Summary:                    snd-mpu401 don't load
Description: 
I have a Aopen MX63LE board with onboard sound managed by snd-via82xx
driver. It loads all necesary modules, includind snd-mpu401-uart, but no
snd-mpu401
The audio part of the driver works perfectly, but the midi port doesn't
work.

In BIOS i can set (and see) the mpu401 port (0x300 or 0x330) but there is
not a MPU401 IRQ setting in bios. When i tried to manually load snd-mpu401
(setting the port accordingly to BIOS) it doesnt work. I don't know the
mpu401 irq setting but i tryed them all. None of them worked. The driver
says "device not found".

Under windows xp the port works perfectly, so the hardware is ok. Anyway
under windows xp, i use a "system inspector" to monitor ioports and irq
usage, and i didnt see any irq assigned for mpu401 port, and the port
(0x330) wasn't occupied neither.

any idea?

Usually snd-mpu401 can be loaded without module options using ACPI PnP.
