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 and module-switch-on-port-available that enable automatic switching of an audio device on connection. See with the following command if any of these modules is already loaded:
If not, then test if you can make automatic switching work by issuing one or both of the following commmands in a terminal:
On success add one or both of the following lines to your
/etc/pulse/default.paThis will then always load these modules on every login, resp. restart of the pulseaudio daemon.
Please note that local user settings in
~/.config/pulse/default.paoverride system-wide setting. If you have such a local file you will enter the above commands there.If it still not works you may have conflicting settings in such a local
default.pa. It then may worth to (temporarily) rename this file followed by a restart of the Pulseaudio server before trying above again:
