Except...what about my speakers? Everyone dances around it. HDBaseT 2.0 is this amazing whole home multimedia revolution. But the revolution is in stereo? My TV is shown as being the only component in my room.
The reason you never see it listed is that "your speakers" are irrelevent to the discussion. In other words, the use of HDBaseT does not change the type of audio format that is used or selected. That is controlled by the sources and the sinks. The channel used between the sources and sinks, assuming it is sufficient to send all audio formats, doesn't change the audio. HDBaseT is sufficient to send all audio formats currently implemented.
The audio stream is embedded in the same data stream as the video information. The HDBaseT does some conversion but for the audio and video streams it sends the same bits as it receives.
So, how is the audio selected? Let's use Blu-Ray as an example. You can only send audio that the Blu-Ray is capable of sending. So, if you purchase a Blu-Ray disc that has DTS-HD MA and the player is capable of sending a DTS-HD MA stream (early players could not do this), then the player receives a data packet called the EDID. The EDID contains a list of the capabilities of the sinks. So, the source then checks to see if the sinks can handle DTS-HD MA. If it can, it sends DTS-HD MA. If not it sends an audio signal that the sinks can handle.
So, blame your sinks if you are getting 2.0 audio, not HDBaseT. HDBaseT is only the channel.
BTW, 3.1 or 3.0 would also be a downmix from 5.1. I know of no disc that is encoded in 3.0 or 3.1, so those signals would have to be derrived from something such as 5.0 or 5.1.
Also, any time you discuss speakers, you'll need an amplifier per channel. That is usually done close to the speakers to reduce noise. So, even if HDBaseT sent out individual analog speaker channels (which it does not), you would still have to amplify that output.Edited by alk3997 - 11/19/13 at 9:24am
