Any ALSA experts here?

Hey all,
I bought a USB webcam for a computer (running Ubuntu 8.10) that includes
an integrated microphone (The Microsoft NX-6000, they still make decent
hardware...)
In a reverse situation from most user problems, I have the webcam
working fine but not the microphone.
The response to `arecord -l` gives:
**** List of CAPTURE Hardware Devices ****
card 0: Intel [HDA Intel], device 0: AD198x Analog [AD198x Analog]
Subdevices: 2/2
Subdevice #0: subdevice #0
Subdevice #1: subdevice #1
card 1: NX6000 [Microsoft� LifeCam NX-6000], device 0: USB Audio [USB Audio]
Subdevices: 1/1
Subdevice #0: subdevice #0
I assume the Intel device relates to the conventional microphone jacks
on the computer.
If I try to run `arecord -D plughw:1,0 ./RecTest-1,0.wav`, I get:
Recording WAVE './RecTest-1,0.wav' : Unsigned 8 bit, Rate 8000 Hz, Mono
ALSA lib pcm_params.c:2135:(snd1_pcm_hw_refine_slave) Slave PCM not usable
arecord: set_params:932: Broken configuration for this PCM: no
configurations available
The output of `dmesg` related to the device appears to be
[ 11.815930] uvcvideo: Found UVC 1.00 device Microsoft<AE> LifeCam
NX-6000 (045e:00f8)

[ 11.852725] usbcore: registered new interface driver uvcvideo

Can anyone suggest what my next steps are?
Thanks!
