Audio Glitching on YouTube/Flash

Sorry I can only offer a generic help with searching for solutions which is half the battle, particularly when it may be specific hardware related.

  1. Get audio info on a terminal with:

inxi -A

  1. Grab (copy) the full name of the audio device. Here's my output:

    Audio: Card-1 Intel 8 Series/C220 Series High Definition Audio Controller
    driver: snd_hda_intel
    Card-2 NVIDIA GK208 HDMI/DP Audio Controller driver: snd_hda_intel
    Sound: Advanced Linux Sound Architecture v: k4.4.0-36-generic

  2. Now, paste that (usually) Card-1 full name into a search. Put it in quotes to narrow it right down to your hardware. Mine would be:

"Intel 8 Series/C220 Series High Definition Audio Controller"

Add Ubuntu Mate 16.04 (or whatever may help) to the search. This approach has worked well for me.
