Anyone know how the audio signal inputs and outputs are typically handled as far
as how the signals are routed and mixed?
It seems that the audio signals that are internally generated in the PC are mixed in
with the line input signals. In other words, anything that I send to the line output jack
is automatically sent to the line input circuitry.
I need to remove this line out signal from being mixed with the line in signal. I found
something called a mixer in the sound settings but turning it off killed the output signal
completely. Is there some standard setting that I should be looking for?
I would expect to find such settings in something like an input mixer or record mixer,
but I can't find any such thing.
The audio is on an Intel motherboard and is running XP. I've seen the same problem
on an HP laptap.
