Bug#848029: chromium: v55 security upgrade broke Pulseaudio support on jessie

[Plamen Tonev]

I'm having exactly the same issue. With v53 I cannot open some HTTPS 
sites (Amazon for example). This certificate transparency issue was 
fixed in v55 but now with this new update all audio/video sites 
(Youtube, Google Music, Vimeo) are not playing properly.
