Trying to mute "line-in" on Audiophile 2496 to eliminate inputmonitoring echo.

[Doc]

Trying to do input monitoring of effects, in this case reverb in Home
Studio 2. I'm using Aux 1 to add some reverb to the headphone mix
without affecting the recorded track.

Looking in the help files, it mentions the issue of "echo" when doing
input monitoring that I assume is the chorus-like artifact I'm hearing
in the headphones. As I understand it, what I'm hearing is the delay
between the direct line output and the effect as routed through CW. Is
that correct? This only happens when using the effect, I don't get any
echo when monitoring dry.

To eliminate this, they advise to mute the line-in for the soundcard.
However nothing on the mixer of the Audiophile 24/96 is labeled "line-
in" as such. To be honest, I'm still trying to wrangle with exactly
how the Monitor Mixer on the card works, it seems somewhat
counterintuitive. Nothing I've tried so far has worked.

Anyone have familiarity with using this card with CW and how to get
rid of the echo? Also, anyone know of a resource where the 2496
monitor mixer is explained better than it is by the M-Audio manual?

Thanks for all info.

When using a DAW with its own monitor routing, the Monitor section of
your soundcard is redundant. Confusion often occurs when people
think it OUGHT to be doing something, and try to make it :-)

Hmm. I'm not sure I'm following you. What other monitor routing would
there be besides that of the 2496? When I bring up the windows "Volume
Control" it references the 2496.

Yup. The 2496 performs a simple function, getting audio in and out of
the computer. I think it also has a monitor mixer that will loop an
input straight out again. But you're using a DAW that has its own
monitor routing (including monitoring an input through an effect).

I think you're using the card's monitor mixer AND the DAW's. The
slight delay on the DAW input monitoring isn't a problem. But it IS
slightly more delayed than a direct external loop-back, hence your
phasing effects.

Some people find the small delay of ANY digital monitoring
unacceptable. The sound takes a small but measurable time to be
digitised, switched and re-exported. These people are happier with
monitoring through an external analogue mixer. But I don't think
this is what you're talking about.

It´s pretty easy:
- your card´s "Line IN" is labeled "H/W IN 1/2" in the M-Audio Control panel
(=software "monitor" mixer)
- switch to "Patchbay / Router" tab and set "H/W Out 1/2" and "H/W Out
SPDIF" to "Monitor Mixer"

Make sure, you move up ALL "faders" in the "Monitor Mixer" tab - otherwise,
you won´t hear anything, when the HW OUT is set to monitor mixer!
Now you can control the volume of incoming signal (="line in") in the
output. It is only relevant for "direct monitoring" of the incoming signal,
so don´t get fooled by moving level indicators, even though the channels
are muted. The indicators show, how loud the incoming signal is.

BTW, I usually set all channel pairs to "Stereo Link", cause it´s easier
most of the time...

This should get you started and the rest can be found out by playing around.
