Public bug reported:
Following on bugzilla #1648448. There's a constant background
"hum/whitenoise" in the headset. The tone and level change whenever
something changes on the LCD screen (window resize, GNOME expose,
click/drag a window around the screen). Muting the headset using Fn+F1
makes the "hum/whitenoise" go away. Unmuting the headset brings the
noise back.
