Setup for streaming Nintendo Switch

Honestly, I'm a little surprised that a headphone company hasn't made something specifically for this issue, as it seems that a lot of streamers would prefer to have audio from two sources. I had the same question.

The temporary solution I've arrived at was to buy a headset designed for the television. The headphone is bluetooth to a port that connects to the television through AV cables. Instead of plugging L and R into the television, I plugged one in and then plugged a 3.5mm to AV cable from my computer to the other headphone port. Console in one ear, PC in the other. I haven't had the time to check if AV splitters actually fixed the issue. Note: the headphones I bought (linked below) aren't great. They aren't bad, but they aren't nearly as quality as Turtle Beaches or Astros. https://www.bestbuy.com/site/insignia-over-the-ear-wireless-headphones-black/4219008.p?skuId=4219008

The only other option I see with searching is to set all audio to headphones, then plug 3.5mm headphones to Aux in computer to have all audio going to the computer, then you can use wireless PC headset for all sound. Unfortunately as far as I know this doesn't apply to the Switch because the controllers don't have 3.5mm ports. I'll link it anyway, maybe it will help bring new ideas to the table. https://www.reddit.com/r/playstation/comments/2taara/can_i_connect_a_headset_to_ps4_and_pc/
