No dolby digital sound when watching Movie in MP (1 Viewer)

[Kariya]

Hi,

I just connected my media center to my new AV receiver Denon 1912 to be finally able to listen to DD 5.1 sound.
Therefore I connected my media center via HDMI Output (of my ATI HD 4550) with the receiver.

I did not have any problems when doing this except the fact that I only hear a stereo sound when I watch a movie within MediaPortal. The strange thing is that everything works fine when using the VLC Media Player, so I guess that my problem is related to the Codec used in MP.

I'm using SAF 5.02 and specified the FDDshow audio decoder as MP audio decoder:

I already tried different settings in the FDDshow audio configuration but without any success so far. Here are my last settings that I tried:

Does anyone had a similar problem or can help me the correct Codec settings?

Thanks in advance.

Michael

Hello!
I don't see much wrong to be honest.
Just two things you can try:

• In MP Config -> Video Codecs set Audio Renderer to "Default DirectSound Device"
• In ffdshow config you can try to tick "Connect as PCM first" and untick "AC3 (S/PDIF encode mode)"

EDIT:
Maybe one more problem. Could post a screenshot of ffdshow config in Tab "Codecs". Make sure AC3 and/or DTS is not set to disabled..

Hi,

I tried both things mentioned above (Audio Renderer to "Default DirectSound Device", set flag "Connect as PCM first" and remove flag "AC3 (S/PDIF encode mode)") but without any success.
The option "Connect as PCM first" made the problem even worse since there was a strange tone coming from all five speakers instead of only providing stereo sound when playing a movie in MP. The only positive aspect is that the strange tone came out of all five speakers

I also checked the FDDshow codecs and AC3 and DTS are enabled:

Any other ideas?

Thanks and Regards,
Michael

Strange thing.. maybe you should try another audio codec for MPEG/AC3 Audio. (like LAV or AC3 Filter for example)

I just installed AC3 Filter and replaced the FDDshow audio decoder in MP Config.
Now, it works as expected. I still don't understand why it didn't worked with FDDShow but I don't care anymore

Thanks a lot!

Thanks a lot!

Just remember that AC3filter can't pass HD audio, LAV can

Hint on issue: did you check if your Windows speaker config is set to 5.1?

Thanks for the note, I just installed LAV to replace AC3filter and this also worked.

My windows speacker config is already set to 5.1.
