Electric piano and laptop through 1 set of speakers

[Agigi17]

Hello, I have a Yamaha P-95 piano and a laptop with a 3 channel audio jack (no spare jack for mic). I'd like both to sound through a simple 2.1 speaker without connecting the piano to the computer on midi signal. How can I do that?
Thank you

If you want to play either one then an input selector would work

If you want to hear both at the same time you would need an audio mixer.
