No. forget about snd_seq_midi as I've an idea it's only for soundcards that have a hardware synth like my Audigy 2 Soundblaster. More important is the usbcore module which Ralf mentions is missing in your lsmod. It's a dependency for snd_usb_audio and I've had someone else in the past where that wasn't loading and caused similar problems to yours. So do a: sudo modprobe usbcore If it doesn't immediately resolve the problem add it on a line in /etc/modules and reboot as it may need to be loaded before snd_usb_audio as it's a dependency. You'll need it in /etc/modules anyway if there's something stopping it being loaded automatically. All the best.
