From Anssi Hannula:
"The CTLINDEX=x values in /usr/share/alsa/cards/HDA-Intel.conf are off when you have S/PDIF output in the same card as HDMI, which is often the case on Intel.
The workaround is to bump all the CTLINDEX=x values one step up in the HDA-Intel.pcm.hdmi.foo entries, i.e. CTLINDEX=0 => CTLINDEX=1 CTLINDEX=1 => CTLINDEX=2 etc, in the /usr/share/alsa/cards/HDA-Intel.conf."
Hmm.. my T420 does not have SPDIF and could possibly be broken by this change.
