Getting MPC-HC to work with Cyberlink Audio Decoder

[daanodinot]

Hi,

Recently I discovered the phenomenon Dolby Headphone. I was really impressed by it so I thought I might give it a try. First I tried PowerDVD (which has a decoder build in for Dolby Headphone). The problem with PowerDVD was that I couldn't get dxva to work. As a result, my CPU was fully utilized and couldn't handle the load.

After that, I decided to give MPC-HC a try (which's dxva has always worked well for me). I followed a guide (http://www.head-fi.org/forum/thread/405417/guide-dolby-headphone-in-mpc-zoom-player) but unsuccessfully. I added the Cyberlink Audio Decoder and blocked all the audio decoder filters I could block. Still, the internal AC3 Audio Decoder always shows up in the filter list when playing a movie, even though I unticked it. In order for Cyberlink Audio Decoder to work it should be the only audio decoder actively used.

So the solution can really be both ways... getting dxva to work with PowerDVD or getting the filter to work with MPC-HC (although I prefer the latter solution).
Hoping for some suggestions, thanks!

Have you disabled the AC3 Transform Filter in Internal Filters?  That is the decoder which is built into MPC-HC.

Yes I have. I've done everything I could think of to make it work. In the end I decided to try the PDVD9 codec. For some reason that worked... Not a proper solution, but it makes me wonder if the latest codec actually works in MPC-HC.

Have you tried to make gragh in GraphEdit/GraphStudio? Does it work? Maybe you'll need Cyberlink Demuxer as splitter. But first try to increase merit for CAD.

Increasing the merit of the CAD didn't help. I've also blocked 3 other filters, after which the "DTS Decoder (low merit)" was used.
 
I also tried Cyberlink Demuxer as a splitter (which gave me an Active Movie Window). After blocking 4 filters, I ended up with the MPEG-1 Audio Decoder (low merit).  
 
I could try GraphEdit, but I've a strong feeling it will not work anyways. Clearly the CAD is somehow unable to work with MPC-HC...

I managed to get this working and wrote up a guide here:

I think it may only work with particular versions of the CyberLink decoder. I believe after a certain point they modified its behaviour specifically to stop people using it with other media players. However, it was still quite difficult to get it working for audio types other than DTS, because the existing guides were based on Windows XP, not Windows 7.
