Into.the.Void.

big title huh?

I had tried various applications for VoIP in Linux, Gnomemeeting, kphone, skype, etc etc and I was always told that the remote party heard an echo of his/her voice. My side was perfect…but the opposite side was unacceptable.
The solution to the echo problem was to tweak audigy2 capture values in alsamixer or alsamixergui.

Fire up alsamixer…you should probably see that the “View: ” title on top says “Playback”. Go to microphone and set it down to 0..that’s right..zero. Then press tab once and the “View: ” title will switch to “Capture”. Set PCM capture to 0 (zero) and mic value around 80-90.
The mic boost (+20db) is usefull to me too…use it if you want.
In alsamixergui: set the first PCM slider as high as you want and the second one to zero. Then go to mic and set the first to zero and the second one to 80-90.

After that the remote parties I talked to stopped bugging me about echo problems. So I think that’s the solution.
