Hi Folks, I have tried to get an answer to this question thru Stackexachange, but they give me bureaucratic reasons why this question does not qualify for an answer. Maybe one of you can give me some guidance. Here is the question: I am running Ubuntu 20.04 LTS. I use this command line to record from either Line In or microphone: sox -t alsa default \Desktop/FTC/RecdMsg$(date +"%Yx%mx%dx%Ix%Mx%Sx%p")x1.mp3 A cable is always plugged into Line In. If I plug a microphone into the Front Microphone connector, this command line records from the mic. If I physically unplug the mic, I can record from Line In. I hope someone can help me: a. Create a similar command that always records from Line In b. Create a similar command that always records from Front Microphone c. Create a command that asks me which input I want to use Thank you.
