I updated the software recently and I got a problem with chromium playing back HTML5 video too fast. And all of the sound is chopped up and unrecognisable.
Chromium version: 55.0.2883.75-1~deb8u1
Pulseaudio version: 5.0-13
Sound works on other applications, though my master volume control (KDE) is not acting linearly. The volume decreases far too much when I reduce the volume.
In the volume manager it shows Chromium as "ALSA Plugin [chromium] ALSA Playback". After that text it continuously flashes "on" as though it's turning on and off all of the time.
I saw this in the logs which might help:

Dec 12 23:37:42 matts-pc pulseaudio: [alsa-sink-USB Audio] alsa-sink.c: Most likely this is a bug in the ALSA driver 'snd_usb_audio'. Please report this issue to the ALSA developers.
