i posted this in CSSU thread - probably wasn't the right place:

I have an issue in last few days when listening to music through someplayer and symphonie. The music suddenly loses sync during playback and becomes fast - this happens from time to time.
I checked the packages which were updated in the last two weeks and noticed that the following were also updated (old version -> updated version):

libpulse-mainloop-glib0 0.9.15-1maemo44+0m5+0cssu6 -> 0.9.15-1maemo44+0m5+0cssu6+thumb0
libpulse0 0.9.15-1maemo44+0m5+0cssu6 -> 0.9.15-1maemo44+0m5+0cssu6+thumb0
pulseaudio 0.9.15-1maemo44+0m5+0cssu6 -> 0.9.15-1maemo44+0m5+0cssu6+thumb0
pulseaudio-esound-compat 0.9.15-1maemo44+0m5+0cssu6 -> 0.9.15-1maemo44+0m5+0cssu6+thumb0
pulseaudio-module-bluetooth 0.9.15-1maemo44+0m5+0cssu6 -> 0.9.15-1maemo44+0m5+0cssu6+thumb0
pulseaudio-module-gconf 0.9.15-1maemo44+0m5+0cssu6 -> 0.9.15-1maemo44+0m5+0cssu6+thumb0
pulseaudio-module-hal 0.9.15-1maemo44+0m5+0cssu6 -> 0.9.15-1maemo44+0m5+0cssu6+thumb0

if this might be the cause - which one should I revert back to try and solve this issue?
