After updating to 9.0.1 Siri stopped working

[el_duderino]

Also the the videos from the front camera only have sough. The voice recording and phoning works. the update to 9.0.2 didn't solve the problems. is this a hardware problem or a software problem?
How can i downgrade to 8.4.1?

I´m on 9.1 beta 4 and have the same problem.(iPhone 6 plus) No Siri as well as no dictation for example in messages or mail.
When using my headphones siri and dictation works just fine....

imo this must be a software problem, because the voice recording works with the same mic as siri and dictation
