I am using an Audio Authority 2800 Series HDMI over IP video distribution system. It works perfectly when getting a feed from a TV receiver. But when I connect a PC, there is no audio. If I connect the PC directly to a TV, there is audio, so I think the PC's HDMI setup is basically OK. The 2800 system supports only 2 channel PCM, so I assume that the PC is somehow sending something that is incompatible. Basic Windows sounds also don't work, so it's not just a video encoding format on the PC. I'm surprised that the PC HDMI autoconfigure handshake doesn't sort this out somehow and send the proper 2 channel PCM audio.
1. Is anyone else using a PC over this type of system?
2. Is there any way to force the PC to send 2 channel PCM audio?
