RE: [GnomeMeeting-list] Bad echo only on Dell Latitude laptops

Christopher Warner wrote that I should turn off the playback of my mic
sound.  Here is my experience trying to do so:

When I use the audio test druid with a Panasonic laptop, I can use the mic
setting of the Volume Settings utility to control whether or not I hear
myself while I am talking into the mic.  However, regardless of the mic
setting, I don't get any echo in the GnomeMeeting playback.

When I use the audio test driud with a Dell Latitude laptop, I hear myself
while I am talking regardless of the mic setting in the Volume Settings
utility.  And I get echo in the GnomeMeeting playback regardless of the mic
setting.

The only other Volume Setting that appears to affect the microphone is
igain.  It acts as a general volume control for the microphone.

I have tested lots of different combinations of Volume Settings on the Dell,
and the only way I can control the echo is to just keep the settings low and
talk loudly.  The echo is then kept to a minimum.

Any further advice?

I've responded to this about twice I believe. The reason that the
panasonic laptops don't echo is because there is no playback via the
mic. IE. The mic doesn't take the feedback and play it through the
speakers. Your problem is simply that you don't want to and/or refuse to
turn off the playback of your mic sound. You should not hear your
voice.. The proper functionality is in number 3, that is also why the
Panasonic laptops work properly. Where you don't hear your voice
immediately. Again; turn off your playback volume for the mic.
