A Roku remote isn't attached to hdmi2, a Roku controlled by Roku remote may be attached to tv's hdmi2 input. Do you have a true Roku tv, or roku console or stick? You may have reprogram the remote to control your tv:
settings> remote & devices> remote in use> program tv> follow prompts
or if you 9.3 on your Roku:
settings>remote & devices> setup new device> remote> follow prompts
