Hi folks I am having real difficulties since getting a new Philips PUS6272 tv and a Yamaha YAS107 soundbar. I was intending to connect the soundbar to the tv using both item's HDMI ARC ports, but just cannot get any sound out (despite changing the settings on the soundbar and activating the Easylink on the TV). So instead I am using an optical lead, which at least get's me some sound. However that sound is making a high pitched screech/popping sound whenever I change channels (or fast forward/rewind) on my Sky HD box. The Sky Box is connected to the TV via HDMI, so if I change the Sky Box HDMI audio output to "Normal" instead of Dolby then it stops the pop/screech, but somewhat defeats the object of splashing out on a new soundbar and not being able to use decent sound! Anyone got any ideas?
