Overdubbing recording backing track

Hi, I’m using Audacity 2.3.2 and I’m trying to record my voice on a second track, with the backing ‘track’ on the first track, however as well as picking up my voice it’s also picking up the backing ‘track’ and thus recording that into the second track as well. I’m doing this through a Behringer XENYX Q502USB mixer and I’m using Windows 10. Would appreciate any advice please.

thanks in advance…

The current version of Audacity is 2.3.3 and is available via the Audacity website: https://www.audacityteam.org/download/windows/

Are you using headphones?
Ensure that Audacity is not playing through your computer speakers.
Also ensure that in the Device Toolbar (https://manual.audacityteam.org/man/device_toolbar.html) the recording device is set to use the Behringer (probably listed as “USB”)
