I had an Aspire 3 for a few years now but I recently got an Aspire A515-57G to help editing and making videos.
But I quickly found that the audio quality on the Aspire 5 was worse than that of the Aspire 3.  Sadly, I can't upload a video or mp3 to let you hear the difference in quality of sound as it would be easier to understand where I'm coming from.  The Aspire 3 had a clear sound whereas the Aspire 5 has the dull bass sound to it.
I went to the support page and there was two Realtek audio drivers that I can download.  One that was already installed when I got the laptop and an older version.  So I uninstalled the newer one and installed the older version, but the quality of sound remains this dull bass sound.
Any help would be most appreciated.
