Hi Team,
We have deployed lubuntu in our premises, and have installed pulse audio for 
the sound capability. When we play audio via 3.5 jack or USB headset we are 
facing a lot of distortion and static/humming sound. The distortion happens 
after 4-5 min of playing any audio files , at that point the pulseaudio CPU 
usage goes above 20% and it stays there, moment the usage comes down , sound 
will be normal but again the same happens. Please let me know what needs to be 
checked here.
