Clicking the software playthrough button creates feedback

Upgraded to a mixer for my podcast and noticed couldn’t hear anything in the headphones. Did a little quick research and found out I needed to click the “software playthrough” option under preferences. Once I did I immediately noticed loud feedback in the headphones. What did I do wrong, any advice? Looking to better my podcast with your help.

Thanks
Eddie

There would be no feedback if Audacity is recording the mixer (you didn’t say where the headphones are plugged in). If you like to record internet audio, you may have left the recording coming from Stereo Mix which is “Everything Playing on the Computer,” not the mixer. That is a feedback loop.

Look at the Audacity Device Toolbar and make sure your mixer is selected for recording.

How did you plug your new mixer into your computer?
