Audio out settings on comcast box Tags: DVD Players Connection Audio Home Theatre Last response: November 12, 2010 12:59 AM in Home Theatre Share Anonymous November 8, 2010 9:47:51 PM I connected a visio soundbar 200 to my comcast box and set the optical audio out to L-PCM as per the visio instructions No sound it works with the standard audio connection More about : audio settings comcast box mrtired November 12, 2010 12:59:44 AM L-PCM tends to be the preferred setting, as HDMI-connected tv's can freak out using Comcast's AC3 signal. There has to be a key on the remote to switch the soundbar to optical. Also, and this is more comon than you think, make sure the dust cap plugs have been pulled off both ends of your optical cable.
