thanks a lot for taking care for that issue.
I just tried it out by modifying the following files from the 2.6.26-rc3 kernel:
sound/pci/Kconfig (modified by hand)
sound/pci/ice1712/ice1712.h (modified by hand)
sound/pci/ice1712/envy24ht.h (modified by hand)
sound/pci/ice1712/ice1724.c (copied from the actual Git snapshot)
I double-checked all the handmade changes, should be ok.
Midi in via "amidi -p hw:0 -d" works now without problem,
but when trying to write to the device, for example by "amidi -p hw:0 -s txdata.syx"
it causes an immediate crash.
That would not be a problem for me, but jackd probes all ports, and is unusable now.
Perhaps i forgot a patch, is the output working for you?
