When i stream PC games I use a set of astro a50s. A feature they have is that they have two sources in the headset, and optical (for game) and a USB, (for mic input and voice output). So when I attempt to stream I can either only have game sound or voice (skype/teamspeak/mumble). Is there anyway to add another audio source? I have tried using Virtual audio cable but it hasnt worked and I have also tried DirectshowAudioSource
