I have the same problem as most in here. Siri/dictation not working, no sound on video from forward camera, voice control when Siri is off works. Facetime has sound on both mics, both front and main camera.

First noticed problems: awhile after updating to iOS8. First problem noticed was lacking sound in a front facing video 2015-01-23. Started researching when attempting to start using Siri more, and was not able to get it to work. Noticed dictation also gone.
Uncertain when Siri and dictation stopped working.
Description:
Problems:
Siri have no connection to microphone, flat line, cannot hear me.
Voice dictation same problem, flat line, no connection to microphone.
Video with front facing camera: no sound!
No problems:
Video with main camera: Microphone works.
Telephone: Mic works
Telephone on speaker: Mic works.
Facetime: Mic works in both directions.
Shutting down Siri: Voice controls works perfectly (can connect to mic, commands recognized). Still no sound on video with front camera.
Read and tried every single solution above in this thread: (āsiri not working after ios 8 updateā on discussions.apple.com:)
All 9 pages, from Sep 18 2014 to feb 15 2015.
Me and 124 others have clicked this subject, but the thread has 109259 views, so it is very likely that this is a larger problem.
Attempted solutions, no success so far:
Shut down all apps in background
Turn off and on again
Disable voice cancellation
Reset all settings
Disable and enable wifi
Disable and enable bluetooth (never used bluetooth earpiece/speaker, only keyboards)
Soft reset with home+power
Update to iOS 8.1.3
Turn off Siri, voice control works! No dictation though.
Turn on Siri: No sound input, still flatline.
Checked microphone for dust/debris (which should be rubbish, if blocked voice control would not work)
Solutions not attempted:
Reset as new device ā Since this has worked for ca no one in thread above.
Swype and swiftkey is installed, both could hypothetically have broken Siri. None was available as keyboards after āreset all settingsā. Tried Siri on my iPad with 8.1.2, Works. Swype&Swiftkey not installed as keyboards yet. Tried installing Swype, Siri mic still works. Not probable cause.
Phone purchased online at launch from Norwegian operator Netcom 2013.10.25
Fortunately, in Norway we have 2 years warranty by law, so I contacted my operator, (known for excellent customer service).
Will attempt full delete to have it ruled out, then contact Netcom store tomorrow for repair/replacement.
Unfortunately we have no apple store/genius bar in Norway, and since apples warranty is only 1 year, it is probably no use reporting it to apple.com. Posting here for reference though.
For me it seems the mic is a hardware issue on my 5s, unless Siri gets back online after full reset. (will keep you posted on that.)
