Chrome and flash with stuttering sound

Hi,

same problem here. 
Configured Pulseaudio with simultaneous output on HDMI (nvidia) and HDA Intel
(Realtek codec) analog stereo.
Attached log file from test with Chromium and flash running a video stream from
the internet.
With pavucontrol openend and restarting chrome the stuttering vanishes.

Without simultaneous output and testing each output seperatly, everything works
smooth.

I have also tried pulseaudio-2.1-r1 with realtime USE-flag and pulseaudio-3.0
with same result...sound is still stuttering under high load.

regards,
Kontr-Olli

latest Gentoo system.
