Luke,

I tried what you suggested and still not working correctly.  If I start the flash first, then sound works, but it gets hold of the sound card and no app that uses pulseaudio works.  If I start app which uses pulseaudio first, then flash does not work.  I am on 64-bit version.

> Status in PulseAudio sound server: Confirmed

> Status in “alsa-plugins” source package in Ubuntu: Fix Released

> Bug description:
> Steps to reproduce:
> 
> Run both of these at the same time:
> gst-launch-0.10 audiotestsrc ! pulsesink
> gst-launch-0.10 audiotestsrc ! alsasink
> 
> If your default sound device does not support hardware mixing, the second command will fail. ALSA cannot use the device while PulseAudio is using it, and this affects a lot of applications.
> 
> Note that if you run the commands the other way around, alsalib will use dmix, and then so will pulseaudio, so there is not as much of a problem this way around (except for the fact that dmix and PA are doing the same job, and you can not control the ALSA-using apps' volumes and routing with PA.)

> 
> Resolution:
> 
> Follow http://pulseaudio.org/wiki/PerfectSetup#ALSAApplications
> i.e. install /etc/asound.conf with:
> 
> pcm.pulse {
>     type pulse
> }
> ctl.pulse {
>     type pulse
> }
> pcm.!default {
>     type pulse
> }
> ctl.!default {
>     type pulse
> }
> 
> Then, install the package "libasound2-plugins", as it contains the required "pcm_pulse" and "ctl_pulse" plugins.
> 
> Note, too, that there are some applications that fail with ALSA->Pulse:
> 
> SDL* seems to hang with neverball, but that is fixed by installing the PulseAudio backend for SDL (libsdl1.2debian-pulseaudio), which will replace the default ALSA backend.
> WINE has its own issues with regards to device selection, which I don't know a remedy for.
> Skype* also has its own problems, but these aren't fixable by us and should not block us, though should be given some consideraton.
> 
> * SDL applications (using libsdl1.2-alsa backend), Skype and possibly other misbehaving applications work properly with later versions of libasound2 & libasound2-plugins from Debian unstable.
