I just bought the Aver Media Live Gamer HD, along with a Snowball microphone. I also have my head, the logitech g930. The HDMI Coming from my graphics card ( Gtx 750 ti sc ) is going into the IN of the aver media, and the hdmi for the aver media is going to my monitor. I am able to hear the sound only if my HDMI Sound is set to default, which is not a problem because I can just mute the sound, but I am not able to hear it through my headset.
