My Acer Aspire 5732Z Windows 7 laptop is only 5 months old and was absolutely fine up recording sound and video and playing through the speakers until yesterday when I tried to use the Acer Crystal Eye Webcam and it came up with the message "Camera no found!". I then tried to play some music and when I hovered over the speaker symbol on the taskbar (which has a red circle with a white cross on it) it said "No Audio Output Device is installed". I clicked on it and reinstalled the driver device, to which I clicked "Apply this fix" and it replied "Problems found - Realtek High Definition Audio has a driver problem - Not fixed". I then checked whether I could record sounds or not through the Sound Recorder and it said "An audio recording device cannot be found." I clicked on "OK" which then took me to the Sound window, where under both the Playback and Recording tabs, it said "No audio devices are installed." I am very confused as I have never before had any trouble recording or playing sound or video from the webcam so please help!!
