A lot of people seem to be experiencing issues with ALSA apps (like Flash) on PulseAudio-enabled systems. Common issues include programs locking/"hogging" the ALSA sound device (prevents other apps from mixing and using the audio device) and also apps trying to use the ALSA software mixer (dmix).

Here is a method to route ALSA apps directly through pulse:

gksu gedit /etc/asound.conf

Copy/paste these lines into the resulting file:

pcm.pulse { type pulse }
ctl.pulse { type pulse }
pcm.!default { type pulse }
ctl.!default { type pulse }

Save. Quit. Reboot.

    And remember kids, if your sound drops out completely, this command is your friend:

    sudo alsa force-reload
