Yes this is definitely Pulseaudio server problem, i tested it and FLash crashing stopped example with Youtube videos. LGB [Gábor Lénárt] information is correct and i found nasty solution.
I removed all Pulseaudio packages by using Synaptic, use search and find pulse, only packages what i left there are these: libao2 libgsm1 libpulse0 vlc vlc-nox so remove all other and do reboot. But now there is still bug in PulseAudio server what need to be fixed.
