As the subject says I only get sound from a column of my Sony DAV-F200 home cinema. This happens if I use FM, DVD or even my connection to the PC. This home cinema has two columns and a subwoofer. The columns are connected to the subwoofer and the subwoofer is connected to the DVD Reader. When I connect both columns to the same part, both work. In the other plug, both don't work. So, can you help with your experience and knowledge from these situations? Thanks for trying Enviado do meu Samsung GALAXY S III.
