My RX_V465 worked great with Verizon FIOS but just swithched to Comcast and now having major audio problems. Tried just running everything through the HDMI cable but sound keeps cutting in and out so I connected HDMI directly to tv and ran optical from box to receiver. Sound is great but continues to cut in and out?

Solved problem with Yamaha HTR-6040 AV Receiver. My daughter had inadvertently changed the program to "Direct Stereo" mode which allows sources to bypass the decoders and DSP processors so you can listen to 2-Channel PCM and Analog sources. Nothing to decode digital audio in this setting!

When you connect the optical cable to the ps3 you must change the output to optical on the ps3. To do this, startup your ps3 then go to settings then audio output settings and change it to Digital Out (Optical).

this sounds strange, but is true. you need to run your digital audio optical cable from your tv to your receiver (after, of course, connecting tv/receiver via hdmi). so, hdmi from blue ray to rec - hdmi from rec to tv - then optical from tv back to rec. it's round about, but that is how yamaha says (and the only way it works) to do it.

Unfortunately the RX-V463's HDMI output is version 1.2 or 1.1. In simple terms, It is useless! Not to blame yamaha or any other manufacturer but the firmware was riddled with problems; just like what you describe. There is no fix for your model for the video issue, however, the optical issue is solveable. The receiver should play 5.1- 6.1 7channel stereo etc. in optical or coaxial mode. If you have the ability to switch to coaxial, do so. it's sound is warmer anyway. Secondly, check your settings thru the receivers "GUI" or "Menu" in Manual setup for audio. Thirdly, check your samsungs "Native" resolution, chances are it will only do 720p or 1080i and; if your TV is 50" or smaller, the human eye cannot see the difference between 720p and 1080p anyway, provided you use good cables. I am a professional in the industry and still avoid using HDMI whenever possible!
Just make sure you set your BluRay and TV to the same resolution. If your choices are 720p or 1080i use 720p it's cleaner 1080i is equal to 540p, which is just a hair over std DVD video. If you still have problems and need more help, post a comment and I will help some more. Hope this helps

This usually means your receiver is not passing the HDCP copyright protection correctly. Try using component cables instead, if your receiver supports it.
