Also, try sound-2.6.git tree instead. git://git.kernel.org/pub/scm/linux/kernel/people/tiwai/sound-2.6.git
patch_realtek.c are identical and hda_intel.c show only minor differences which don't look related in this and "alsa-kernel" get tree that I used. Do you think I should still try it?
You should keep tracking the sound git tree if you'd like to catch up the upstream changes quickly. Right now there is no big difference regarding Realtek stuff, though.
Is there some "official" method of debugging this: is it possible to see what the driver is doing with the data stream fed to it (other than inserting a bunch of printk's in the code)?
You can use hda-verb program to access the codec verbs directly. Also you can use the hda-emulator for debugging. But you have the real hardware, so it's maybe better to use your own hardware.
The programs can be found in ftp://ftp.kernel.org/pub/linux/kernel/people/tiwai/misc/
