Overdub on new track

I am having trouble trying to record tracks individually. I have a guitar pedal (USB) connected to Windows 7. The recording and playback devices on Audacity option shows the guitar pedal which I select. I first record the guitar rhythm on track one. Then add a new (stereo) track on which I record the lead guitar. When I playback the new track (with the lead) I can still hear the rhythm track (1) although that is muted. Is there a way of stopping the first track being recorded on track 2?
To troubleshoot the issue, I set the recording device on Audacity as the laptop mic and plugged in my guitar to the mic port. When I do the above exercise via the mic port, I get to hear both tracks independent of each other. What could be wrong?

Thanks

Ps. Please delete this post. I figured out the problem. If I set the playback device as the same the overdub happens. I set the playback device as the laptop speaker and now all tracks record individually.

No, that’s not normal, but sometimes it’s a chore to sort where it’s coming from.

Do you like to record internet music or other content? That and Overdubbing hate each other.

You must be recording from a Real Thing. You must be able to reach out and touch it. The USB name could be anything, so you have to pay attention. I can record from my USB Audo CODEC and that will turn out to be my Behringer UM2 microphone interface. It’s black plastic and I can touch it. I can also record from iShowU Audio Capture. That’s a audio redirection software package. It’s not a “thing” and I can’t reach over and touch it.

iShowU’s job (for example) is to create the problem you have. Make everything available for recording.

How are you listening to the guide track? One performer had his headphones up so loud they leaked into the microphone.

I think that’s all the common ways to get this error.

Does the pedal have a setting where it mixes the backing track into the show? Some interfaces have that setting.

Maybe. Doesn’t that give you a timing/rhythm error?

I’m going with a pedal setting that’s doing this. If you have a headphone connection on the pedal, you’re supposed to be able to get a good mix from that without crossing the channels.
