Unable to have AC3 audio while an HE-AAC decoder is enabled.

What are your recommendations for AC3 and HE-AAC?

What are your recommendations for AC3 and HE-AAC?

I dont usually do AC3, since we only have the one broadcast channel with it. With HE-AAC I use either the Arcsoft or Monogram decoders - both work well for me.

Did you include npvr.exe in your ffdshow whitelist?

That's NextPVR.exe Unless you have specific reasons like gaming I find it easier to allow all applications.

The Arcsoft one works for HE-AAC for me, but not for AC3.

I didn't have "Use ffdshow only in" ticked, but I tried that, and included Nextpvr. It made no difference.

My ffdshow says it is "ffdshow tryouts revision 3158". Is that a version which is known to work with npvr?

Yes, I know.

Its just a little annoying when they plaster "5.1" across the picture (slight exaggeration) and I only get two channel sound.

I've downloaded ffdshow_beta7_rev3154_20091209 from
http://sourceforge.net/projects/ffdshow-...e/download
installed, re-booted, and now ffdshow audio decoder works for AC3, (and the ffdshow tray icon appears), but I still have the original problem, i.e. I cannot get any sound from an HE-AAC audio stream no matter which decoder is selected for that, even ffdshow. With ffdshow selected for both, I don't get the ffdshow tray icon when the HE-AAC stream is selected, but it stays there if I go to the AC3 stream then back to the HE-AAC stream.
In that situation, looking at the ffdshow audio decoder configuration, the codecs page doesn't have an entry for HE-AAC, so no surprise that doesn't work.

So it isn't just AC3Filter, it does seem to be that any working AC3 decoder being enabled screws up HE-AAC decoding. (Strangely, having a non-working AC3 decoder enabled doesn't prevent HE-AAC playback).

Yeah - you definitely wont get HE-AAC out of ffdshow. You pretty much need the Monogram or ArcSoft decoders for HE-AAC.

There must be some other factor, because I'm managing to get HE-AAC audio when I've got an AC3 decoder enabled.

I'm successfully running AC3Filter togather with Monogram HE-AAC decoder, but I'v never had any luck combining ffdshow with other decoders. There are other available decoders that does a equally or better job than ffdshow, what do you need it for? Have you tried HD Pack or SD Pack from http://www.dvbsupport.net/ ?
