No Surround Sound

Hi

 

I'm running the latest PMS and PlexConnect client via my Apple TV 2 and I'm having trouble setting up DD5.1

 

If I connect my Macbook Pro to my AV receiver via optical output I get surround sound from a sample AC3 file. The sample file rotates through each speaker in turn including the subwoofer. 

 

However, whenever I play the same file through my ATV the subwoofer and rear speakers do not output any sound. When the sample file says 'Rear left speaker' the sound comes out through my front left speaker. Similar story for my rear right speaker.

 

I have enabled Dolby Digital through Apple TV in the PMS settings and turned on Dolby Digital in ATV settings. In the PlexConnect settings Transcode is set to Auto.

 

If anyone has any other settings to try please let me know.

 

Cheers

Dave

When you play the file does your receiver say dolby digital & is it set to auto detect the hdmi/optical input proper mode? Are you using hdmi or optical to hookup to the receiver? Can you hook the aTV to the tv then run optical out of the tv to your receiver? Have you assigned the hdmi or optical audio to the proper source? Your receiver should look something like this:

Hey 

Thanks for the suggestions. 

My setup is very similar to how you described it. I've tried several configurations and have discovered the following:

If I connect my Macbook Pro directly to the AVR using either a optical out or HDMI then I get surround sound using PHT.

If I bypass my ATV and use my Sony Bravia to play movies from PMS then I also get surround sound. TV connects to receiver by optical.

However, whenever I connect my ATV, either by ATV-TV via HDMI or ATV-AVR by HDMI or even ATV-AVR by HDMI and Optical I cant get surround sound.

I know my AVR and TV are ok so it must be a setting i haven't configured correctly with PMS, ATV or PlexConnect.

I'll keep experimenting.

Cheers
