Hi all! I'm exited to try the new AirVideo HD on my AppleTV, i was very happy to buy it again, no problem with it but it seems it doesn't convert/play 5.1 audio. Before that i was using Beamer and it was converting the audio correctly.

AH ok... ehm just scrolled down for option and activate 5.1.... but why it wasn't active by default? Thanks!

Hi,

 

it should be in current version. Was the surround sound disabled, or does your video have two audio tracks (one stereo, one 5.1)?

Think the surround sound was disabled by default, I had it also.

with surround sound disabled for me the apple TV just outputs PCM for however many channels the input has.  I think I prefer that rather than the apple TV re-encoding to dolby digital.

Dont think it re-encodes to dd5.1. It re-encodes to stereo if disabled and passes thru dd5.1 if surround is enabled.

it may pass through if the dolby digital signal is compatible but it also re-encodes everything not dolby 5.1 to 5.1, even stereo input.  for example, apps such as watchespn would output stereo if set to auto but set to dolby digital it outputs a 5.1 signal.  In doing so only the front left/right have audio.  So, it does keep the stereo config but still re-encodes to dolby ditital 5.1  When streaming high quality audio from a movie I'd rather there be one less re-encoding step.

 

It's interesting to see how Air Video HD handles audio.  Supposedly the apple TV 4 only suports dolby digital so I figured that if a video had DTS audio I'd see Air Video HD doing transcoding.  But, it doesn't that I can tell.  That means the Apple TV can decode DTS, it just can't output DTS.  Again, and if this is the case, I'd rather the Apple TV just decode and pass along the PCM to my receiver rather than re-encode to dolby digital.  So, I keep set at auto.

Next update should prefer track with highest channel count for new files.

Me and the computer are sitting right in front of the tv, and the computer modem and the apple TV are sitting on the same table as the tv. What do you mean by wifi channel? Sorry, Im a dunce.
