asterisk users - Jun 2004 - MOH From Line In on a sound card

I know this issue has been discussed before and I believe that I once
saw a patch and someone on IRC told me that someone made a patch as well
but I am unable to find it.

I'd like to bring in the MOH from the line in on my sound card.

Does anyone have a patch for this? Otherwise, I'd definitely put up a
bounty for this because it's something I really want.  I want to use my
XM for MOH.

Thanks
