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?

Hi again!

My message had a typo: the motherboard is not AOpen MX63LE, but AOpen
MX36LE.

I also tryed to load the module without parameters....

modprobe snd-mpu401

FATAL: Error inserting snd_mpu401
(/lib/modules/2.6.15-1-686/kernel/sound/drivers/mpu401/snd-mpu401.ko): No
such device
FATAL: Error running install command for snd_mpu401

... and a "MPU-401 device not found or device busy" is added to syslog

the outputs of the commands:

aplaymidi -l

What is the output of "cat /proc/ioports" and "lsmod"?
