Samsung HW-K450 - no sound on HDMI input

Current setup of LG C1:
HDMI 1, 3 & 4: Xbox, PC, Chromecast -> LG C1 -> Samsung K450 sound bar via eARC channel
HDMI 2: Nintendo Switch -> Samsung K450 sound bar -> LG C1

I have no audio issues with HDMI input 1, 3 & 4.

On HDMI 2 however, the picture from the Switch goes to the TV, but no audio comes out of the sound bar. If I power on the Switch, the TV changes to HDMI 2 and the sound bar changes inputs from D.In (ARC) to HDMI. If I change the C1's input to another source, the sound bar changes back to D.In (ARC). While on HDMI 2, the sound bar will go to sleep after a couple of minutes, I'm assuming because it does have any audio going to it.

Any ideas on a fix?

If the TV and Soundbar are both eARC enabled you can try disabling HDMI CEC control.

If you need to retain HDMI CEC control try connecting devices to the system in a different order.

If you need to retain HDMI CEC control you have to remember that the TV is the 'Hub' in a CEC system and you have no way to adjust that.

When you connect devices to the TV with HDMI CEC control enabled the TV creates a map devices - it can be useful to add devices one at a time and allow a few mins before you add the next device to allow the TV to create the CEC map.

TV has eARC but sound bar only has ARC. Worked fine when I set it all up a month ago. Not sure what would have changed to break it.

LG TV - which Input is marked eARC/ARC and do you have that connected to the ARC socket on the Soundbar?
