I had to guess on that one. The sb_init_diamond() function does not assign
mpu_config->irq and I don't have a printout of /proc/isapnp for this card,
so I guessed and asked for people to test it :-)

The mpu is no longer activated by default on cards with a mpu isapnp
device separate from the audio isapnp device. Reason being most people
don't use midi devices and so the IRQ taken up by them is wasted. To
configure the mpu device on such clones you must pass the module option
"mpu=1".  I've recently changed the name of that option to "uart401".

Thank you for testing and the correction! Could you please send me a copy
of your /proc/isapnp for this card? I'd like to add it to my growing
collection.

Thank you for your time,
Paul Laufer
