wine users - Sep 2009 - Soundcard detection failing

Hello all!  I'm as new to these forums as I am to Linux, so please bear with
me if I fail some of the etiquette!

I'm running an Ubuntu 9.04 distribution.  Sound has so far worked
wonderfully in Ubuntu proper (playing music in Movie Player [current default]
and through Firefox [Pandora] causes two streams to play; I don't seem to
have issues with mixing!)

PROBLEM:

Ventrilo under Wine doesn't allow me to use my microphone (though I can hear
others just fine).  In the course of troubleshooting this, I've found that
the Audio tab under winecfg does not list the appropriate devices. 
Specifically, it looks like:

- Sound Drivers
   - [Check] Alsa Driver
      - Wave Out Devices
         - default
         - default
      - Wave In Devices
         - default
...

No other drivers (OSS, JACK, NAS, EsounD) are checked.

HARDWARE:

I've run across several threads recommending to use the command
/proc/asound/cards to determine which sound cards are on my system.  This
command does not execute ("command not found"; and then only in sudo).

"aplay -l", however, returns:

**** List of PLAYBACK Hardware Devices ****
card 0: Intel [HDA Intel], device 0: STAC92xx Analog [STAC92xx Analog]
  Subdevices: 0/1
  Subdevice #0: subdevice #0
card 0: Intel [HDA Intel], device 1: STAC92xx Digital [STAC92xx Digital]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 1: default [Microsoft LifeChat LX-3000 ], device 0: USB Audio [USB Audio]
  Subdevices: 1/1
  Subdevice #0: subdevice #0

So Ubuntu recognizes my vendor soundcard and my USB headset.  Why doesn't
Wine?

N.B. I cannot edit .asoundrc as some threads I've found suggest; I do not
have it on my computer at all.  I've tried creating it and putting in the
helpful code to no avail.

SOFTWARE:

In the Volume Control panel, I have selected "HDA Intel (Alsa Mixer)"
as my Device.  I've "enabled" everything under the preferences tab
and ensured nothing is unnecessarily muted.

In the Devices tab of the Sound Preferences, Autodetect is enabled for Sound
Events playback, Music and Movies playback and Audio Conferencing playback.  For
Audio Conferencing capture, I have "Microsoft LifeChat LX-3000 USB Audio
(ALSA)" selected.  The test for each of these sections passes.  The Default
Mixer Tracks device is "HDA Intel (Alsa Mixer)" with
"Master" highlighted in the box below.

DONE SO FAR:

I don't rightly know all that I've done up to this point but I reversed
most of it after it failed.  I have downloaded and installed some packages
(alsa-oss, libasound2, lib64asound2 (though I don't think I have a 64 bit
system), libasound2-dev, lib64asound2-dev, libasound2-plugins).

I greatly appreciate any help!

Also, I haven't been able to hear sound/music in World of Warcraft, though I
have not specifically sought to address this issue.  The various sound effects
(joining a server, changing channels) work in Ventrilo.  The cause of this may
be the same as the cause above.

Sweet, I'll definitely check into that.  I think the issue has to do with
software and sound input rather than output, but I haven't looked into what
you suggested.  Hopefully I'll learn something if nothing else!

Thanks for the response!
