Comment 0 for bug 878362

After I unplugging external speakers, volume (loudness) of sound on laptop speakers is very low although it is set to 100%. This only happens if both, analog headphone and analog speakers ports are set to 100%. To get loudness back, I have to change master volume of analog speakers below 100%.
