[AC Question]

Video chat Skype on phone - Friend can't hear music I'm playing also through phone, only my voice.

Video chat on Skype app on Galaxy S6 buddy can't hear the music I'm playing during video call out of Pandora or YouTube in the same way that Shazam can be open and hear the apps playing and do its thing. How can I fix this discrimination for my Skype experience Please? I want my friend to hear what I'm playing with the phone while I'm on video call. P.S. even while music is playing and in talking, says he can only hear my voice like some king of noise cancellation is happening. Help me ? ):

Skype uses the mic, not an audio channel, so you can't, unless Skype rewrites their app.
