7.1 analog inputs/outputs are missing for unknown reason (we need a log, 
see below, to see why). And second spdif is indeed not supported at all 
out of the box on any card, that's a known bug. Other than that, the 
list of profiles looks sensible.

MIDI is completely outside PulseAudio territory.

So it looks like ogg123 successfully plays its stream through a wrong 
card. Please try to use pavucontrol to fix the situation: either set the 
new card as fallback on the third tab, or use the first tab to move the 
ogg123's stream while it is playing.

Please run the following command (one line, with ";" in the middle, 
that's important for timing) from a terminal:

killall pulseaudio ; pulseaudio -vvv | tee pulse.log

If it says "already running", just try again, you have to win the race 
vs autorespawn.

While that extra-verbose copy of PulseAudio is running, set the new card 
as a fallback device in pavucontrol and repeat the ogg123 test. Move the 
stream if necessary. Adjust the volume using pavucontrol just to see if 
this operation works correctly.

Then, when it finishes playing, "killall pulseaudio", and then we will 
get a complete "pulse.log" file. Place that somewhere in a pastebin for 
our examination (it will be too large to attach).

Then, you can run the alsa-info.sh script from here:


It will gather some information from your card and paste it to a pastebin.

Once I see all of that, I will ask more questions about the card.
