I've got a 975 preamp (and two other Outlaw devices). I've been running it in stereo with sub until I recently added a center and two fronts (moving the old fronts to the rear).
Before I changed, FM radio came in through the two speakers. I don't know about the sub; I'm not even sure FM can reach that low.)
However, after changing to 5.1, FM radio sounds only come through the center speaker. I can't find where I need to tweak it to get through at least the fronts.
Note: other things work great through 5.1. There's even a humorous sketch in one of the Halo games the clearly shows it's working (alien points to each speaker and speaks through it).
Does anybody know what I'm missing? I'm sure it's just some setting I missed or messed up, but ...
