    New USB webcam - mic not working, not found

    I recently bought a Logitech C270 HD webcam, brand new. I cannot get its built-in mic to work. Video works fine but no mic is detected. I’ve made sure it’s enabled in Device Manager. And under PC Settings>Privacy>Microphone, ‘Let applications use my microphone’ is set to On. I’ve installed the relevant drivers several times with no luck (had to do it from a 3rd party site as the Logitech support site isn’t working properly). Zoom and Skype can’t detect the mic. Neither can Sounds or Sound Recorder in Windows (running 8.1). When I run Troubleshooter, Windows says the mic is Disabled (which I can see it isn’t).

    I tried updating the onboard Realtek audio drivers from HP (my PC is a HP Pavilion 500-515) in case there was some sort of conflict, but that made the speakers stop working, with the same problem as the mic - Windows said they were disabled, which they weren’t. Is there a setting hidden away in Windows that’s disabling new audio devices? Any help appreciated.

    Hello

    It is a possibility that that mic,might be defective.. Did the cam come with software? Also as soon as possible i would replace that third party driver.. These are known to have a lot of useless ad’s/software in them as soon as Logitech site is working properly.. It may come down on using the warranty and get a replacement..

      It didn’t come with any software. The drivers & software I used are the Logitech ones, but from a different site as the Logitech site is unusable. Initially I thought the mic might be defective, but then after trying to update the sound card drivers I had the exact same problem with the speakers as I’ve got with the webcam mic - they were not recognised, and windows thought they were disabled, even though they weren’t. I sorted that by doing a System Restore and the speakers work fine, as they had done before. So I think it’s some sort of problem within windows when trying to update the audio drivers/software

        Ok and it also could have been that 3rd party site you went to for those drivers causing your issues before you rolled back..

          Fixed. For anyone with a similar problem, I found the solution here:
          When running the troubleshooter for the Audio it gives me the error "Audio device is disabled" followed by not fixed with a red x.  When going into the Control Panel in classic view under Sound it has my device enabled but I can not make any…


          This is what worked:

          Go to Start>Search and type ‘cmd’. Search will return cmd.exe. Right click on this and select ‘Run as Administrator’. At the prompt type:

          net localgroup Administrators /add networkservice
          press enter then type:
          net localgroup Administrators /add localservice
          press enter then type:
          exit
          press enter and restart your computer

          Thanks for the replies, vger
