So I want to stream a game off my Switch to Discord. I have an Elgato HD60 to get the feed and audio for other people to use, but I don't like hearing audio from my TV when I'm using headphones to chat. Besides, my headset turns off if I were to use a headphone jack so it's only for bluetooth use. My laptop doesn't have and HDMI input port and no direct microphone port, but can probably take it using my usb ports. What I want to do is have audio directly from my TV/Switch through my computer, which would then specifically go through my headphones in sound settings, since my Elgato would have a delay between the TV feed and the feed on the PC. Can't be helped, but I can't figure out how to properly get that across, since my situation is kind of specific.
I think there are usb microphone port adapters, I can't really vouch for how reliable or functional those might be though. It may even introduce additional delay between TV and PC, not much you can do with digital stuff like this.
I'm half expecting someone to vouch for those, but if it doesn't become the case I'll just settle with probably turning down the TV.
sysdvr would probably work well with this, working through USB or TCP IP bridging

i use it for both video and audio streaming personally albeit, you can just select audio and that should just stream the audio from the switch to the pc

I came across this and might actually try this, but I noticed it doesn't work with all games according to limitations. And patching currently doesn't support 14.0.0?
Mic cable from the switch to PC them use xplit to stop stop from hearing the sudio but the stream hears it
unfortunately yeah, it only supports anything that allows for you to record. i can't say much for the patches, since i don't use them personally and i'm still on 13.2.1
The Elgato has low enough latency that you could view the capture card feed in fullscreen and play through your PC. In my own testing with OBS it was good enough to play Fast RMX and if it's good enough for that game, it's good enough for just about anything.
I used hardware encoding, but that wouldn't affect the video capture, only the recording/stream. I don't think there are any settings in OBS that would affect the capture latency.
I have a HD60S. Does the HD60 not have "Instant Gameview"?
Edit: Ah, appears it doesn't. I guess you could consider upgrading to a better capture card, it would be the least janky solution, although not the cheapest...
As for USB sound cards. The cheapo ones available only have mic in, not line in which is what you want. You can use a mic in as a line in but the sound quality won't be as good, but you could get by with it. Also, it might be a mono mic in, which would be no good, you could already get mono mic input with your laptop just using a simple 3.5mm 4-pole to 2x 3-pole splitter cable. USB sound cards with line in are a lot less common and can cost a decent chunk of change, at that point you might reconsider if it's worth it just to have a janky solution to getting game audio when you could upgrade your capture card instead and gain other benefits as well like HDR recording.
There is some latency added by capturing the audio with line in and mirroring it out to your headphones, but I sometimes use my laptop as a ghetto headphone amp and the latency IMO isn't noticeable, and this laptop is a decade old.

does your laptop have bluetooth? assuming yes, then you can set it up as a bluetooth sink and connect to the Switch, I beleive discord see it as a headset/microphone so the audio can be passed through Discord via the settings if that's what you're trying to accomplish.

If upgrades are on the table, if your laptop has a mini-pcie port, you could potentially consider a mini-pcie to pcie adapter, and use a pcie card instead of a usb one. Latency will be absolutely minimal with pcie (I play off obs all the time 
I can vouch for it)
Downside is you'd have bare cards sticking out of your laptop, but if you're crafty you could get some kind of case design 3D-printed to make it look nicer and protect the internals.
Also it could be a tad bit more expensive than a usb3 card, but I guess it depends on what you'd be getting. Usb3 cards can be pretty good too, they tend to have roughly double the latency than pcie cards do though. Most people might not notice or mind the delay, but it really depends on the person (and the game)
I like the bluetooth idea from above though... if that works and doesnt have too much latency, you could have the game audio streamed over bluetooth to desktop and you can just tell obs to ignore that audio source.

It of course depends on the audio device, or maybe even just the driver for it, but a lot of laptops now days with a 4 pole plug include software that can configure the port to act as a stereo 'line in', like Conexant SmartAudio for e.g.
All of my consoles audio go through my computer since I prefer having both full control of the volume and all my audio sources through one headset/device
Unfortunately besides a capture card your next best bet(and expensive) option is the Astro hdmi auto extractor but for its price you’re better off getting a zero delay capture card, and muting (or turning off) your TV. Or just don’t hook up the HDMI out. I have all my inputs going into an HDMI switch which feeds into just my elgato and PC.
A cheaper capture card like the genki shadow cast should do the same thing in theory but I’ve never used it so I’m not sure how “instant” it really is. According to their marketing though it should be playable

I bought a pair of joy cons for really cheap, but the right side wasn't being detected by the console when attached to it, it was charging though -

NinStar:
I took a look at the rail and noticed that the two last pins were soldered for some reason, luckly I still had the rail of my broken joycon so after I swapped them I was able to use it attached to the console

I'm pretty sure I know the reason it was soldered, but I don't know why someone would do that directly on the joycon
