Got sound from the Intel device on the system board.  Oddly enough 
there was a plastic cover over the sockets on the chassis back.  Pried 
it off to plug the speaker jack.

Here is some further info.

Read https://wiki.debian.org/ALSA and followed the Troubleshooting and 
Checklist sections.

root@joule:~# cat /proc/asound/cards
 0 [ICH5           ]: ICH4 - Intel ICH5
                      Intel ICH5 with AD1980 at irq 17
 1 [Live           ]: EMU10K1X - Dell Sound Blaster Live!
                      Dell Sound Blaster Live! at 0xdf20 irq 22
 2 [U0x46d0x807    ]: USB-Audio - USB Device 0x46d:0x807
                      USB Device 0x46d:0x807 at usb-0000:03:08.2-3, high speed
 3 [Set            ]: USB-Audio - C-Media USB Headphone Set
                      C-Media USB Headphone Set at usb-0000:00:1d.0-2, full speed

Mostly consistent with visible hardware.  Really just one USB.
Odd that the Intel device refers to both ICH4 & ICH5.

root@joule:~# alsactl init
Found hardware: "ICH4" "Analog Devices AD1980" "AC97a:41445370" "0x1028" "0x0155"

Initialize one device?  According to the manual, all should be initialized.

peter@joule:/home/peter$ aplay /usr/share/sounds/alsa/Noise.wav
Playing WAVE '/usr/share/sounds/alsa/Noise.wav' : Signed 16 bit Little Endian, Rate 48000 Hz, Mono

That gives the white noise from ICH(4|5).

Try initializing other devices.

peter@joule:/home/peter$ alsactl init Live
Found hardware: "EMU10K1X" "SigmaTel STAC9708,11" "AC97a:83847608" "0x1102" "0x1003"

peter@joule:/home/peter$ alsactl init Set
Found hardware: "USB-Audio" "USB Mixer" "USB0d8c:000c" "" ""

peter@joule:/home/peter$

They appear to initialize.

peter@joule:/home/peter$ aplay -D Live /usr/share/sounds/alsa/Noise.wav

Initialized but no sound. ?

Further ideas and tips?

Thx,             ... P.
