I want to record the audio from my digial piano,by sending the sound to my computer with windows 10. I have bougth a normal 3,5 mm minijack sound cable. My pc (laptop) only have 2 sound cords. One is a audio output, for example for headphones, and a s/pdif cord(which i am not 100% sure what does). So how do i get the sound from the cable into one of those cords?
