OK.

Then it must be something in the driver communication.
Miles, do you have proper /dev/snd/* entries?

Hello,

I have no /dev/snd directory.
/dev/sndstat contains:

Sound Driver:3.8.1a-980706 (ALSA v1.0.12rc1 emulation code)
Kernel: Linux Dumbleedor 2.6.18-rc4-mm3 #2 Tue Aug 29 01:26:36 PDT 2006 i686
Config options: 0

Installed drivers:
Type 10: ALSA emulation

Card config:
Intel 82801DB-ICH4 with unknown codec at 0xe0100c00, irq 17

Audio devices:
0: Intel 82801DB-ICH4 (DUPLEX)

Synth devices: NOT ENABLED IN CONFIG

Midi devices: NOT ENABLED IN CONFIG

Timers:
7: system timer

Mixers:
0: Conexant id 30

Also, "cat /proc/asound/pcm" gives:

00-04: Intel ICH - IEC958 : Intel 82801DB-ICH4 - IEC958 : playback 1
00-03: Intel ICH - ADC2 : Intel 82801DB-ICH4 - ADC2 : capture 1
00-02: Intel ICH - MIC2 ADC : Intel 82801DB-ICH4 - MIC2 ADC : capture 1
00-01: Intel ICH - MIC ADC : Intel 82801DB-ICH4 - MIC ADC : capture 1
00-00: Intel ICH : Intel 82801DB-ICH4 : playback 1 : capture 1
