I have: PC, Nintendo Switch, Topping E30 DAC.
Goal: Have audio from both Switch and PC (for discord and other voice) be heard at the same time.
What I have right now: 3.5mm wire going from Switch audio jack to PC motherboard Line In, routing that through Windows’ Listen To in the Sound Control Panel to Optical SPDIF which goes to the DAC.
Why I would like to change: Line In on the PC motherboard has issues because of GPU interference, causing lots of noise (it’s not the worst, but it’s constantly there), and to avoid having to use a Ground Loop Isolator. (There may be other issues stemming from the Switch DAC to Line In ADC that this may solve, but I don’t know if there are any at the moment)
My weird idea: Get a HDMI Audio Extractor to output to a Optical TOSLINK, and get some sort of Optical TOSLINK Line In for the PC, which will then be routed, along with PC sound, to the DAC.
Are there any better ways of doing this than what I have described above?
Is it, potentially, worth it?
