Since installing Ubuntu 18.04 my headphones have been making an unpleasant popping noise. It is short and usually happens when sound starts (e.g. when I press play on a youtube video). Other times it happens seemingly randomly. It's very annoying and hurts my ears, please help me solve this! Thank you.

  • Hi! Please provide more information about your hardware. What is the machine's make and model? Please read this answer and [edit] your question to include the output of the two commands under the "audio" section. A screenshot of alsamixer would also be helpful. Thanks! – Seth Sep 26 '19 at 18:21

I had the same problem and reinstalling pulseaudio helped me, but not completely, i hear this sound in headphones once on system startup.

My sound card info from lshw:
