DELL 7567 Audio Stutter

Hello, I have a problem with my 2 months old dell 7567 laptop.

The audio (and sometimes video) stutter when I play music via youtube or Spotify together with other programs (MS Word, Adobe Reader, Chrome, etc.). This problem appears randomly and has no same pattern whenever it appears.

I have the latest drivers from Dell and I have tried the solutions from these links:

And it didn't work.

specs: windows 10 creators update, i7 cpu, 8gb ram, gtx 1050Ti,1tb hdd, 128gb SSD

ps: I upgraded the default 500gb hdd to 1 TB hdd

Thanks
