    I've got one of them sitting in a drawer. Wonder if they work? Do you have one working, Bill? I bought mine because Sony made the same mistake with the BDP5100, no optical out. Ended up tossing it in a drawer and using a Sammy E6500 that does have an optical out port. All this to get Amazon.

    Sorta made a mistake when I bought a Sammy sound system a few years ago that doesn't have the HDMI option. Would have just chucked the Sammy, but it is a really good sound system aside from the lack of HDMI connectivity and fits into my master bedroom perfectly. I expected a "tinny" sound system and a quick return, but I got sound quality with that thing that has to be heard to be believed. And it has a passive subwoofer that actually works. 3 ohm speakers. 160 watts. I've got several optical switches and I've used one of them.

    Seems like the makers of many devices are trying to phase out optical outputs for some reason. Wonder why?

    Lack of electrical interference on the optical cable

    Optical cable can't radiate RF

    I have a cleave tool and connectors and a roll of cable, I love making them!

    Handy to have at least the red glow leaking out the connector when I am upside down behind a cabinet and otherwise would not know the power is working.

    Weird, I've seen pets chew on coax and power cords, never seen one gnaw an optical cable.

    My old Kenwood receiver (gawd it's a beast) had 7 (!!!) optical inputs and IIRC it had 2 out !!

    The uber cool factor of having light carrying my Dolby Digital thru a flexible cable !!

    Fun to pimp clients by telling them never to put active cable up to their eye!

    :coffee

    Not sure what you mean by your post. I was asking why optical outputs are disappearing. Sounds like you like optical as much as I do? Puzzled, I am.

    It actually costs more to have optical. The only reason it was pushed hard over coax was marketing and accessories it could be sold as well and it was less confusing because optical only fits optical. Now with hdmi audio they are dropping optical since it costs more and they feel two digital inputs per source is enough. My guess anyway.

    If you step on them they're pretty easy to break. That might be one reason.

    Sure seems as if they jumped in with both feet. It's getting hard to find stuff with optical ports.

    We wondered why optical was being phased out and I snarkily posted many things I like about optical, and since the industry loves to change things we frequently like, that is probably why they are getting rid of it.

    Optical cables are being dropped because they are obsolete. The industry wanted to move to a single cable solution (audio + video). S/PDIF does not have the bandwidth. In fact, S/PDIF does not even have the bandwidth for the "new" audio formats (Dolby TrueHD, DTS HD Master Audio, and Linear PCM). They are also dropping RCA analog cables and digital coax as well. We live in an HDMI world now. Time to get on :). Also, HDMI is the only standard that supports secure connections.

    To comply with HDCP, most TVs will not output true surround sound via the optical output jack from an HDMI source. They will usually convert it to some sort of downmixed stereo format (simple 2-channel PCM or Dolby Surround). The optical out is mainly useful for using the built in OTA HD tuner, or built-in Smart TV apps.

    Nah, thast not it at all. How often do people unplug their cables and leave them lying around to step on. Its all about cost as usual. Add in what Sledge said, and that's really all there is to it

    this has nothing to do with HDCP.

    Not sure why they do it, but it is true. Reviews of new
    TV's at hometheater.com is about the only place this is exposed.

    It has to do with the fact that FULL QUALITY BluRay is only allowed via secure connections (HDCP). This is not really a technical requirement, but more of a licensing requirement from the studios (no HDCP, no content. PERIOD. END OF STORY). Optical doesn't support HDCP or security of any kind nor does it have the bandwidth to do the video and/or audio.

    Why are we even talking about this anyways lol? Optical has issues. Like jitter for example.

    In this situation the CSR should of make a note in the work order, But would of said that its not guaranteed which specific model one will get, and can only be confirmed with the tech when he calls before his arrival, It all depends on availability from your local installer.

    You should see my wiring mess. When I have to get behind one of the TVs or one of the DVRs or one of the DVD recorders or players I'm stepping on piles of wires. I use 5 of each type of unit.

    HDCP is not the reason at all. The reason TVs downsample Dobly Digital to PCM when outputting to the optical port is becasue the manufacturers are cheap. In order to take Dolby Digtal off the HDMI input and send it out over the Optical input they would have to decode the stream and then recode it to work for optical. The TVs have the decoders built in because they need it to be able to play the sound, but most of them don't want to have to pay for the hardware/software and licensing to be able to recode the Dobly Digital signal to be sent out over optical, so instead they just send it out as PCM. There are some TVs that do offer this feature, but it is usually only the higher end TVs where the manufacturers are more willing to spend money on other bells & whistles.
