BC, thanks for the help.
XP does not allow the microphone and loudspeakers both on at the same time. **
I need to have the OP explain what he wants to do.
Does he really want to hear his voice?There is a way to do it, but not documented.
** two reasons, Or three
1. The sound card is digital, not analog. Only inputs and pitputs are analog and there is not direct connection from input to output.
2. Once you r do that, (I have) you get a horrible squeal from the loudspeakers.
3. There is time delay,. Analog to digital, process, Then back to analog. Sounds like maybe 50 milliseconds.This will confuse most people, unless they have done do'ed something this that and have learned how to ignore time delay.
