The app uses WASAPI to get sound. It could be problem with some sound cards if your media player uses directsound or asio for example. You can try to change player output to WASAPI Shared. Or you can enable 'stereo mix' in the system and use microphone as source in the app. Unfortunately I failed to fix this problem programmatically.
I Unfortunately cant get the app to recognize my Stereo Mix, which is frustrating because I had it working in my live stream a while ago. has there been any fix to System audio yet? any tips? I'd Humbly appreciate it.
