Just remember to configure your Xbox digital audio output settings to be plain stereo instead of surround sound. I have found that, with cheap adapters like that, if you forget to force the source to plain-stereo, you will frequently get just the Front L+R channels of the surround mix coming out of those RCA jacks, dropping the all-important center channel completely. So movies, netflix, and cutscenes on the Xbox would lose all the main dialogue out of the center channel.
