Hi, We have Samsung smart TV and Phillips HTS. We get sound through the HTS only when playing DVDs and not on normal TV or the sat box. Been trying to make sound work on all inputs but can't get the ext speakers to work on anything but DVD player. We have put the HDMI on the correct ARC point on the TV and DVD player, set the TV to work with external speakers and also tried connecting via an audio cable on the two devices but nothing works. Tried unplugging TV for a couple of minutes to reboot. Normal TV is silent when we switch to external speakers. What are we doing wrong? Could it be our HDMI cable is not the correct type? Or are we expecting too much from the system? Thank you in advance for any suggestions you may have........cheers, Kate
