I was having sound problems with my Aspire V3 (571G). I was hearing some popping noise while listening to music and watching videos. It was really annoying. I thought it was a problem with the Dolby Home Theatre v4, so I went to control panel>uninstall a program>dolby home theatre>Repair. It didn't solve the problem, so I went to C:\ and copied the folder "Dolby PCEE4", then I uninstalled Dolby Home Theatre v4 thinking that I'll reinstall it by putting the folder back to it's directory. While it was uninstalling I found out that the problem wasn't the Dolby home theatre, instead it was some sort of audio enhancement, so I disabled it by going to Audio>manage audio devices>speakers>properties>enhancements and I checked the box: "disable all sound effects". The sound is fine, it doesn't do that popping noise but now I can't reinstall Dolby Home Theatre v4. I put the folder "Dolby PCEE4" back to C:\ directory and it didn't work. I opened the folder and I found a command called "install" so I executed the command, but it only created 15000+ files (3.79 GB) in the folder and Dolby home theatre was still not installed. So I went to http://us.acer.com/ac/en/US/content/drivers and I entered my model name and OS (Windows 8), but there wasn't a "Dolby home theatre" application or driver available for download. How can I reinstall Dolby Home Theatre v4?
