Still cannot use built in mic for casting on MQDH... Extremely obnoxious oversight...

I just don't understand. Meta is advertising this as the best way to cast gameplay and yet to this day there isn't even an option to turn on the mic. You can hear the mic when you record, but not when you cast? Make it make sense. The fact that this has been a common complaint for a couple years now just makes this all the more frustrating. If /casting can do it, what's stopping Dev Hub from doing it?

Can anyone here think of a legitimate and logical reason for MQDH to lack this basic feature?
