Hi @LewStewel,
Thank you for posting here in the Roku Community!
While Roku TVs don't have a dedicated setting to adjust sound levels directly between individual inputs, you can utilize the "Automatic Volume Leveling" feature within the audio settings to achieve a more consistent volume across different inputs, including when switching between channels or content with varying audio levels; this essentially levels out the sound between different sources.
We hope this helps.
Best,
