Hi, @Rlt1024.
Welcome and thank you for posting here in the Roku Community!
We see that you have a question about why your Roku TV doesn't have a volume-leveling mode. No worries, we're here to help.
A Roku TV system only supports volume modes when Roku wireless speakers are connected. If you have a Roku TV system, you may be able to adjust manufacturer-specific sound modes. When you are using a Roku audio device, you may be able to configure additional audio settings like sound modes, speech clarity, and expanded stereo.
Moreover, you may visit this support article on how to use volume modes on your Roku streaming device
We hope you'll find this information helpful. Let us know if you still have any questions.
Regards,
Reynan
