Guys, I’ve done some more testing and it might be the case that I’ve overlooked something. I found out that when leaving the iPad in the living room (nearer to router/modem), I hardly have any hickups when listening to Roon over my headphones, either in the kitchen, the garden or upstairs.
Now it could very well be that this was also how I mainly tested iPeng, at least in the kitchen and the garden. So it would be unfair to blame Roon for this. Nevertheless, I do recall testing this upstairs with my iPad next to my Mac mini and it worked. Also, the Mac identified the iPad as a zone/endpoint. Now, both with the iPad upstairs and downstairs, my Mac doesn’t see it as a zone.
So there’s definitely still some sensitivity in Roon 1.4 iOS support compared to iPeng, although I think not as big as I initially put it. However, I can’t really test/compare, because Roon 1.4 seems to overrule/bypass iPeng.
