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?

What does that have to do with the driver failing to detect the MPU port?

May be via82c686b cannot use PCI BAR2 as mpu port when it BAR2 is > 0x1000
