Sony BDP-S370 and AAC CODEC

[JamboUK]

Hi,

I am using the latest version of the Mezzmo software.

I have an issue when playing an MP4 file with AAC audio codec on a BDP-S370 Blu-ray player.

The video and audio play fine except the audio is not presented at 5.1 surround but as two channel. If I set the same video file to pre-transcode I get 5.1 (because I believe it is output as ac3). Surely the profile I am using should account for the need to transcode from AAC to ac3 when transcoding in real time? As it stands it is a manual process in Mezzmo on my server machine for each MP4 file.

The profile I am currently using is the Sony BDP, HT, SMP.

Incidentally the audio plays OK in 5.1 for the same files on a 2010 Sony Bravia KDL TV set when without a pre-transcode.

All help appreciated.
