Sound

After updating from openSUSE 11.1 to version 11.2 and the incorporated transition from KDE 3.5 to 4.3 on one PC the sound generated by KDE applications (including system notifications) only worked every once in a while: when logging in it was there or it was not until the end of the session, where this behaviour appeared to be arbitrary and non-reproducible. At the same time, non-KDE programs did not show such bugs, their sound happened to perform faultless.
