Microphone not being recognised by the OS Ubuntu 18.04LTS
My microphone is not being recognized by Ubuntu. If I try to record something, its just random noise. Microphone worked nicely with good quality audio in Windows on the same computer.
onlinemictest.com doesn't even recognize input from mic of headphones.
Windows used Intel Microphone Array for sound input.
In Ubuntu, Device for sound input shows:Internal Microphone- Built-in Audio
