Public bug reported:
When I begin playback in Chrome while using Pulseaudio, I get only
cracking noises in my headphones, no original audio. Playback works
correctly with e.g. aplay, mplayer, Firefox's plugin-container for
Flash.
If I unplug and replug the device several times, it will start working.
If I disable Pulseaudio and use the ALSA hardware device directly (set
the default in ~/.asoundrc; stop pulseaudio from starting; restart
Chrome) then I do not experience this bug.
