No audio in FaceTime?

Friend with a new iMac called me on iChat today about a problem he was having. We audio chatted, shared screens, etc., and had no problems communicating. Tonight, he called via Facetime. Picture both ways was fine, but while I could hear him, he couldn't hear me.


I have an iMac 27" quad i7 running 10.7.1. Sound prefs on my end shows that the internal mic is registering sound, and I was able to record my voice in Garageband.


Is there any reason why audio would work fine in iChat but not in FaceTime?


Thanks!

OK so I had the same issue as the OP. Mic was working in all other apps and even worked fine in Audio only calls in FaceTime. The issue turned out to be a miss match of operating frequency from the Audio Device to what the application is expecting.


SOLUTION:

Go to Utilities and open Audio MIDI Setup.

Go to Window and select Show Audio Devices

Select Built in Microphone and make sure the format is set to 48000.0Hz 2ch-24bit Integer.


Mine was previously set to 44000.0Hz and the application is expecting a 48000.0Hz input. :-) Now the microphone works perfectly and all parties can hear the audio signal.


Hope this helps others.

Hi,


Depends on Mic chosen in Face Time (Video Menu)

May depend on th volume set for that device when it shows in System Preferences > Sound > Input.

Hello!


Nope, Mic settings in both FaceTime and System Prefs were the first things I checked. All copecetic. Strange thing is, after the FaceTime failure, my friend and I switched back to iChat and were able to old both video and audio chats without problem. Something is funky with FaceTime. Will try deleting the FaceTime prefs....


Thanks for replying!

I also have the same problem. No outgoing audio with FaceTime. I'm using the internal mic, in the system preferences sound menu the internal mic level meter is showing that the mic is working. Skype works, iChat works, but in FaceTime the person with whoom I communicate (on his Mac or his iPhone) can not hear me. I have an iMac (20", end of 2006) and I'm using OS X Lion 10.7.2.

Hi,


Is the Mic selected in the video menu ?

(It is not selected in Preferences like iChat is)

Hi,


IN that case use the Finder > Go Menu > Go to Folder and Enter ~/Library/Preferences in the dialogue box that appears.

Find the com.apple.facetime.plist and any associated .lockfile and drag them to the Trash.

Restart Face Time
