That makes two of us. I've reported similar problems a few weeks back. So the 
thread "snd-hda-intel, AD 1988b: SPDIF output not working correctly, volume 
low for analog output" maybe of interest to you too. (I posted a similar 
patch just a few minutes before your's by the way -g-)

Could you please tell me what board you have...? If you play back analog sound 
through spdif, do you hear "distortions" in the background like bass-like low 
frequency pumping and so on...?

Best regards,
Matthias Dahl
