Q: Does the iSight external camera work with El Capitan? Upgraded this week and have no audio with FaceTime.

I also just discovered that my MacPro (Early 2008) is detecting the audio of my iSight camera either.  You will see in your Sound Preference that is doesn't even see the iSight as a input device, which OS should see it as one.

This is a big bummer for me as the iSight had allowed me to use the FaceTime and Dictation features in previous OS versions.

Yes.  I turned on old iSight (open shutter), connected to Firewire, then lanuched FT and configured camera and mic settings.

In addition to FaceTime, I also tried the old iSight with my El Cap Mac using both QuickTime video recording and iMovie.  All work fine.

If you still have problems, check to be sure your old Firewire iSight still works. 

If your trouble persists, you might want to  use OS X Recovery to completely reinstall your Mac OS.

I have fixed mine by unplugging the iSight and plugging it back into the computer in a different port (likely not relevant).  The iSight appeared in Sound Preference at this point and then I returned the camera to its original port.

It is funny that rebooting didn't have an affect.

I followed the previous suggestions and did not find them helpful. But this one worked, and simply by unplugging and plugging back into the same port.

I use a 400 Mb/sec iSight camera with a 400/800 firewire adapter. I had the same issue until I (hot) unplugged and replugged. Checked by calling my iPad and now the audio is working fine, even though it previously was video only. The settings were correct for audio and video before. Odd that the video was still fine but there was no audio.

Hello

I recently picked up mint iSight camera.  No issues. No Problems. Runs great on my 2012 mac mini.  I already had a FW 400 to 800 adapter (RocketFish) so that came in handy, since my 2012 has only a FW800 port.  http://www.amazon.com/Rocketfish-Mac-FireWire-Cable-adapter/dp/B005JL2PXA

I plugged the FW400 adapter end directly into the iSight and ran FW800 cable from the bottom end of the adapter the mini's 800 port. 

FYI .....Actually the 800 cable snaked in through the iSight laptop monitor adapter pretty nicely (where the original apple FW 400 cable was originally), and then I plugged the 800 cable into the bottom of the RocketFish, and then plunged in the 400 end of the RocketFish, directly into the iSight.  If that makes sense.

I can confirm that the iSight works under El Capitan, and as a precious poster said......"works in FaceTime, iMovie, and Quicktime". 

My one suggestion with audio, in El Capitan, be sure to go to System Preferences>Sound>the Input Tab, choose iSight (it should be listed there). There is actually a display setting that shows you in real time the volume level of your input from the camera.

Hope this helps someone.
