No audio when playing a movie trailer (MP4)

WD Legacy Products WD TV Live Hub Discussions

I’ve used my “hub” now for about 3 years and love how it handles movie formats, but recently I wanted to see if I could view the movie trailers I download and usually watch on my PC.  I stream ISO format movies from my server (WHS V1) and they all work great, but I have no audio when trying to view a movie trailer.

My TV displays the commonly seen message at start up mentioning that the audio file is AAC and the video is fine, just no audio.  Is something set wrong in the hub?  My audio connects to my receiver on an optical link.

Thanks in advance …

MORE INFO & QUESTIONS …

Just tried the hub setting for audio labeled “stereo” and now (with no re-wiring of anything) I can hear the audio on MP4 files.  This brings up another question of course – Will I miss any quality in audio using this setting for everything – ISO movie streams and a few MP4 trailers.  And is the audio still using the optical link?

Thanks,

Mike

There are numerous threads and topics of discussion regarding AAC Audio Issues.

Personally i convert AAC to AC3 using XviD4PSP …

select Video Encoding > Copy (Video is not processed)

select Audio Encoding > AC3 640K Quality (Converts AAC to AC3)

Which means, neither your TV nor your amp support AAC.

I think you can go into the details for the optical ouput and disable AAC audio.  This will cause the WDTV to decode the AAC into PCM.
