Eh, HDMI is largely replacing it, even when it just carries audio and not video.
Yeah, TOSLINK is only really necessary if you’re trying to ground-isolate your audio system. Depending on how your power is set up, you can get a ground buzz between two audio devices. Literally an audible buzz at whatever your local AC frequency is, caused by a difference in potential across the two devices’ ground connection. So probably 50 or 60Hz, depending on where you live. But since TOSLINK is optical and doesn’t have a conductor to carry a ground connection between the two devices, there is no risk of a ground buzz.
It is also great if you want to split it up/duplicate it, so have multiple outputs on one source signal. Just a cheap splitter will do just fine, and I can simply only turn on the device I currently want to use without any interference or noticable delay whatsoever. No need to tell the duplicater which device I want to use. I tried the setup with aux/chinch y-cables and it was just horrible. It is even fast enough to have the TOSLINK duplicater, then a TOSLINK to chinch splitter, than use that as input for my good old 5.1 system. The other TOSLINK channel parallely goes to 5.1 headphone sender.
Idk about anyone else but I have had nothing but problems with HDMI
EARC sucks. Constant disconnects, no audio, no video, or both.
