I have a very specific enquiry on volume control with powered speakers, namely via a TV remote. I have a slew of old 5.1 and 2.1 PC speakers, some of which are actually pretty good. Rather than shell out on multiple receivers + passive speakers + new subwoofers etc, I'd like to repurpose them for use on the TV's around my house. I don't particularly need surround sound either for the rooms these will be in, so that's not going to be an issue. I already tried this, however, it was pretty impractical because none of my TV's have 3.5mm inputs, and hence I can't control volume via my TV remotes. After some research, I realised I'd need receivers with both HDMI inputs and pre-outs. However, these receivers are rarer than I thought on the used market. Are there any cheaper/simpler alternatives to volume control that would work via my TV remote, or are receivers necessary?
