sound card detected, but no sound...

I wrote about this last week...Suddenly my sound just stopped about two 
weeks ago.
No errors or anything, it just got all garbledy while listening to a song
on a profile (like myspace, only in Spanish), so I turned the
speakers off, and, the next time I tried to listen to anything on the 
machine, like
the next sound.
I thought maybe something fried the on-board audio controller, so, I 
a new sound card, which arrived today.
I installed it, and, apparently it is detected, but, I still have no sound.
Please advise.

I did lspci, and it gives me both, the on-board sound, and the new card,
I just bought:

0000:00:14.2 Audio device: ATI Technologies Inc SB450 HDA Audio (rev 01)
(that's the on-board audio device, and)

0000:02:03.0 Multimedia audio controller: C-Media Electronics Inc CM8738 
(rev 10)
(this is the new card I just acquired).

I get no errors from any audio software.
Heck, mplayer, xmms, rhythmbox, kaffeine, etc., all appear to happily 
play music, and
I can sit here and watch the pretty visual effects 'til my eyes bleed...
in complete silence.

The speakers are on.  Kmix actually allows me to choose which of the 
sound cards,
and I can choose either and turn all the volumes up to ear-splitting 
levels, and still
no sound.
No test sound from the KControl>sound & media> sound system> play test 
sound thingy.

I can switch the speakers for another pair, plug in headphones, or run 
the sound out to
my stereo system, and still, you guessed it...the sounds of silence.
And Simon & Garfunkel aren't playing here.

lshw gives me:

Of course, I haven't the slightest idea what any of the output from 
either of those commands
signifies, in the grand scheme of things.

Likewise, I did
$ sudo modprobe snd-cs4236;modprobe snd-pcm-oss;modprobe 
snd-mixer-oss;modprobe snd-seq-oss

and got:

FATAL: Error inserting snd_cs4236

Which might as well be Swahili, and since I only speak English, French, 
Spanish and Portuguese,
it doesn't help me...
I also did
$ aplay -l

and got:

Something tells me that the modprobe output is most significant 
(something about FATAL!! FATAL!!
makes me think that there might be a problem there...I don't know...)

In any case...I've got a sound fact, two, installed, and the 
machine doesn't seem
to have any trouble finding them, and apparently even believes that it
can successfully play sound, from all the behavior I see, but, no sound 
comes out.
This tickety-tackety of the keyboard is getting to sound lonely, and 
Comcast doesn't
have a MPB (Musica Popular Brasileira) channel...
No Legião Urbana, even.
And the Latino Rock station doesn't play enough Maná.

Oh yes, and this is on Dapper Kubuntu.
Or, at least Dapper with KDE, since I installed with the Ubuntu disk and 
Kubuntu-Desktop afterwards.
Any ideas?
Any and all assistance appreciated, as always. (a*7)
