Hi again Benny, An interesting anecdote raised by a colleague that any sound heard on the computer is passed to the WM even it is not a talk on the microphone but say music playing. This might be causing the echo since this creates an endless loop of voice (PC-Mic -> WM-Speakers -> WM Microphone -> PC-Speaker -> PC-Mic -> ???) - In fact, when muting the WM device the sound is crystal clear. I know that in audio program there is a distinction between the line-in and the microphone (there is also third mode stereo-mix) - so if one wants to record audio on the computer it can be done against either one of the channels. We were wondering then, whether it is possible to apply the same on the Desktop software so only microphone sound would be sent to the other endpoint. As a plan B I might be giving up the whole wince environment for this moment in case people on the mailing list will report that far better results were gained on Symbian. Will be back in the lab tomorrow to keep checking on the issue. Eventually I would like to thank you again for sharing with us your software and knowledge, time and energy. Best regards, Tzury
