Samsung 46c610 Dolby Digital out?

[Ricky12345]

Hi,

When selecting the SPDIF output (PCM or Dolby Digital) the Dolby Digital is greyed out. I have HDMI HD cable box plugged into it. Any reason it only lets me choose PCM?

Thanks very much.

It's not that common for TVs to pass Dolby Digital audio through from an HDMI source to its optical connection, if that's what you're trying to achieve.

You will probably need to route an audio cable direct from the cable box to your sound system.
