Where can I find a universal remote that can control a Sony SA-VA1 set of powered speakers? My wife hates having to use multiple remotes and just sets the sound to use the internal TV sppeakers on the Sony WEGA KV-40XBR800 TV. The Sony TV remote can't seem to control the volume on the SA-VA1 speakers. She has asked for a universal remote but I can't find one that mentions the SA-VA1 or the RM-VA1 remote that controls the speakers.
