Hi folks,

I just got a Cyber Acoustics CA-3602 2.1 system that I was hoping to use with my Vizio E390i-A1. The CA system's only input is 3.5mm and it has no remote. My TV has RCA (red/white) and optical audio outputs. I thought I could get a 3.5mm to RCA adapter and plug the audio system into the TV and be able to control the volume through the TV remote, but I haven't been able to make it work.

My TV has options for fixed and variable. Fixed works through the CA system but I can't control the volume; variable works only through the TV speakers and not the CA system.

Would I be able to use an optical to 3.5mm adapter and be able to control the volume through the TV?

If not, do I have any options other than buying a receiver? I wanted this as an inexpensive upgrade to the TV speakers, so additional equipment is out of the question.

Thanks in advance!

For anyone finding this via Google, I was able to control the volume using the remote by plugging an RCA-3.5mm adapter cable into the aux port on the speaker system.
