You get echo, but this is ok. You probably have "Mic volume" not set to 0 and echo comes from record loopback (this is where delay comes from). When you set "Mic volume" to 0 you will hear delayed mic signal, but without echo. ---------------------------------------------------------------------- pzad - 08-06-2004 15:03 CEST ---------------------------------------------------------------------- Helped this ??? ---------------------------------------------------------------------- quinn - 08-06-2004 15:15 CEST ---------------------------------------------------------------------- I'm sorry, I missed the first reply. No, that didn't help. I have microphone output completely muted as well. (And am using headphones, so no analog feedback is present.) ---------------------------------------------------------------------- pzad - 08-30-2004 12:14 CEST ---------------------------------------------------------------------- I missed your reply :-) I will try this again. Test if you have Mic Volume to 0. If echo is still there, try to set AnalogMix volume to 0. Helped this ???
