Here's the skinny on the digital output on most tvs:

If you are using the internal tuner(ATSC), then you will get DD out of the output. If you are connecting an external source like and STB, or a BD player, etc...most will not pass the DD audio out the optical port, but will pass Linear PCM...thats the way its been since the beginning. If you are looking for DD sound from an external source, you must run the audio out of the external source to your sound system...


That's a great explanation, thanx.

All hooked up and most of it seems to be working. Used the optical cable since I couldn't confirm presence of ARC.

Not sure how to explain what works and what doesn't. I may still have to adjust some settings. There is a difference in volume between sources, so I guess that could be the difference between DD and PCM.

Seems like a lot of the CEC functions are working regarding source switching and audio, but the remotes don't have full control of connected devices. Probably an issue of different manufacturers and CEC versions.

Dish, HTPC, OTA antenna and old VCR are connected to the TV using HDMI or S-Video/RCA where applicable. TV is connected to HTIB with HDMI/Optical.
