    Hello,
    I am new to the Home theater universe and I encountered my first big issue. Here is my "setup":
    - TV: KDL-50W656A = Sony : Specification for KDL-50W656A | KDL-50W656A technical specifications
    - A/V Receiver: STR-DG820 = http://www.avforums.com/attachments/strdg820-jpg.126229/
    - PS4

    Connections:
    - from PS4 HDMI to A/V Receiver BD In HDMI
    - from TV Optical out to A/V Receiver TV 'Optical In'
    - From A/V Receiver HDMI 'Out' to TV

    My problem:
    - the optical cable from the TV has issues remaining in the optical A/V socket. It is not a stable "in" position, and the signal is lost at the slightest touch.

    My questions:
    - can this be an issue of the actual cable? Has anyone heard of similar issues?
    - A/V receiver optical socket issue? Has anyone heard of similar issues?
    - what steps should be made to fix the issue?
    - replace the Optical Cable with a new one? But what if it's the AV socket issue? I will have 1 extra optical cable (so that would make 2 of them that I have no use for)
    - buy a component audio cable and use it to output the sound from the TV to the A/V receiver? This would be the 'safest' options in my opinion, but I would hear your advice first.

    Any other suggestions are welcome, and thank you for your time.

    Did you try with a different cable or the other sockets? Or did you try to switch the plugs? (if you try the last one, probably is a socket issue).

    The design of the input associated with optical connections is poor and prone to the input becoming damaged. It may be that the input has indeed become damaged or was damaged prior to you using it. Try a different cable and if the issue is the same then conntact your retailer to enquire about having the receiver repaired under warranty.

    The optical cable connector should 'click' when it is properly inserted in the socket.

    With some types of socket, this relies on the socket cover/protector being present; so if this isn't present, the cable will never 'click' into position, and will remain loose.

    Also, on several pieces of 'kit' I've had, quite a effort was required to push the connector fully home until it clicked.

    I tried a different optical cable. I also tried cleaning the tips of the cables with an air pump. Did the same inside the socket (cleaned with the air pump).
    The result:
    - the A/V socket is damaged and the connection is unstable.

    =>

    - Repairing it under warranty will take ages here.
    - using a different A/V socket to input the TV sound (SAT) will work, but when switching to PS or ON /Off the AV will not remember the settings (SAT - > L+R) and I have to remake it every time = not an option.
    - Switching to a Component cable solution (L+R from TV to L+R in the A/V receiver) will not be that bad, will it? I mainly use the PS for Sony Music Unlimited / BD movies and the TV for SEN. The sound from the SEN is just stereo right?

    You can use the digital coax input on the AV receiver instead of the optical input. Both are S/PDIF, but you'll need an optical to digital coax convertor such as this:

    http://www.amazon.co.uk/CYP-AU-D2-Digital-Coaxial-Converter/dp/B00261SOMC/ref=sr_1_1?ie=UTF8&qid=1392319644&sr=8-1&keywords=CYP-AU-D2

    or this:

    Cable Mountain Optical TOSlink to Digital SPDIF Coaxial: Amazon.co.uk: Electronics


    optical from your source would go to the convertor and a coax connection from the convertor would then go to your AV receiver's digital coax input. Both S/PDIF optical and digital coax convey the eact same types of audio.

    Why not just use:
    - HDMI ARC from TV to Receiver (What is HDMI ARC? And What Does It Do For Your HDTV? | HD Guru I have just read about this 30 seconds ago
    -> too bad my receiver does NOT support ARC.
    - old school 2x Composite Audio from TV to Receiver? I'm not bothered by any sound quality loss because from the TV I will only play low quality stuff (am I wrong here?).

    - I also found this :SONY | eSupport - How to hear the television sound through the speakers of a stereo receiver or home theater system.

    If you are not really bothered by any sound quality loss, use the simplest solution - the composite audio.

    Depending on the level of the "quality loss" I will be bothered :)
    But in my newbie mind, having a mediocre input (SEN videos from the TV) and using a good shielded composite audio, what would the difference sound like if I were using an optic cable?
    All this is more for my 'education' / trying to find the best solutions (quality / money). A

    Well, i'm not a specialist, but I think in the rca cable you only get analogic signals and you will loose information you would have in the digital connection, like surround.
