    Hi, I have two 8 year old HDMI cables that are plastered into my wall and I have no idea whether they are "standard " or "high speed"

    I want to buy a soundbar and connect it via HDMI ARC - will my 8 year old HDMI cables work? is there anyway to test ?

    All I know is when I use SkyQ, Apple TV or PS3 the TV info confirms it as 1080p / 50hz - will they work please?

    This is more about my cables but my TV is a Panasonic TX55CX802B and the soundbar I'm interested in is the Cambridge Audi TVB2

    Many thanks
    Cliff

    HDMI cables - your cables pre date the 'clarity' of the High Speed/Standard labelling system.

    ARC - is supported by any 'fully wired' HDMI cable, which means most cables will support it.

    ARC - requires you to first off enable HDMI CEC (control) on the TV and Sound device, getting your system to play nice with CEC enabled can sometimes be a challenge so worth keeping in mind if ARC is your only option.

    Connectivity - are you planning on Sources > TV > Soundbar or Sources > Soundbar > TV?

    Hi Joe, yet its me again thanks for your help on my previous thread btw !

    connectivity would be a mixture:

    1. Sources > TV > Soundbar (for Sky Q)
    2. Sources > Soundbar > TV (for Apple TV and PS3)

    if it turns out my HDMI cables are too old for ARC to work, i'll have to use optical from my sources direct to the sounder or bite the bullet and get the whole lot re-wired with new high speed HMDI cables and re-plaster / decorate my wall !

    Regards,
    Cliff

    SKY Q - worth confirming the TV will accept/pass 5.1 from an external HDMI Source.

    i have a Sky Q silver box, the supported audio is:
    • Digital audio optical S/PDIF connector
    • Dolby Digital support, over HDMI and Optical
    The soundbar I'm interested in is 2.1 so I wouldn't be getting 5.1 anyway?(is what i understand?).

    My TV instructions say:

    ■ Amplifier (listening with external speakers)
    • Use HDMI2 to connect the TV to an amplifier which has ARC (Audio Return Channel) function.

      If connecting to an amplifier without ARC function, use DIGITAL AUDIO.

    • enjoy multi-channel sound from external equipment (e.g. Dolby Digital 5.1ch), connect the equipment to the amplifier. For information about the connections, read the manuals of the equipment and amplifier.

    No worries with ARC if you are only requiring 2.1 at the Soundbar.
