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!!

Check Problem Devices report

• Make sure all your devices are connected and powered on
• Click Start->Run, enter: msinfo32. Click the + sign next to Components to expand it
• Click Problem Devices. Anything appear?
• If yes, click on it, Ctrl-A to select all, Ctrl-C to copy it, Ctrl-V to paste into next post

Generate and attach a DirectX report

• click Start->Run, enter dxdiag
• Notice progress in lower left window corner
• When done, click Save Information button and save to your Desktop
• In TechSpot, use the paper clip icon to attach the report. (If you don't see icon you may need to first click Go Advanced)

Thank you for your reply!! I did the Run thing and it says:

I've also attached the dxdiag. Thanks

for starters i would suggest you try to reinstall the software for both webcam and sound.

to install drivers from your acer notebook, try to download the respective drivers:
sound
http://global-download.acer.com/GDF...ep3=Aspire 5732Z&OS=721&LC=en&BC=Acer&SC=PA_7

webcam, either one of these:
http://global-download.acer.com/GDF...ep3=Aspire 5732Z&OS=721&LC=en&BC=Acer&SC=PA_7
http://global-download.acer.com/GDF...ep3=Aspire 5732Z&OS=721&LC=en&BC=Acer&SC=PA_7

P.S. in acer crystal eye, when it says "camera not found" it can also means that the webcam is used by another application.

Good tip nismo!

I was expecting to see the cam listed among the "problem devices" but it wasn't... But when i read your post, is one reason that could explain why it's not there.

And good to reinstall the drivers next step as well

/* edit */
Oh. just thinking.. there's also another maybe not so good explanation about the cam..

After reinstalling the drivers, if cam still a problem, also open device manager and look to see for the cam to see if appears in Dev Mgr (it'll probably be listed as an Imaging device or maybe under USB). Also check if there's an Other category in DevMgr and if so, if anything is listed under it

just a few hours back i reformatted my acer notebook (it's a 5930) and have some issue with the fingerprint sensor. a driver reinstall and system restart solves it though. i'd figure out he/she might want to try it...

and you're right, the acer HD crystal eye webcam should appears in the imaging devices section.
