I’m using Ubuntu 18.04 installed on a laptop (Toshiba Satellite L675D-S7052) with an internal microphone. When I use the terminal to record a sound sox -t alsa default ./recording.wav, or use discord, I can hear a loud crackling / popping noise during playback. I’ve tried the many options (noise / echo canceling) by editing the etc/pulse/default.pa file with no success.
I’ve also tried lowering the microphone input volume under “settings”, but regardless the input level bar still jumps randomly in a very quiet room.
Any ideas?
Thanks in advance.
Edit: Audio and video files play without any distortion. The microphone worked fine with Windows 10. I've also tried an external microphone that yielded the same results.
