Summary: Echo with SB Audigy and microphone input
Description:
When in "loopback" recording mode, where the recorded audio from the
microphone is played back (Easiest example would be the Recorder plugin
for XMMS), even when every other capture channel is at zero volume and the
sound is output through headphones, microphone input still echos

I tested this. 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.

Helped this ???

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.)

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 ???

Yes, I am completely and utterly sure that microphone output is set to
zero. Zeroing out either Analog Mix playback or recording does not help
either.
