Or even worse, fake stereo!
Apart from that, laptops, and newer computers for that matter, can be a challenge to get them to co-operate. For some reason, they try to be difficult to set up for input (that mono sound in socket for example!). Getting Audacity to work around Win 11s little foibles can be a bit time consuming too.
I've not tried transferring lp's recently, but I do record streams from BBC Sounds and youtube for later listening on a Dell Inspiron with Win 11. My Audacity is set up with the Audio host as Windows WASAPI, the Recording Device as speakers (loopback), Recording channels 2(stereo) and Playback device (speakers). It works for me....
