I've read a lot about popping and crackling... This is NOT that issue.
I've noticed lately that if I am typing while listening to music that certain key presses (usually the top qwerty row) the speaker sound becomes 'muffled' or 'foggy' sounding temporarily - as if pressing down in the area close to the speaker causes it to happen.
Can anyone advise? Obviously a hardware issue, but I'd appreciate any feedback from any similar situations users might have had?
I found some information that may help you resolve the issue. Also, update your system bios as well as any new audio drivers; if available .
VLC Player should not be used to increase the volume. This will result in crackling of the sound. VLC tweaks and amplifies the sound by increasing the +dB (decibel). VLC player in long run will affect the speakers. If VLC player is used, please refrain from increasing the volume beyond 90%. Run the diagnostics on the Audio by starting the computer and pressing the F12 Key and choose Diagnostics from the menu.
