the modprobe snd-card-your_synth. If you get the same error from amixer then try to save an asound.conf with the alsactl store command. You shouldn't need to do that but often I found if I've changed sound cards or something I need to save a file before amixer can read the headers.
