I've recently had to format my G73JW-A1 this past weekend, once I got everything back up and running I noticed my sound was off and from what it sounds like my sub-woofer is not working. My sound is noticeably flat and was never like that prior to formatting my hard drive. I have the most recent drivers installed and still no fix, also under the Realtek HD audio manager I'm unable to select configuration (it's grayed out). Im currently running the Realtek 2.63 drivers. I was wondering if anyone has came across this issue and if so is there a possible fix. If there is any other information you need please let me know.
