Well, I actually tried to google for an answer, and found a few replies, but none of them worked for me.
You’re on headphones, check.
Do you like recording on-line content like YouTube sound? The settings to do that, can do this.
I have an audio track (recorded somewhere else) which is a drum track. “Track 1”.
Now I open a new track “Track 2”, where I record the guitar. I need to hear the drums, obviously, to play on time. I can hear the drums fine, and the microphone does record the guitar as played in front of the microphone. But somehow when, next, I listen to Track 2 (muting Track 1), I not only hear the guitar but also the drums.
This happens even when during recording I unplug the headphones and switch off the microphone (for testing): the sound of the drums still end up on “Track 2”. So, somehow, somewhere track-1 “leaks” into track-2.

I don’t record YouTube videos. I found on the net some replies refering to “Stereo Mix” or “What-U-Hear”, which - supposedly - are settings on Windows, right? The problem is, I cannot find in any settings (Sound, Microphone, etc…) on my Windows these settings at all. Which makes me think my PC (or soundcard) somewhere hidden has these options set without giving me the chance to switch them off.
This morning, I tried something else: I copied my entire “.au” project to a different computer (Windows Vista, laptop), and got the same Audacity version installed there. Here, it doesn’t happen. As a matter of fact, here I cannot find this “Stereo Mix” or “What-U-Hear” option either, but in any case, it seems I don’t need to, it works fine here.
So my conclusion is that somehow this “leaking” depends on either the OS (Windows XP) or on the soundcard (RealTek on XP, Microsoft High Def. Audio on Vista). For the moment I continue on Vista, although it would be easier for me to work on XP because it has more memory.
Am I close?
I think you are right about the “SoundMix” and “What You Hear” options, but unfortunately I cannot test this because I cannot find this on my computer. (Which by the way, is installed in the Spanish language, but anyway, I haven’t seen anything that could be rougly translated to those words).
Anyway, thanks for your advice, I think you are right, even though it doesn’t solve my problems your help is very much appreciated.
