First ~500ms of audio gets dropped

[Sam Varshavchik <mrsam@xxxxxxxxxxxxxxx>]

One of my laptops has a minor, but an annoying, glitch with audio playback.  
I've observed this behavior with both Firefox and other audio playback  
applications. When audio playback starts /for the first time/, maybe the  
first 400-500ms of audio gets dropped, and then the rest of the audio plays  
fine.

What's interesting is that pausing the audio for a few seconds and resuming  
it does not result in dropped audio. But if the audio playback gets paused  
for a longer period of time, resuming it once again drops the initial 400-500  
milliseconds of audio.

This happens only on one of my laptops. All of them are based on the XFCE  
spin, and generally have the same set of packages. This must be hardware  
related. This is my hardware (lspci -v):

00:03.0 Audio device: Intel Corporation Xeon E3-1200 v3/4th Gen Core  
Processor HD Audio Controller (rev 06)
       Subsystem: CLEVO/KAPOK Computer Device 6504
       Flags: bus master, fast devsel, latency 0, IRQ 35
       Memory at f7e14000 (64-bit, non-prefetchable) [size=16K]
       Capabilities: <access denied>
       Kernel driver in use: snd_hda_intel
       Kernel modules: snd_hda_intel


I'd be curious to compare notes with anyone else that has the same audio  
hardware.

The most annoying part of this is that this manages to perfectly drop the  
"new mail" notification from one of my Firefox extensions. By the time the  
audio hardware decides to do its job, the horse already left the barn.
