You actually *do* have S/PDIF. It says so in your alsa-info.sh output. I double-checked. We can't make a permanent change unless we know this works too. One of your line-out or headphone jacks doubles as S/PDIF. On my laptop, there's a headphone symbol with "S/PDIF" written under it. If you or someone you know has a digital receiver, you can test it that way.

Also, did you test your microphone?
