Ipad Air 2 , no sound internal Speaker when Play iTunes/ youTube , but plug in HEADPHONE = sound is Hear (ok)
that mean AUDIO circuit is OK, but software problem. checking below.
in YouTube video --> AIRPLAY = headphone only ( no other OPTION)
the correct must be AIRPLAY = " speaker Ipad"
for now it is a BUG , APPLE will Fix it later.
to FIX this problem , must do " RESTORE IPAD"
connect ipad to Macbook (usb) Then Open Itunes
1- do " Back up" ( 1 minutes if you did backup before)
2- do " Restore" ( 3 minutes only)
this will set IPAD air 2 back to "ORIGINAL MFG DEFAULT"
***** Congratulation= fix , AUDIO for internal speaker is working *******
now play youtube= airplay= speaker iPad , & play itunes = ok
Note: it is very nice . if you have set up cloud & same apple ID , everything will restore back include , all APP, iTunes SONG/ video
you do not need to reinstall APP , or SONG in iTunes etc...
APPLE made this is perfect . SAVE lot time
