[linux-audio-user] Problem with MPU-401 MIDI

[Vincent Jaubert]

Hello, i'm trying to make my midi keyboard work on my ubuntu edgy box.
The keyboard is connected by midi through the Game/Midi port of my ASUS
P4P800 Motherboard (Intel audio chipset).

amidi -l gives me this

Device    Name
hw:1,0    MPU-401 UART MIDI
hw:2,0    Audigy MPU-401 (UART)
hw:2,1    Audigy MPU-401 #2
hw:2,2    Emu10k1 Synth MIDI (16 subdevices)
hw:2,3    Emu10k1 Synth MIDI (16 subdevices)


The Game/Midi port is the hw:1,0 MPU-401 UART MIDI.
But when i do a cat /dev/snd/midiC1D0 (which does exist), i get an I/O
error.

When i do a lsmod | grep snd
i get this

Since the keyboard works under winxp, i think it's more a driver than a
hardware problem.

Has anybody any idea that could help me ?
Thank you in advance.
