Hi I’m a complete novice to Audacity and not great on computers so probably need some Janet and John advice.
I’m struggling to record from my cassette player to PC
I’ve plugged in my lead into the cassette headphones socket and the other end into the PC headphones socket.
I’ve selected MME + Microsoft Soundmapper input + Microsoft soundmapper output - pressed play on cassette and record in Audacity… and getting nothing? Just flatlining… 
I’ve turned up the volume in the cassette player and tried to switch from MME etc … but still nothing.
Please don’t laugh but I’m not sure whether my PC needs a soundcard to use Audacity? Does it? Can anyone help? 
I’ve plugged in my lead into the cassette headphones socket and the other end into the PC headphones socket.
The sound comes out of the headphone jack. 
If you have a desktop/tower computer with a regular soundcard, plug the headphone output into the line-input (usually color-coded blue). If you have a laptop with no line-in you can get a USB audio interface with line-inputs. The Behringer UCA202 is popular and inexpensive. Don’t get a regular “USB soundcard”. They are like laptops with only microphone-in and headphone out.
Thanks ever so much for response So essentially my tower/pc needs a built in soundcard?.. thing is, I’m not sure it has as I opted not to have one at the time.
Perfecto!!!
tbh I followed a youtube online tutorial and said plug into headphone in the pc - seemed strange but hey ho thought they knew better. Anyway I’ve located the blue input at the rear of the pc tower and hey presto it works!! Thank you I just need to sort out the treble/bass levels now as recording from a Walkman (bit tinny)… wish me luck. Thank you again.
