    Blimey, it's been a while since I've posted on here.

    I currently own the following devices:

    - Sony KDL42W653A 42" Smart TV
    - Sony PlayStation 3
    - Sky+ HD 1Tb box
    - Toshiba Blu-Ray player (can't remember model number)
    - Logitech Z5400 5.1 audio system

    Currently the devices are connected like this:

    - Sky+ HD box to TV > HDMI and to audio > Optical Out
    - PS3 to TV > HDMI and to audio > Optical Out
    - Blu Ray to TV > HDMI and to audio > Coax

    Everything works fine but, if we want to watch streaming via the smart TV then we can't output the sound via the Logitech system as it doesn't have any more spare inputs. We need the separate Blu-Ray player as the PS3 is an old model and has a very noisy fan, making watching movies on it annoying, at best.

    So, we're thinking of getting a reasonably priced new receiver and speakers, or just a new receiver and reusing the Logitech speakers which are fine for our needs. If we were to do this, what would be the best way to connect the devices? Would it be:

    - Sky+ HD box to new receiver via HDMI
    - PS3 to new receiver via HDMI
    - Blu Ray to new receiver via HDMI
    - New receiver to TV via HDMI

    Also, if we were to do that, would we still need a separate audio connection (say, Optical) between the TV and the new receiver in order to have the smart TV audio output via the receiver?

    Any guidance would be appreciated.

    Simply connect all of your devices to your TV via HDMI and then pass audio through the TV and out via its optical audio output to your Logitech sound system's optical audio input.

    If you get a new AV receiver then connect all devices to it via HDMI and then connect the receiver's HDMI output to the TV's HDMI input. You can either use your TV's optical audio output to the receiver to convey audio sourced via the TV or use Audio Return Channel (ARC) capabilities of HDMI if present on both the TV and the new receiver?

    You'll probably not be able to use your existing Logitech speakers in conjunction with an AV receiver if the speakers have an impedance lower than 6 ohm andf if there's no active subwoofer.

    Thanks for the quick reply. I didn't realise I could do that. Will there be much dropoff in sound quality or should it still be ok?

    If you have ARC then it can convey the same audio as you'd expect from S/PDIF optical or digital coax. It cannot convey HD formats such as DTS-HD Master Audio, Dolby TrueHD or multichannel PCM. It is doubtful your TV has the ability to handle such formats so your TV wouldn't passthrough such formats anyway. The quality would be exactly the same as you'd be getting via an optical connection. The only real downside is that you have to have HDMI Control turned ion onboard both your TV and receiver in order to use ARC.
