Hope someone can help. Have a Logitech 4000 webcam which records video sound but when camming in yahoo cant get any sound. Would love to be able to chat to friends rather than typing.

Have tried switching between USB external microphone and built in microphone - no luck.

Any ideas anyone - thanks.

Most likely this is a driver/application compatibility issue rather than a broken mic. already shows the webcam records sound locally, so the hardware and mic are OK; the usual problem on Mac OS 9.2 is that some QuickCam drivers only present audio to the camera's own capture program and do not register as a system input that other apps (like Yahoo Messenger) can use. was on the right track calling out a limitation.

Practical steps to narrow it down:

  • Close any QuickCam capture app and any other program that might be using the camera or mic. Then open Yahoo Messenger Preferences and look for an Audio/Voice input device list. If the QuickCam mic does not appear, Yahoo cannot see the device at system level.
  • Try recording audio with another system app (QuickTime Movie Recording or any sound recorder available on OS 9). If that app also cannot select the QuickCam as input, the driver is not exposing a system audio device.
  • Check the Extension Manager and USB control panel to confirm the Logitech extension is loaded and the camera is recognized on the USB bus. Reinstall the official Logitech QuickCam drivers for OS 9 if available, then reboot.

Workarounds if the mic never appears as a system device:

  • Use a separate USB or analog microphone that mac OS 9 exposes as a standard input, or run the cam on a machine with Mac OS X or Windows where driver support is better.
  • If upgrading is not an option, do cam video with the QuickCam app and use a separate phone/VoIP audio path for voice.

If the above tests show the QuickCam only works inside its own software, the realistic fixes are driver replacement or using a different input device or platform.

It might be a limitation in the audio hardware.

What system are you running?
