Does this camera have a built in mic - or do I need a sperate mic to skype

Check in the skype window itself if the microphone is set to the cameras built in mic. The mic may also have gotten wet or simply ceased to function.

Have you checked your device manager settings? You may need to 'enable' the built in mic if it has one. Skype has a test mic that works to help you hear yourself after this.

Your mic that is build into the camera might not have been selected.
For instance in Skype got to
Skype > Profile > Change Sounds > Audio settings > Mocrophone
Select from the pull down list the Microphone (8-bit USB Device).

you have to select the settings for skype...your camera is working but first you go into tools and settings to turn on the camera also mic(if u have)

Go into Skype Options (Tools menu -> Options).
On the left panel, click on video/sound settings and select your camera from the list on the right.

If you have an earlier OS, you may have to access your hardware from the Control Panel.

If you have a laptop it will have a built-in Mic
If you have a webcam with a built in Mic you now have 2 on your computer and you are going to have to determine which one to use (make it 'default')
I would recommend using the webcam mic as default.
You do not say what your pc or OS is so here is the setup for
Laptop x Vista

Hi, first of all you need to make sure you have the microphone configured properly. If using the cams built in mic you need to make sure it works . If using XP Open the control panel and click the sounds and audio deviecs, click the voice tab, there you can select which Mic to use: the USB cam mic or another mic , then click test hardware. If you should see a mic playback test. if the level is there then the mic is working. next see if there is a mic level test/adjustment within the camera software, if using skype you also need to set it up and turn up the Mic level there too. you may need to add a mic, some USB cam built in mic aren't that good. you can buy a cheap mic and plug it into the pink jack.
hope this helps, please leave a 5 thumbs up if this helped

You need to check if the mic/s is working?
Are you certain the Logitech webcam has a built-in mic?
To check if the mic works go to Start - All programs - Accessories - Entertainment - Sound Recorder and test record your voice and play back to check, also try it with the laptop's built-in mic (if it has one) and the Logitech mic.
If both mics work then you have a choice of which one you can use in Skype, most likely the best one would be the Logitech one.

You need to configure your audio settings in Skype.
When you open Skype click on Tools - Options - Audio Settings and click on Select Microphone and select the microphone you are using and save the setting.

If you still have problems get back to me with all details and error messages.

Did you check the sound settings for the mike?
