Why can't I play iTunes music on BOSE speakers through Apple devices?

All of a sudden in the past few days, none, I mean none of my BOSE speakers, systems etc, is compatible with Apple.

I used to able to play music from my iTunes Library straight over my Bose systems without any adjustment what so ever. Now it tells me that " Select a preset, or explore music on the Sound Touch app."

I have explored this option & the different online radio signals I have listened to before this are still broadcasting, however I cannot access my 10,000 song iTunes library.

I have "re-synced" the Bose equipment, deleted the signal, re-entered it, re-synked it, but to no avail not one of my 3 systems responds.

Did Bose & Apple have a falling out ? or, is it a Microsoft created situation?

Help....I miss my music.
