How do I change audio output device?

Hello, I'm just starting to use Sunshine to connect my android TV to my windows 10 gaming PC through Moonlight, and at first I had no issues, everything worked automatically.

However, lately I've been having trouble to get Sunshine to have sound on the moonlight device.
It just plays the audio on the source PC. I think it all started when I plugged in a Dualsense that was recognized as a speaker.

The problem is that I don't understand how to change the output device. I've checked the instructions available, but I have no experience with configuration this deep. I have no idea what audio sink means. I cannot see the TV as one of my output devices to choose from. I tried running the tools\audio-info.exe file and use the code that shows up for the speakers I normally use and put that into the audio sink option here:

But it didn't work.
I'm totally lost. Should I set up a virtual sink? I also don't know how to do that.

Well, I ended up uninstalling and reinstalling Sunshine and that solved it.
Now both the TV and the source PC have sound at the same time. I don't mind it because I can just lower the volume in the PC and forget about it. I still would like to understand how this works so I don't have to uninstall again in the future.
If anyone is wondering how to mute the source PC automatically, I saw a thread in the discord about it, but it requires going way more in-depth I think.
