I am unable to hear sound through my phone speaker now inc Voiceover. I've recently upgraded to IOS9.1.
I think it may have something to do with the bluetooth headset or some IOS software glitch as earlier in the day, I recieved some calls and was unable to anser them via my bluetooth and then the phone app seemed to crash when I tried to end a call.
At first, I could only hear sound through wired headphones and no sound through either speaker or bluetooth but I've managed to get sound through my bluetooth again.
I can get some sound to play through my speaker for 2 seconds if I go to settings -> sounds and increase the volume. It plays the ringtone and voiceover speaks through my speaker for about 2 seconds before stopping.
I've restarted Voiceover and rebooted my phone several times including pressing and holding the home button and power buttons at the same time.
Any advice would be appreciated
