did you (or maybe Sony prompted you to) update anything before this loss of sound? if you did, then check out the website below and try to restore the updated components. especially the Sony shared library.
Thank you for the link. However, when selecting my OS, Vista Home Premuimm the following is displayed:
"There are no original drivers currently posted."
I updated my video chat service and later that day I lost sound.
But the service support was of no help, so I uninstalled their program.
That was useless, the problem stayed.
The Sony e-Support web site directed me to a file that would not download correctly, (xyz.exe not a valid windows file) & upon contacting them they said that meant I had a virus.
Ran AVG & came up clean & went back to the site & just guessing, right clicked on the file and used, "Save Target As" & it worked fine. It just didn't resove anything.
I was under the impression that Sony & MS had more of a say as to what drivers my pc would use...aaagghh!...it's hard to explain...I didn't think my video chat software could take over my entire computer!
I guess I'll just call Sony, then post the rest of this awful mess in Company Complaints.
Thank you everyone for your help!
