I am facing a problem where the microphone is recording audio only when it's called by one process. i.e.

I am having a java sound recording application it works fine when i execute it.

Now i am running a flash application where the flash application also uses microphone object.

Once again i am running the same java recording application. but this time it's throwing line not available exception. Recording is working fine in windows and MAC

You might need to install the pulseaudio utilities to manually configure them

sudo apt-get install paman padevchooser paprefs pavucontrol pavumeter

Once that's done, fire up pavucontrol and take a look at the recording tab for details. It's possible you might have muted it on accident. enter image description here
