Thanks to How do you set a default audio output device in Ubuntu 18.04? for the output bit, but I also have several input devices and wanted to share the solution:

pactl list short

Will return a list of devices look for the input device you want. In my case I'm looking for a yeti microphone

In the list I can find the mic I'm looking for:

alsa_input.usb-Blue_Microphones_Yeti_Stereo_Microphone_797_2018_12_05_58600-00.analog-stereo

I can set it as the default device:

pactl set-default-source alsa_input.usb-Blue_Microphones_Yeti_Stereo_Microphone_797_2018_12_05_58600-00.analog-stereo

and if you add that command line to startup apps then you should be golden
