I just bought this new TV. Of course the internal speakers are not great. I have attached my Logitech Z623 speakers to the audio out. They work fine except there is no remote volume control. I have to get up and turn the volume knob on the speaker. I thought this would be a common problem with an off the shelf solution. So far I am striking out. I don't know my electronic components, but I would think all I need is the equivalent of a remote controlled volume knob for 2 channels. Does anyone know of a device that can do this for me? I would hate to buy an entirely new sound system when I am happy with this only to get a remote control.
