Diana thanks for the reply, your idea is a good one, but for me it is a limited but may be the only workaround
I Have sudden hearing loss in one ear. Without BT i am limited to the single preset volume level programmed into the HA by the costco tech. This is because the button on my HA only allows manual selection of program levels by clicking on it and not volume levels.
if I want more than one volume level I must use BT paired to my iPad and the ios app or the much better free costco iOS app called Choice to set any volume levels on the fly by a slider (which is great! ). The apps give better control over program settings too. I knew this when I bought my HA because I always have my pad. All has worked perfectly except for this Apple Tv issue
apple TV is also BT paired to my iPad and both Apple TV and my BT paired HA appear on the AirPlay menu. Selecting Apple TV on AirPlay works until the HA BT signal is stronger then AirPlay is conflicted and uses the strongest HA signal not the AirPLay TV BT signal. The result loss of my AirPlay program which is awful if you're trying,to watch a live event.
your idea to turn off BT on my iPad is great but in my case leaves my HA volume level at its last level. This is normally not a good volume level when for example watching Netflix on AirPlay. finding a satisfactory volume level for me and my non hearing impaired parrner requires twiddling volume levels
