So I bought my brand new laptop a month ago (Dell Inspiron 15 7000), and since I got it I noticed two things that nagged me big time, first a skip or pop in the sound every so many minutes ( it could be in range of time between 10 to 30 minutes), it could be while listening to Youtube, Spotify or Netflix. Sometimes I can be very obsessive over some things that many people just could overlook but since I spend a month salary in this laptop it kind of annoyed me that it wasn't workings as expected, since it was a little pricey for me. Also every time I plug or unplugged the charger the audio made a buzzing sound that really used to get under my skin. After I reviewed some blogs and youtube videos I got a tip on disabling the a system device: DELL DIAG CONTROL DEVICE. After doing it, the problem was solved, no more skipping/popping in the audio so far, and the buzzing sound after pluggin/unplugging the charger was gone.
My inquiries are : what does the DELL DIAG CONTROL DEVICE is meant for? why disabled it fixed my problem (if what I commented can be take as a problem)? and what could be the downsides of operating my laptop without it?
Thank you in advance for reading my long post, hope to hear some answers.
