I thought so, but I can't seem to find where to turn that off! I am running windows XP with a C-Media sound card. Any suggestions?Not good. There's a problem.
It may be that you have a 'monitor' mode turned on in the soundcard. This results in the line-in being enabled in playback (checkable in the windows playback mixer).
Examine the soundcard application software and see if a monitor is enabled.
Yes, just a loopback measurement of the SC. It is a desktop. It could be a soundcard. I could use another computer if I need to or buy a new SC. What is a good inexpensive SC to buy?Still looks like there's some interference or distortion there. The midrange dip is strange. If this is a lap-top try turning your wifi off and make sure you are running off of the battery pack and not the wall. Also check your levels to insure that something is not overloaded. May possibly be the sampling rate used? I had a problem like this when I first started, but I can't remember exactly how I corrected it:scratchhead:
This is just a loopback measurement of the SC right?
