Hi @Smeddy,
Greetings from the Roku Community!
We understand you are having a problem with your Polk Signa S2 soundbar, as there is no sound coming out. We're happy to help.
First, make sure your soundbar is not muted and the volume is at an audible level. When pressing buttons on your remote to adjust the volume, a visual indicator should appear on the TV screen that matches the volume level of your soundbar. If you do not see this visual indicator, try installing a fresh set of matching batteries in your remote and checking again.
If the behavior continues, check that your soundbar is properly connected to the HDMI ARC port on your Roku TV and that you have completed the Roku TV Ready setup process. If your soundbar has not been set up, you can expect to hear sound only from the speakers built into your TV when adjusting the volume.
One more thing to check is the input that is selected on your Roku TV Ready soundbar. If Bluetooth or an auxiliary input is selected, you will not hear any TV sound on your soundbar when using your Roku TV. You must switch your soundbar to the HDMI input anytime you want to hear TV sound on your soundbar.
If you still hear no sound after checking all the common issues, you should investigate the HDMI connection.
Please try doing this and see if it helps with what you're experiencing.
Best regards,
John
