[Fix/Solution] Inspiron 15 7000 series - Audio/Sound issue
I've been having this crackling/static noise for some time now on my Inspiron 15 7577 laptop. The static / crackling / popping / cracking / flickering sound was coming out of my speakers and my headphones (when I plug them into the headphone jack). Strangely enough, it doesn't happen when I use a USB-wired headset. It must be due to my headset's driver.
(I'm purposely leaving that as "static / crackling / popping / cracking / flickering" so I can catch as many hits as possible when this issue is searched on the forums or on Google)
So anyway, I found a solution: Lower the sample rate and bit depth quality.
Right-click the Sound Icon on the bottom right corner.
Click on "Advanced" and set your bit quality to "16bit 48000".
I originally found mine at the max level of quality... I think I did that myself at some point. Or maybe Dell sets that as the default when it gets an update or something. I think the laptop's driver isn't powerful enough to handle the higher sample rates and bit depths. Experiment to see which level works for your laptop.
