Bug#867548: playback to HDMI monitor stutters / pauses

[Daniel Pocock]

Package: pulseaudio
Version: 10.0-1
Severity: important

When playing audio through the HDMI monitor, I've noticed it
stutters/pauses every few seconds, very briefly, less than a second each
time.  It is very irritating to listen to.

In the middle of playback, I can open the GNOME settings panel for sound
and switch the output to another device (e.g. my USB sound card
connected to an amp with an optical cable) and it works fine.  As soon
as I switch back to the HDMI output the problem comes back.
