SOLVED: Alienware13R3,15R3,17R4 sound driver .8098 problems

Hi, 

Alienware 13 R3 owner here.

After installing latest .8098 sound driver off DELL support page , I started to have flat sound coming out when playing youtube videos occasionally, as if the Alienware sound center was not processing sound. Reverting to any older driver such as .8536 or older solves this issue.
