Manually install audio drivers?

[Frungi]

Where do you find the option to install the audio drivers if not automatically prompted? I had audio working, but now audio will not stream, so I think I need to reinstall the drivers.

Edit: I use a software sound booster on my computer, and it seems that wasn’t passing through to the Steam Link; as soon as I disabled it, I had streaming sound. But I still have no idea how to (re)install Steam’s drivers at will.
