Connecting to Distant USB or SPDIF

My headphone DAC/Amp is in another room and has either a USB or SPDIF (opt or coax) input. Is there a simple and cheap way to connect it?

Add a Chromecast audio.

A lot of people use an RPi with a DietPi or Ropieee OS and either Ethernet (preferred) or WiFi.

I ordered one. Thx for the tip. I also ordered their 3.5” to Toslink cable as I have no 3.5” input.

I’ll look into them. First I’ll see how the Chromecast works out.

Realized I was missing something, like the roof over my head. I’m now aware of several solutions. Thx to all.
