Hi @debbieward09,
Thanks for your visit here in the Roku community!
We've loved to help you out with this setup. Could you tell us if you're seeing the same behavior when not connected to any external audio devices and by just using the mobile speaker?
I've tried some of our devices here, but we can't seem to reproduce the issue.
Please keep us posted!
Thanks,
Rey
