If you go to viewsatusa website they have a new version of the firmware, I haven't tried it yet to see if it works the ac-3 sound. I think its version 1.24
, the 1.22 that was up there for 6months or more never did fix it. I gave up, after hounding them for 4 months, earlier this year. I bought a traxis 3500, which does the ac3 now, and blind searches faster than the Ultra (and just about any other fta rec lol)
There is a new model Ultra, that has a Samsung processor, recently released, that is using a vers 1.31 firmware. I read about it on another site, firmware is supposed to be compatible with the original Ultras and the new model, unk if it fixes the sound prob or not. That isn't up on the VS support page yet.
