MediaPlayerConnectivity volume can't be adjusted

Problem: while using the MediaPlayerConnectivity add-on (to Firefox) to
watch C-SPAN

  • volume can not be adjusted using any sliders in KMix

  • right click on ‘speaker icon’ in tray and click on ‘mute’ does nothing

  • volume can not be adjusted using any slider in “Volume Control: SiS
    SI7012 (Alsa mixer)” launched by Menu > MultiMedia > Volume Control >
    Volume Control (Adjust the volume level)

  • volume can not be adjusted by using any slider in YaST > Hardware >
    Sound > Other > Volume

  • the only way to control the volume is with the hardware knob ON the
    speaker itself…and, i have to turn it WAY down…far lower than when i
    (for example) watch at youtube or listed to a CD…

Question: what am i doing wrong?
