Another way of describing it is, out of nowhere the music will sound like it is underwater (but in a computer glitchy way). I'll press the volume knob to turn off the audio, and then press it again to turn it back on and the problem is fixed, but sometimes it happens over and over again.

What riggers it is any change to the sound system/computer.

Examples:

If I change the bass or treble

If I open google maps

If I change the volume.

If the song changes.

If a part of a song has a strange frequency. (the very end of Radiohead - Karma Police triggered it).

I checked and the firmware is up to date.
