You miiight have to, try test streaming and talking? You should then be able to hear talking + music (just have earphones in) x
I use a headset, so not sure if the built-in mic works the same way x_x
I think it's beside the camera (the smol hole thing)
mmm with picarto, make sure you turn up the mic bars + volume bars. But if you're playing music, the mic will pick it up unless you have no earphones in
No, that's for headphones, but some Mics use a round plug similar to headphone slots but differently. It will probably be labelled, but I recommend you just get a USB one
