Again, perhaps I'm oversimplifying... but if you plugin speakers then your microphone is probably able to pickup their output, or a reflection of it, and transmit it back.

Yes. For $10-$30.00 you can probably find a headset that does standard usb sound and would work easily and reliably. I've used "Logitech ClearChat Comfort USB" (http://www.google.com/products/catalog?cid=3844041679359977382 ) for a few years with skype and for other purposes and it's been solid. The volume control on the cord controls the headset volume directly through kmix, putting up a nice volume-bar just like you'd see in Windows (I use KDE desktop, kmix provides the volume control widget on the taskbar). And it has a microphone cutoff switch on the same control, with a red led that flashes when it's muted. I assume you want to get google talk running? After plugging in such a Headset and logging in to the desktop, follow my instructions about "wrappering" GoogleTalkPlugin as a script that sets special ALSA environment vars then calls GoogleTalkPlugin-bin. This enables the headset to be accessed directly via the plugin's auxiliary program, leaving your standard "default" device available for browser/flash/java to use via dmix, pulseaudio, etc: http://permalink.gmane.org/gmane.linux.audio.users/67117 It is working very well, IMHO. There is some clicking and low-level noise audible on the landline receiving the call from google-voice, and the landline caller also noticed some echo of their own voice despite the low potential for sound bleed-through from the headphone to microphone. I've recorded this and did hear the clicking and noise, which doesn't emanate from the headset->USB->ALSA part, leaving me to think there might be some issues with GoogleTalkPlugin or the google network. Either that, or they've taken that the standard level of "switching noise" sometimes heard on long distance phone calls is acceptable call quality level for their system. Given the cost -- free -- and the fact that it gives me free calls throughout the continental US, I'm not complaining.... However if the call quality is so bad that you do want to complain, this may be the best place: http://www.google.com/support/forum/p/chat/label?lid=18819d87e4369fa5 -- Niels. http://nielsmayer.com ------------------------------------------------------------------------------ This SF.net Dev2Dev email is sponsored by: Show off your parallel programming skills.
