Well, my model is SVE15114FXS running windows 7 home premium. I can only use the webcam for the first time I use video call of Skype or Yahoo messenger. Arcsoft shows up at that time. Then, I stop the video call and then do video call again. The webcam is
hung. Exactly, the light next to the webcam still on, but it said there is no webcam plugged in.
If I want to make webcam work again, I have to shutdown (not restart) and turn on my laptop again.
One time I did something with my software and the webcam did not come back by above trick. I need to open Vaio Care > Advanced Tools > Restore and Recovery > Reinstall applications and drivers. I ticked all the drivers and Webcam companion, Magic visual
effects and reinstalled them.
Waited a bit, restarted my laptop and the webcam re-appears.
So far, my solution to work well with webcam in skype or yahoo is using virtual machine. I installed VMware player, and made an virtual version of XPSP3. Inside the virtual machine, Skype works just fine with the webcam.
If you got problem to connect your webcam into virtual machine in VMware, restart your computer, plug in an usb drive, connect this drive to virtual machine first and then the webcam. I don't know why but that's the only way I discovered to connect my webcam.
Remember to unplug your webcam and usb drive out of your virtual machine when you've done your job. If you always plug in the usb drive in your real machine, you don't have to do this step.
