Why wont my soundbar work?

[blueST]

I have a lovely shiny new LG G5 TV and I'm trying to get it to work with my existing Creative Stage 2.1 soundbar via HDMI. Whatever I do, the sound just wont come through. The TV "knows" the bar is there in some way as when I switch the bar to HDMI input the TV automatically kills the internal speakers, but the tv wont control the volume or the power of the bar via HDMI like my old TV did.

Things I have checked (with the help of AI):
Bar is plugged into HDMI 2 (ARC/eARC)
TV is set to put the audio out to HDMI
I have tried enabling/disabling eARC, no difference
I have tried changing the audio out on the TV from Auto to PCM and Pass-through, no difference.

Can anyone help? DOn't really want to buy a new soundbar when this one was great on my old TV.

I can connect by optical cable, but I don't then get the TV to properly control the bar which is a no go (my Wife wont stand for it!).

Have a dig through the settings to confirm that HDMI-CEC is enabled on the TV, this is the protocol that allows additional devices to be controlled by the TV remote.

Does your HDMI cable support ARC or eARC output?

I have an LG tv and hisense soundbar.
TV remote won't control the soundbar, but the apple tv and sky q remotes both work fine.
Not ideal, but it works.

Thanks, yes, that was another thing I have checked.

I've no idea how to check, but it worked on my old TV (ARC not eARC) so I assume so

It'd be a win if I could just get some sound to come out of it!

Appears it was the HDMI cable, but not sure why given it was fine on the old TV. I nabbed the cable off the PS5 and that worked straight away.

In the unlikely event anyone else has the same issue, the soundbar also requires eARC switched off and the audio output set to PCM (whatever that is )
