Sounds problems with openSUSE 11.2 64-bit_KDE 4.3.1

Problem

There is flash video playback without sound when running flash videos from sites like youtube. Despite of this you can hear the sound in other multimedia applications like Amarok or Kaffeine.

Comments and approach to the problem

Videos can be watched but not heard. Occasionally we may be tempted to give complex solutions like reinstalling some utility program or deinstalling Flash Player plug-ins, installing another application like Gnash or swfdec flash players. Reinstalling Java and its plug-ins. Deinstalling Pulse Audio drivers and installing ALSA stack. Truth should be told that simple solutions are always better and less painful than other.

Solution

The KDE Desktop 4.3.1 has a small icon standing by an application called Kmix associated with the volume control on the task bar or system tray that shows it as an horn or speaker. If not available there, just look in Home / Applications / Multimedia / Kmix (volume control or audio mixer) and make a left click pointer on the Kmix application to launch it. If Kmix were available in the system tray make a right-click with your mouse or pointer on the speaker icon. This will show you the options Kmix (Mute, Select the Master Channel, Shows Mixer Window). Now make a Left click with the pointer on and it will show the Mixer window. This will show a window with sliders buttons that range from Master, PCM, CD, headphones). Here you will notice that the PCM slider has moved down or at the minimum. Slide the slider up, along with the others accompanying it. Finally, move the pointer to the X to close it over the dialog window so the speaker icon and the application Kmix will be available in the system tray.
