Hello Dell
Recently, my laptop's motherboard had issues, and i sent it back home for replacements (i was in Nepal at that time, around a month ago).
Now i've returned home, only to find out that the although laptop was good and running, there were no drivers installed at all. The display was huge VGA-type and there was no sound as well. So when i had to download all the new stuff, i decided to upgrade the OS. I installed the Windows 8 Pro from USB.
Everything was good till i noticed that the subwoofer doesn't work anymore. There is no bass, and i cant hear anything coming out of it, even after installing all the sound drivers and Waves MaxxAudio apps. On software level everything works fine and MaxxAudio or Dell IDT control panel doesnt even show any errors.
A friend told me it might be hardware malfunction caused during the replacement procedure.
Please help me if i can fix it by myself or do i have to call for support.
