Audacity Forum

Hello!

I am currently using the latest update of Audacity 2.3.2
My Mac OS is latest update of iOS 13.

Since updating my mac to Catalina, Audacity is not recognizing the audio from my AT LP-120 USB turntable. The program will display that it is connected, but does not record or play audio coming from the turntable.

I have checked to make sure that my privacy settings on the mac allow Audacity to use the microphone but there is still no change,

Thank you very much for your help!

Was it previously working with Mojave?
You may need to check that after the upgrade, Audacity still has permission to access the "microphone" (which means, any recording device).

Yes, it was working with Mojave and I checked that it still has permission and it does.

Are you seeing a signal level in the Mac Sound Input settings?

Yes, I am. It shows the USB device and is the signal is moving with the audio but there is no sound.

What do you see in Audacity when you try to record?

Everything looks standard other than not seeing the levels of audio when it is connected and not being able to hear or record the audio. When I click record the line starts moving but there is no fluctuation in the wave or audio being recorded.

Restart Audacity, then "Save" your "Audio device info" (see: https://manual.audacityteam.org/man/hel ... evice_info)
Please attach the device info file to your reply.

That looks OK. Perhaps the recording is just so quiet that it is not visible or audible. Are you able to Amplify the recording?(https://manual.audacityteam.org/man/amplify.html)
