I have a user who is having a strange problem in which his sound works on his Windows Vista machine in every application except for his web browsers.
In Vista, when you have an open applicaiton that is playing audio, there is usually a seperate volume slider for the application, but when sound should be playing through his web browser (both IE 8 and Firefox 3), there is no volume slider in the Mixer.
We have tried uninstalling Flash for firefox and ie, uninstalling firefox, reinstalling firefox and both flash plugins to no avail.
Per a suggestion here: http://en.kioskea.net/forum/affich-22335-no-sound-on-internet
We tried importing the suggested registry values, which I believe is the driver mapping, and still no go.
Made the following reg change as well per the above link:
double click on 'Auto Insert" on the right side of the box.
Change the Value from "1" to "0" and click OK. "
He tried to do a system restore but could not because it said some files were missing.
Has anyone experienced this problem? Thanks so much for your time!
