My new machine seems to have problems outputting sound through the HDMI out port, but it seems fine via SCART. I have got it to work intermittantly via HDMI (i.e switch everything off and on again) and I think I have it sorted, but then when I switch the TV from source to source all I get is video and no sound again! It is the same result from DVD or the tuner, so it definitely seems to be the HDMI link that is the problem. Do I send it back??
