Takashi,

I finally got the hardware set up again to test the patch. I noticed
that it was already applied to hg, so I just used the latest hg code
to test. With the new code the 2nd device was always failing with an
-EBUSY error. I poked around adding some printk's and noticed that the
device count wasn't being incremented for subsequent cards. I fixed it
and submitted the patch. With that modification it appears to be
working now:

$ modprobe snd_hda_intel
ACPI: PCI Interrupt 0000:00:14.2[A] -> GSI 16 (level, low) -> IRQ 16
hda_codec: Unknown model for ALC883, trying auto-probe from BIOS...
ACPI: PCI Interrupt 0000:01:05.2[B] -> GSI 19 (level, low) -> IRQ 18

$ aplay -l
