When I plug in my TV's HDMI cable into my laptop (Acer Aspire R3 131T, Intel
Audio) i get a really annoying, high frequent whine from the TV speakers.

It doesn't matter how loud the volume is set, the whistle is always the same
until I playback some music or video or something else via HDMI, even if the
music is super silent - the noise disappears as long as the music lasts.
After hitting the pause button, the debug log looks something like that:

--------------------------
D: [alsa-sink-HDMI 0] alsa-sink.c: Cutting sleep time for the initial
iterations by half.
D: [pulseaudio] module-udev-detect.c: /dev/snd/controlC0 is accessible: yes

The funny thing is, if I run a "speaker test" (HDMI) on gnomes audio settings,
then the noise doesn't appear again (until i pause another video/music again),
the debug log looks like that when the noise is gone:

--------------------------
D: [alsa-sink-HDMI 0] alsa-sink.c: after: 1632
D: [alsa-sink-HDMI 0] alsa-sink.c: Rewound 6528 bytes.

It also doesn't happen on the _internal_ speakers of my laptop, after hitting
pause on VLC, the debug looks like that:

--------------------------
