[GnomeMeeting-list] Quickcam 4000 pro + i810 7012 + ALSA problem

[Zoilo Gomez <zoilo xs4all nl>]

I recently purchased 2 Quickcam 4000 Pro's with built-in microphone 
(USB), and would like to use the built-in microphones.

I am using kernel 2.4.21 with gnomemeeting-1.0.2. Testing on 2 different 
PC's, one with built-in Via82xx audio chip, and another one with 
built-in i810 7012 audio chip. My sound-card is on sound-channel-0, the 
USB-mic is on sound-channel-1.

Video is working fine, but the MIC gives me a headache.

My first attempt was to use standard OSS. Things almost work, but there 
seems to be a sample rate difference problem, resulting in 'chipmonk' 
sound. However, I can use the Wizard + Audio test, although it results 
in distorted chipmonk sound.

Having consulted the mailing lists, I decided to try ALSA instead 
(alsa-1.0.5a), as ALSA seems to be able to adjust the sample rate. 
However, now I cannot pass beyond the Audio test in the wizard anymore: 
'Failed to open the device / Impossible to open the selected audio 
device (/dev/dsp1) for recording'. If I ignore this error and make a 
call, the error is: 'Could not open audio channel from the soundcard for 
audio transmission'.

All permissions are OK.

I can record from /dev/dsp1 using 'rec', and I can playback on /dev/dsp 
using 'play'.

Here is my /etc/modules.conf:
===========================
alias char-major-10-200 tun

What can possibly be wrong?
