I was using some software that uses microphone , and i had some problems , for example on palava.tv which is a service like skype o google talk you can speak and see your friends for free, without registration.
So i had this problem , the default microphone was the internal one so ….i tried to change it on the icon , like you can see here , and i have even reloaded the page but microphone was always the internal one.
i knew that on gnome desktop you have the ability to change mic on the fly and i was searching a way to do the same on kde desktop , so i tried on system settings multimedia but it was not working at all .
so ? SOLUTION
just install veromix and plasma script engine python :
sudo apt-get install plasma-scriptengine-python plasma-widget-veromix ladspa-sdk swh-plugins
add vermix to your panel and you will be able to change microphone on the fly , i will use palava.tv to show this feature .
so go here with chrome or chromium www.palava.tv/123testkdemic now it will ask to allow or deny just use allow button , if you check VEROMIX now you will see RECORDSTREAM with chrome \chromoium icon just click on the ARROW ON THE RIGHT and click again on MOVE TO ==> so you can select your preferred mic!
