Sound is glitchy in music/movies/games

[Tubadroid]

This keeps happening from time to time and then comes back. Resetting the phone, killing apps, doesn't work. The sound still has "pops" in it. Like the software decoding the sound is having errors or something in playback. I'm wondering if this is a hardware issue. Has anyone else had this issue?

Download Android Speaker, it produces a sound wave and vibrates to release dirt that causes cracking and muffled sound caused by dirt.

It's not just the speakers, it does this when their is line out/headphones plugged in too. I first noticed it when music playback sounded glitchy on my car speakers. It essentially sounds like a normal song with random pausings in it aka pops/glitches

Figured out the issue

W/AudioFlinger( 149): RecordThread: buffer overflow

but I don't know what to do about it.

I can't decipher that ... what's the problem (in plain English)?
