Hi 1tracy,
welcome to club VAIO..
Have you tried a system restore to a point when you had sound.?
HERE is a guide should you need it.. 
hi. Thanks for the welcome.
Ya I tried to restore to another point,that didnt work , ran a diagnostic through and that didnt work.
Then in total frustration restored the whole computer. Back to the begining.................still no sound.
Everything looks like it is working but no sound. The only thing I can think of is that the computer was getting very hot and maybe It caused some damage to the actual speeker. ???????

To boot into safe mode start your vaio and when you see the Vaio logo press the F8 key repeatedly..
