I just bought a new machine and put Intrepid on it (32-bit), but have no
sound. It's a quad-core Xeon, with a Super Micro X7DA8 board, and I
took a SoundBlaster Audigy SB1394 from my previous machine and put it in
the new one. I disabled the onboard AC 97 audio via jumper (verified by
running "asoundconf list" both ways). Volume is normal, nothing is
muted, etc.

I had a chat with Mr. Google and ended up taking this advice:

http://ubuntuforums.org/showthread.php?t=866965

but it didn't help. All the diagnostics show that the sound card is
there (lshw, lspci, etc.) and the PulseAudio Manager looks normal (the
volume meters move when I play a file), but there's no output. I tested
with headphones plugged directly into the card. I know the card is
still good because I swapped it back into the previous machine, plugged
headphones into it, and played a .wav file.

I'm confused because all the diagnostics seem to show that the card is
working properly, but I have no output. Suggestions?

First the caveats. I'm currently finishing off the download of Kubuntu 8.10
(on dialup), having already dl'd Ubuntu 8.10, but neither are installed yet.
I don't use Pulseaudio, and have it disabled in Fedora8, 9, and Kubuntu HH
8.04. I use KDE, and am a bit clueless about Gnome.

Ouch.

Can you post the output of, cat /proc/asound/cards . Your Audigy card should
be card0. Sometimes problematic drivers can insist on grabbing card0. The
same goes, if you have any audio related devices plugged into the USB, a
webcam, usb midi keyboard, etc, and snd-usb-audio has grabbed card0, and your
Audigy card has been relegated to card1.

With the onboard sound disabled, I get:

0 [Audigy ]: Audigy - Audigy 1 [Unknown]

You could post the output of, lsmod | grep snd , just to see which modules
are loaded.

Also have a look in /etc/group. Your user name should be in the audio group,
and if it exists, the pulse group.

audio:x:29:pulse,cenbe,shadowm
pulse:x:115:shadowm
pulse-access:x:116:shadowm
pulse-rt:x:117:shadowm

Which app are you using to play sounds? There is usually in it's audio
settings an option to use alsa directly, or other options. As you say though
that the Pulse Audio Manager indicates that the file is playing, perhaps that
bit is ok.

aplay <filename>
aplay -Dhw:0 <filename>
play <filename>

What does alsamixer show, when you open it as user in a terminal. I know on
Fedora 9, it only showed one slider before I disabled Pulseaudio, and after
that, several sliders for my hda intel card.

Shows only Master (Pulseaudio).

If I do alsamixer -Dhw:0 I get all the controls for the Audigy.

If I kill pulseaudio with "pulseaudio -k", then "alsamixer" shows the
Audigy controls, but still no sound.
