I'm really starting to get confused. I'd like to buy a soundbar to use with my TV (SONY EX710 HDTV.) For whatever it's worth, it says it has: Audio Out : Variable/Fixed Audio Out : 1 (Rear) Digital Audio Output(s) : Optical Digital Output - 1 (Rear) I have an HR21-100 with a RC64 remote and I'd really like for this remote to control the sounbar. Before I buy something that won't work with this remote, I thought I'd ask. THNX!!!
