Welcome to the Roku Community, @Kahonu84!
We appreciate you reaching out for support about changing the audio on the NBA channel. We'd be more than happy to help.
During playback, you may press the star (*) button on your physical Roku remote to open the Settings and change the audio to your preferred one. Also, if I understand your other concern correctly, you can return to your Home screen by pressing the Home (which looks like a little house icon) on your remote. If you want to return to the NBA feed, press the Back (⬅️) button.
Feel free to respond with more information if you need any further help.
Best regards,
Carly
