    Hi all,

    Hope this is quite a simple question to answer......:thumbsup:

    Is there any advantage to using a seperate optical audio cable rather than using HDMI for viseo and audio? I am thinking of buying a new AV receiver but I currently use 3 optical outs and the AV receiver I am thinking of only has 2.

    However, my current AV Receiver doesn't have any HDMI. If audio is fine through HDMI I won't need to use 2 out of the 3 optical leads that I currently use.

    Cheers in advance folks!!

    Hello emptycup

    HDMI is a mixed bag in terms of audio support.

    HDMI.org have made it possible for a Source device to Output pretty much all know Consumer audio formats (inc. the latest uncompressed HD audio codecs) over HDMI.

    Whatever you Output from your Source device via HDMI must also be supported via HDMI on the Input of your AV Amp, Display etc.

    Not all Source devices output audio via HDMI - those that do don't all support multi channel (compressed or uncompressed) so you cant easily generalise on what will be best for you without knowing what devices your system will include.

    SKY HD for example Outputs 2.0 LPCM (Digital Stereo) via HDMI and only offers a multi channel (DD 5.1) Output via Optical.

    Hi,

    Thanks for the info. My plan is indeed to install SKY HD - I didn't know it would still require an optical cable. Do you know if the PS3 will deliver suround sound/HD audio through HDMI?

    The PS3 will deliver 7.1/5.1 LPCM over HDMI - assuming your Amp is compatible with those signals!
