Yep -- hardware midi, hooked up to the onboard MPU-401. Sounds really thin, 
but it's okay to play with.

Yes, dumb cut & paste error from when it was split off into its own 
function; please change the four "return err;" exits in (that version of) 
snd_galaxy_probe() with "goto error;"

It took quite long for you to look at /proc/interrupts and see which ones of 
four possible IRQs was unclaimed (the only thing autoprobing does)? Strange.

I don't see the mixer problem here, with the same card. Might it be a 
testing fluke caused by the unloading bug above?
