I would not recommend releasing a package. As of now, many user are unhappy with their roku surround system. The home theater needs a lot of fixing on firmware side. Sounds from each speaker is quite unbalance.
So work on a contract with the likes of Sony, Samsung, LG, yamaha, base, sonos, ect ect ect. It qould.make your customers happier until roku can fix its system properly. You guys have roku tvs through sharp rca and a bunch of others. I just don't see why u can't do the same for sound systems.
