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?

Please note that mpu401 is for midi keyboard and synth through midi cable ,
if you just want to play midi file, install software synth (e.g.
timidity).

aplaymidi -l

 Port Client name Port name
 62:0 Midi Through Midi Through Port-0

It seem that you are using ALSA-1.0.10 or eailer version which is
different from your reported version 1.0.11

http://hg-mirror.alsa-project.org/alsa-kernel?cmd=changeset;node=ad7a63c4db69;style=gitweb

The source code of snd-via686a (alsa-0.9) seem not available on CVS
anymore after merge into via82xx.c

but what i want is to record/play music with a external midi keyboard.
I report i was using a 1.0.11 version of alsa because that was the output
of `amidi -V`.

The alsa drivers are those included with debian kernel 2.6.15-1-686. I'm
not sure about how to ask the system to tell the drivers version.
