Try to load it with modprobe snd-mpu401 pnp=0 port=0x330 irq=5 The port address us almost always 330; when not, there will be error messages in the system log when you try to send something. The interrupt number may be wrong (i.e., MIDI input will not work), so you should try several values (5 and 10 are the most likely). What mainboard are you using? HTH Clemens
