Sorry for the length of this post, but I wanted to get everything down in one hit and I REALLY need some help as it's driving me nuts!
I have been happily connecting to my RX-V675amp from my Macbook Pro with no problems since I bought the amp a year or so ago - connected through iTunes > Airplay and it also appeared as a device in my System Preferences > Sound menu. I was using the Remote app on my iPhone and was always able to connect, but I think that still routes through iTunes/MB rather than the iPhone itself.
Connecting to the amp directly from my iPhone and iPad has always been flaky - sometimes I would see the amp as an Airplay device but many times I wouldn't. However, I noticed the other evening in iTunes on the MB that the Airplay menu had turned orange, but I wasn't using it so didn't think anything more of it. Since then I've tried to connect and the Airplay option no longer appears, nor does the amp appear as a device in the Sys Pref > Sound menu.
I also have a Synology Disc Station with the DS Audio app and if I use this I can connect to the amp via Airplay. Both the amp and MB are hard wired on my network, plus I have checked my router a number of times and the amp always shows up as connected (plus I can ping the amp and access its web console from a browser on my MB), so there is nothing wrong with the network connectivity of the the devices. I've tried renaming the network as suggested above just in case, but still cannot see the amp from iTunes or iPhone, but can still connect via DS Audio app. I've also updated both OS X and iTunes with the latest updates, but still no difference.
Even though I can connect via DS Audio, the app itself is a little clunky and I would really prefer to use Remote/iTunes as it is much slicker and previously worked a treat. Does anyone have any other suggestions? Any help would be very much appreciated as I losing a lot of hair over this!
Thanks,
Kevin
