This question comes up from time to time and the level is fixed level. It's not a feature in most if not all Samsungs.

Hi,
I have Samsung smart TV Model: UN46F7500AFXZA.
I have connected Logitech Z623 speaker with Audio Out (3.5mm jack). Speaker plays TV audio nicely. When I change TV volume it does not change speaker volume. It just keep on changing its own volume and both TV and external speakers are playing same audio.
Any idea why this happening and how can I control speaker volume with TV volume?
Let me know if you need more information.
