When I play games like GTA IV-V, Saints Row 3 or Mafia 1-3 I love to cruise while listening to the radio.

Whenever I do that my sound or video are muted on twitch.tv. Is that normal?
Is there a platform where they do not do things like that?

They even switched me automatically to a mode where my streams will not create recorded videos on their platform and for switching the mode back I'd have to promise a lot of things I don't even understand. Lawyer talk style a bit.

So... is there something better out there or are they all like this?
