i have a query regarding aac-lc 5.1 audio. here's my situation, i've converted some of the apple 720p trailers to xvid 720p using the settings i usually use for smooth running 720p on xbox. the original trailers use aac-lc 5.1 audio, so i tried keeping these streams in their original format to avoid having to recompress them. i realise xbmc will transcode in realtime to dd 5.1 and it does a great job of it, however after playing these trailers for a minute or so (depending on the hard disk cache setting size) they eventually start stuttering. to make sure it wasn't the video encodes i transcoded the audio to dd 5.1 and the resulting files play perfectly. could this be pointing to some kind of memory leak in regards to the aac 5.1 playback? i'm actually at work at the moment so can't provide a logfile, but can add this when i'm next there.

if there's any other information i need to provide please let me know.

edit: wasn't sure if this belongs under support or bug discussion so please feel free to move it if necessary.

also if needed please let me know and i can provide a sample file.

well aac (both he and lc) are more cpu intensive. i would think you are just running into a xbox cpu limitation.

if it was a cpu limitation wouldn't the playback be stuttery the moment it starts playing, not later into the file?

How you manage to get your AAC LC sound out?
I've the problem of not playing any AAC LC audio on XBMC live (Zotac ION). I have Sony 5.1 Home Theater connected via digital coax output and set XBMC to do digital output. I get only rear surround effects in my speakers. Played with all settings, don't know how to solve it. Does XBMC suppose to decode AAC LC to PCM uncompressed streams and send to receiver?
can you share samples?
