snd_hda stutter

[J.R. Oldroyd]

I am using snd_hda on a Toshiba Satellite L105, FreeBSD 7-stable.
The verbose info is here:

The audio suffers from periodic "stutters", about 1 to 3 seconds
in duration, occurring every minute or two, which as you might
imagine is rather annoying.  Doesn't seem to matter what the audio
source is: mplayer, vlc, xfmedia or a web-based stream.  The effect
can be described something like this:

    "Where ever you are, you're wi-i-i-i-i-th the BBC in London".

After it recovers, it will play fine again until the next glitch.

Is this easily fixed?
