Uh?

Card 0 apparently cannot do SPDIF.

(iec958 is synonymous to SPDIF)

Look Ma, one SPDIF profile was found.

And another one was found.

And a third one was found.

Everything works perfectly. PA identified quite a few working
profiles. It will default to Analog Stereo. Now use a recent version of
pavucontrol to switch the card to an SPDIF device. Or use
"set-card-profile" on the pacmd prompt to switch. "list-cards" in
pacmd will show you the supported profiles of your cards.
