Sound choppy with Win 10 host, Ubuntu guest

[FreyjasChosen]

Hello all,
I'm new to virtualization. I just installed Ubuntu in VirtualBox on my Windows 10 desktop PC in order to study for Linux certifications. Everything seems to be working find except for the sound. When I load up Pandora Radio or Youtube videos, the sound is skipping ahead around 2-3 seconds each time, and it sounds like a garbled mess. The settings are:

Host Driver: Windows DirectSound
Controller: ICH AC97

I tried using Intel HD Audio and SoundBlaster 16, neither produce any sound. They're silent.

Any advice would be appreciated. Keep in mind I'm a total beginner to this, so talk to me like I'm 5. Thanks!

EDIT: I have a Core i7-6700k and am using on-board audio.

Any advice would be appreciated.

My advice would be to use... search engines. If you don't find any references, let me know...

BTW, a great tip for search engines is to limit the scope of the search, e.g. "sound choppy site:forums.virtualbox.org".
