My build has been stable for years. Suddenly my feedback has stopped working from my AVR to my Ipads, no more volume value or mute on/off indicator.
Running Irule ver 4.3.1 (4290) on Ipad gen 1 ios 5.1.1 and
Irule ver 4.7.1 (4846) on Ipad Air running 11.0.2.
Where should I start to try and diagnose/fix this?
