It seems you don't need to switch.
First , before I'm asking questions I'm gonna tell you why I'm doing this ...
I'll buy new headset and it's called steelseries h it's wireless , so i want this headset working on my ps4 but if i want to watch some youtube videos or Netflix etc , i have to connect my laptop through HDMI cable to my tv (and the model is sony w800b by the way) to listen to tv using the headset .
now the question is how can i done this without being every time switching Between them ? And is it even possible to use this headset or astro a50 hook them up directly to tv ?cause i never try this at all
I done some research about that and find something called switcher and splitter and of cours two of them using the optical for sound which is what i want however , i don't know how or which one i Need to use , if this gonna work it will be so helpfully for me .
