    'Can't play test tone' Error After Installing Windows 7 with Radeon HD 4870

    bytor

      Hello everyone. I've just done a fresh clean install of WIndows 7 after happily using Windows Vista for years without a problem.

       

      For some reason my HDMI sound has gone. I've tried everything - reinstalling CCC, disabling my sound card speakers and HD sound, uninstalling my sound card speakers and HD sound but still no dice. Whenever I try to test the sound via the Playback dialog box I get an error saying "Can't play test tone'.

       

      I know that the cable works fine as I've tried it on a friend's PC.

       

      ANy help would be very much appreciated. Cheers!
