Cannot Record Audio From "line-in" as the Source
by Steve R. from LinuxQuestions.org on (#4X583)
I'm going to take a stab that this is really a hardware issue as opposed to a software issue. I am attempting to record audio from a cassette recorder where it is plugged into the "line-in" jack.
I can hear the audio from "line-in" on the speakers, but when I attempt to record with Audacity (version 2.3.3) all I get is a very loud crackling static. I am also using PulseAudio Volume Control and the volume bar, by going up and down, implies that an audio signal is being processed. Additionally, I can hear sound out of the speakers.
The computer is dual boot. I tested imputing audio from "line-in" under Windows10 using Audacity and it successfully recorded the audio from "line-in".
Under Linux, I am using Mint 19.3. The kernel being used is: 4.15.0-72-generic
