RE: Dell Inspiron 15 7559 freeze in audio every 20 minutes
How long have you had this October 2015 laptop? How long have you had this issue?
Where did you make that 1 to 0 change?
Do a quick audio test...
* Turn the laptop off
* Plug the laptop directly into your network router via the rightside network port and RJ45 cable
* Turn the laptop on
* The WiFi should have automatically turned off
* Start the movie and test
