I have read posts over 4 years old about sonos playbar not supporting Dolby Digital Plus. I find it amazing that sonos does not clearly state this or even better found a solution. If a conversion process is not possible then the conection mechanism should be changed to hdmi.
I phoned sonos and the operatives are not really awarevof this issue. If sonos want to be in the 5.1 home cinema market this is a must!!!!
I would like to see some meaningful response from sonos that addresses the issue and does not just fudge the ussue since it was first identified over 4 years ago on this site.
