Hi Wolf. I just picked up a TCH1 recently and it is working for me on iOS5. I only have 6 zones, no idea if that might make a difference. Does the admin part work OK?
I must say I'm disappointed by Russound too. Being a software guy I see so much opportunity for them to put a better front end on their products and keep improving them but it looks to me like they get it out the door, issue a few critical fixes then pretty quickly kill off any maintenance activity. Classic example (and yes, I'm having a rant here) is the SMS3 - the web user interface is laughable - some kind of 90s jukebox looking thing. Quite apart from the looks though, it basically doesn't work properly with new browsers (hangs when I click "Music" in IE9, went back to Firefox 3.6 and it works perfectly) but I see no sign they'll fix it. As browsers evolve whatever odd methods it uses are gradually crippling it as I guess they are not standards-compliant. At this rate the SMS3 browser interface will be dead soon. Oh, and it doesn't work at all on the iPad either.
Oh, and on the subject of both the TCH and Russound software, why on earth can I not type when I am searching for artists/songs etc on my iPhone? I have a perfectly good onscreen keyboard but instead I have to arrow up and down through 26+ characters and then arrow to the next character?? Not surprisingly this isn't in the brochures and again, it's laughable. I don't care about the "whys", this just isn't good enough in this day and age.
Who on earth builds this software??? Have they ever watched anyone use it? Russound, is this really news to you, do you even care? There are people out here who can help, this isn't so hard. Hell, if you brought out a feature-packed upgrade for TCH, SMS etc I bet there's plenty of people who would pay you for it, I know I would.
