Recording Laptop Sound

I have been recording laptop sound for many years. I have updated to Audacity 3.0.3 (Windows 10). Now after trying all combinations MME/Windows Direct Sound/WASAPI and Primary Sound Capture/Microphone Array/Stereo Mix , I am unable to record. Either there is no sound seen in the recording level or there is an infinite loop creating noise. Please help.

If your sound card has an option for “Stereo Mix”, use that, otherwise, use “WASAPI loopback”.
