DirectShow Graph problem

[Cifou]

Hello,

Here is what I'm trying to do :
I have a MKV containing a RV9 or RV10 stream and an AC3 stream and I want to play this within WMP10 on a WIN XP.
The problem is that I want to send the AC3 stream directly to my A/V Receiver through
the S/PDIF optical output of my PC to get the stream decoded by the receiver

Using Media player classic (with correct passthrough configured) works fine.
using WMP10 : no way.

I installed AC3Filter but I did not have more chance with it.
Using Graph edit, here is what I get (can't be more simple) for the audio part :

Initial rendering (does not work : black screen)
Source file -> Matroska splitter -> AC3Filter -> Default Direct Sound Device

2nd try - change the audio renderer in GraphEdit : WORKS
Source file -> Matroska splitter -> AC3Filter -> Realtek AC'97

3rd try - Switch back to Default Direct Sound Device in GraphEdit : WORKS !!!!
Source file -> Matroska splitter -> AC3Filter -> Default Direct Sound Device

Is there a way to change the "merit" of the audio renderers ? Or Am I doing something wrong ?

Help, I'm really getting crazy with this thing !! :confused:

You can select the default audio renderer in AC3Filter configuration dialog, it's on the "System" tab.
Select "WaveOut" and see if this solves your problem.

Thanks Rigel,

You were right, I turned the radio button to Wave out and now it works well in GraphEdit.

Unfortunately, It's still the black out in WMP10. When I check the settings of AC3Filter in WMP10 (options/DVD/Advanced), the input received by AC3Filter is : PCM 16 2/0 (48000Hz). In GraphEdit it was the correct value : AC3. So the AC3 stream is lost before reaching AC3Filter

So it's seems that "something" gets into the party between the Matroska Splitter and AC3 Filter when used from WMP10 !!

Is there a way to see the graph used by WMP and/or control it ??

Thanks again for your help.

I don't even have WMP10, so can't comment on it.
But why exactly do you need to use WMP10?

[Cifou]

As far as I know that's the only way to have a good integration with software such as Media Portal or myHtpc (now Meedio). They all use natively the WMP component

But the problem I have was with WMP9 as well (that's why I tried the 10). I'm starting to believe that WMP is a real crap thing. There is no setting, that's hard to find what's going on...
