[Bug 1543724] [NEW] Audio stuttering. Only tried earphones. [HP Pavilion dv6 Notebook PC, IDT 92HD81B1X5, Black Headphone Out, Front] Underruns, dropouts or crackling sound

 

Public bug reported:

Running Ubuntu 15.10.
I'm not sure if the bug is due to the alsa-driver or something else. At times audio stutters and jitters regardless if its being reproduced by media player or browser. I had to reinstall Ubuntu a few weeks ago because of a video driver problem and after that re-installation I started having this problem, but I might as well haven't noticed it at the time. I surely didn't have this problem with Linux Mint 17.3. I hope I didn't miss any useful information. Thank you for your attention and for your dedication.
