    No Audio through HDMI


    Hi everyone
    I am trying to get audio from my PC via HDMI into my Marantz NR1402 AV Amp and then into my panasonic plasma.the plasma is picking up the desktop (so the signal is going thru the amp ok but the amp is not receiving any sound.
    In the Nvidea Control panel Set up Digital Audio it recognises The marantz under HDMI
    but in the configure section "open windows sound setting" it only shows speakers (not plugged in) & Digital Audio (S/pdif) Default device (i am showing hidden & disconnected devices).I have opened the pc case and noticed that I have a two pin cable from the 9500gt going to the Spdif on motherboard & a cable running from the soundcard to the front sockets on the pc case
    please can anyone help

    In my AMD Sabertooth you have to choose between 'HDMI/SPDIF out' in a UEFI bios selection!
    Might help

    Follow-up for ati/amd users
    - the usual cause of no Hdmi sound out is not setting the correct "default device out" in the 'Catalyst Audio' options!

    Another one is
    Are you using a 1.4/1.3c 'certified' HDMI lead?
    Others can't cope with the bandwidth needed and cause problems or don't work!

    You have to set it to SPDIF in the Windows playback settings. Reason being is that that is what the above mentioned cable is for, that and the 9500 GT has no built in audio for HDMI; it is nothing but SPDIF passthrough.
