I bought a cheap soundbar from Argos: Buy Bush 150W 4.1 Soundbar with Bluetooth at Argos.co.uk - Your Online Shop for Sound bars. I've been pleasantly surprised by the sound quality. But I have a odd problem. When watching something that has break in audio - a conversation for instance. It appears that the soundbar sought of powers down a bit and then when the audio starts again it take a split second for the audio to kick in and then you miss the first part of the audio. When listening to a constant stream of audio - music channel for instance. There is no problem. Has anybody experienced this? The audio source is a Sky+ HD box and I get the problem through the tv optical out - sound via hdmi, from the sky box optical out and through the head phone socket of the tv.
