Can I use an audio amplifier?
You can connect an amplifier to the HDMI port on the Nintendo Switch dock.
- Put the console in TV mode, but instead of connecting the Nintendo Switch dock to a TV, connect it to an amplifier instead.
Then, connect the amplifier to the TV using another HDMI cable. - Open System Settings from the HOME Menu, then select TV Output ⇒ TV Sound and change the sound to "Surround".
