I have to plugin my USB Audio adapter ( 4300054 Gigawire USB Audio Adapter) for audio input because has a combo-input-output port for voice. After I do this, I have go open Sound Settings and manually select the USB Audio adapter for Input and Output, if I do not, the system default remains selected.

Is there anyway, I can make Ubuntu to automatically select the USB Audio Adapter as the default as soon as I plug-in?

There is pulseaudio module-switch-on-connect that enables automatic switching of an audio device on connection. To test if this works we may issue the following commmand in a terminal:

pacmd load-module module-switch-on-connect

On success we can add the following line to our /etc/pulse/default.pa

load-module module-switch-on-connect

to always load this module on every login, resp. restart of the pulseaudio daemon.
