I have an Onkyo AV Receiver (model TX-SR707). I would like to redirect audio from my system such that it will output through the receiver - without having to hook up any wires.
Similar to how I can cast from my phone (or from Chrome on the laptop) to the Chromecast device hooked into the receiver, what combination of hardware and software would I need to be able to achieve this at a system level from my laptop (Lenovo Thinkpad t440p)?
Do I need a full-blown server hooked up to the receiver using the method described here - How do I set up live audio streams to a DLNA compliant device? - or is there a more lightweight hardware device I can use?
In an ideal world, I imagine going into Sounds Settings and selecting the receiver (or some intermediary device) as the output.
I'd guess the laptop would be in a range of 5 to 10 metres from the receiver.
