How do I connect my iPod Pro 2 to a Smart TV?

Re: " I've just bought an iPod Pro 2 which I connected to my Mac Mini and iPhone 15 Pro without problem. But I'm unable to connect it instead to my LG webOSTV model UM7360PSA.

Is there a way to be able to hear sound through the iPods?"

Set up AirPods with your Mac and other Bluetooth devices - Apple Support

Eg: says:

"Use AirPods with a non-Apple device

You can use AirPods as a Bluetooth headset with a non-Apple device. You can't use Siri, but you can listen and talk. To set up your AirPods with an Android phone or other non-Apple device, follow these steps:

1. On your non-Apple device, go to the settings for Bluetooth and make sure that Bluetooth is turned on. If you have an Android device, go to Settings > Connections > Bluetooth.
2. With your AirPods in the charging case, open the lid.
3. Do the following, depending on your device:

• • For AirPods 4 (both models), double-tap the front of the case until the status light is flashing white.
  • For all other models, press and hold the setup button on the back of the case until the status light is flashing white.

4.When your AirPods appear in the list of Bluetooth devices, select them."
