Bug#756150: pulseaudio: High pitched whine through headphones when no audio is playing

[Harlan Lieberman-Berg]

Package: pulseaudio
Version: 5.0-2
Severity: normal

Dear Maintainer,

I've recently noticed a high-pitched whine playing through the headphones,
specifically when no audio is playing - or, perhaps, when nothing is accessing
pulseaudio.  Having any sound application open but playing no sound (mplayer
paused, for example, or flash running with the sound muted) silences this
whine.  Additionally, having the Gnome sound control panel open to see what
applications are accessing pulseaudio also prevents the sound from occuring.

If any sound is player, the sound will instantly vanish, only to return within
about ten seconds of the next time no audio is playing.

I have the following sound modules loaded:

snd_hda_codec_hdmi     40955  1
snd_hda_codec_via      22798  1
snd_hda_codec_generic    59065  1 snd_hda_codec_via
snd_hda_intel          43768  12
snd_hda_codec         100159  4

snd_hwdep              13148  1 snd_hda_codec
snd_pcm                84566  4 snd_hda_codec_hdmi,snd_hda_codec,snd_hda_intel
snd_timer              26614  1 snd_pcm

soundcore              13026  1 snd

My sound hardware is:

00:03.0 Audio device: Intel Corporation Crystal Well HD Audio Controller (rev
08)
00:1b.0 Audio device: Intel Corporation 8 Series/C220 Series Chipset High
Definition Audio Controller (rev 04)
