1 – Go to pair a Bluetooth Audio Device on your switch
2 – Turn on Bluetooth in your PC and search for Bluetooth Devices in the Bluetooth & Devices page in Settings
3 – Connect to your Switch by clicking on it. It should pair but the Switch wont detect your PC as an audio device.
4 – While the Switch is connected and waiting but before it times out and disconnects, download and launch [this](https://www.microsoft.com/en-us/p/bluetooth-audio-receiver/9n9wclwdqs5j) program from the Microsoft store then click open connection on the Nintendo Switch device listed in said program.
5 – If all went well your Switch should now detect your PC as an audio device, allowing you to capture and listen to your Switch’s audio over Bluetooth. It will output the Switch’s audio to your default audio device.
For me, the latency was a few frames and was noticable after testing with a charger in Splatoon, but only just. If your Bluetooth chip is a bit better it could be even less noticable, and it’s also worth noting that the audio quality compared to using wired headphones (or connecting the Switch through line in and listening to that) isn’t as great.
What uses do you think this could have?
