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.

Initialized but no sound. ?
Further ideas and tips?
Thx, ... P.
