Stereo Recording failure

Got the latest Audacity version, USB vinyl player connected to my computer. Tried to record a track from a stereo vinyl LP. But I get only one channel (sound). If play in back I get the same…just one channel of my stereo LP. What have I done wrong?

Look up in the Device Toolbar and see if the recording side (microphone symbol) is set for stereo.

Another possibility is Windows is set for mono instead of stereo. Audacity gets its sound from Windows, not the turntable.

Do you like to record internet sound? You may have to back out of those settings to make your turntable run.

See if there’s anything in that posting.
