<snip unhelpful part>
Below is the part that lists devices that output sounds. It's only
showing one device, so theoretically the USB device isn't confusing
PulseAudio.

With some devices you can switch the headphone jack/speakers using
`pacmd set-sink-port 0 <port>`, where <port> is one of the ports
listed below. Unfortunately, it doesn't look like you can do that
with your card. :-(
I suppose there's a small chance that the amplifier business is
causing problems, so it ` pacmd set-sink-port 0
'analog-output;output-amplifier-off' ` might be worth a shot, but try
the set-card-profile thing explained below first.

And we're finally to the actual hardware:

In my experience, having the active profile set as anything with
"input" in it results in no sound, though I haven't the slightest idea
why.
Try `pacmd set-card-profile 0 output:analog-stereo`.

Below would list all the apps feeding or eating sound from PulseAudio
at the time you ran the command, if there were any. If you play some
sound, you can see the application playing it listed here and what
audio device it's using. Might be useful if you attempt to use the
USB card again.

Sorry I can't be of more help. If any of the above doesn't work,
you're probably right about it being a hardware issue. Everything
else in PA-land looks fine.
