Lightbulb HDMI audio out?

I recently purchased a surround sound system but it doesn't have an audio out. I want to send an audio output to my Russound multiroom audio controller. It does have a HDMI out.... can I get just an audio signal from the HDMI cable? If so, how?

Thanks.

Okay. I have the HDMI cable and pinouts but it doesn't show which ones are audio. Any help would be appreciated.

Thanks.

What kind of home theater system did you get? What most home theater systems have is a setting, usually in the audio menu that allows you to turn on/off audio output from your home theater system. There are some that will not pass audio at all.

Smile Re: HDMI audio out?

HDMI is strictly digital. http://www.interfacebus.com/HDMI_Pinout_Bus.html#top shows a pin ID of the respective pins of an HDMI connector. From what I remember reading, the digital signals passed by HDMI have copy protection encoding. So, in order to extract the audio portion from the cable, it would first have to be fed to and through a component with an HDMI input. The component must have copy protection encryption capabilities, a D to A converter, and RCA output jacks. In other words, for all practical purposes, the answer, in this particular instance is no. My suggestion is to get a separate AV receiver that will accept HDMI input and has separate analog audio output capabilities. Hope that this has been of some help.
