Hello, I'm having the same issue. I have wireless surround headphones with a transmitter which works like an hdmi hub (sony mdr-hw700ds) . In order to use as few cables as possible, my blu-ray player and a modem with tv service are plugged into the transmitter using hdmi inputs and the hdmi output of the transmitter is plugged into the hdmi input of the soundbar. Then the hdmi output of the soundbar is plugged into a videoprojector. Still there? ;) The aim is to either use the soundbar as the main speaker when watching movies or the headphones when someone sleeps in the bedroom next to the living room. When using the soundbar, everything is fine as the transmitter can work in passthrough mode even in standby. My problem is when I use the headphones, it seems that only the video signal is sent to the soundbar, as the audio signal is sent to the headphones only (apparently). Meaning that after 15 minutes the soundbar automatically switches off and the video signal received by the projector is lost. As a consequence, every 15 minutes I have to power on again the soundbar in order to retrieve the video signal, which is really really annoying! If only the soundbar could work as my headphones transmitter, so even in standby mode the signal could still pass through it... So please samsung techs, release a firmware update to remove this time limitation or allow signal transmission in standby mode, I want to watch a movie longer than 15 minutes!!!
