Thanks for the post.
Please be aware that Roku device remotes do no support control of non Roku soundbar devices, only TV power and volume when paired properly.
Have you tried re-pairing your remote to your TV to see if that resolves the issue you are experiencing with your TV volume? For more information about how to pair your remote, visit our Support pages here:

Why is my Roku® enhanced remote not controlling volume and power on my TV?
Please keep us posted what you find out.
Thanks,
