AAC 7.1 TO 5.1 dts/dolby?

post #1 of 11
Thread Starter 
ok guys ive connected my home theater 5.1 system to my pc using the SPDIF. everything works fine with the combined community codec pack expect a video file i have that uses 7.1 aac audio, my system is dolby or dts. so playing the files it sounds distorted. Using the libavcodec it plays dowmixed digitally but at a very low bit rate (54kbps)

any thing?

easiest way would probably be to incorporate ac3filter into your list and have it live encode/transcode aac to ac3 and then pass that through to your avr to be decoded.

You can either use ac3filter for all audio, or just let it handle aac.

I personally don't run this way anymore, so I cant really be more specific. Now I use LAV filters w/ MPC-HC and have everything decoded to PCM which is outputted multich to my receiver via HDMI.

dang it rmp459, you beat me too it. I just wanted to make sure he was not running xmbc. But if you follow his advice with the ac3filter you should be fine, I also run the LAVfilter and run through MPC though Media Portal and to hdmi and have no issues.

If you want to use AC3filter in Media Player Classic, you have to disable MPC's internal AC3 and DTS decoders.
I believe you go to menu View-> Options -> Internal filters and uncheck decoders for formats you want to passthrough.

Now don't hold me to that, this is along time ago for me.
