Voice commands soundbar s61a

[GPeate]

I've set everything up, TV sound coming through the sound bar.

Alexa set up so I can turn the soundbar on / off, change the volume and get it to play music / radio through voice commands.

However, once I've done this I can't then seem to manage to change the source back to optical to watch TV. I've got to change the source using the remote / unit. Hardly the end of the world but seems an obvious omission. What is the Alexa voice command to do this? I've tried everything I can think of but no joy

Unfortunately I'd tried this, but it just responds " that command doesn't work on device soundbar".

Ive tried to switch it to digital input in, WiFi and Bluetooth using that command with the same resuly
