Roku TV-Roku Streaming Soundbar-Uverse Box

When I set up the soundbar, it connected via my wireless connection.  I do have a gateway right there and it is wired directly to the uverse box.  Then the whole menu was totally new and missing the Uverse box.  I could only hear sound from the soundbar and there was no picture.  It seems the soundbar and its built in streaming service overrode the existing Roku TV features and my uverse.   Do I need to have just a simple soundbar without the added features of the roku brand and its streaming ability?  I disconnected it and then attempted to plug in some speakers using the basic audio jack but no sound came out of those and the Roku app did not recognize those as a valid input to the TV.  I had just disconnected an older 2006 home stereo system and wanted something streamlined like a soundbar.  But now it's a mess so I'm back to square one.  Can a streaming soundbar be paired with the Roku TV that is hooked up to the uverse box?  Any help appreciated!
