This is a simple instruction for newbies about how to fix problem with the sound on Linux, like missing sound from any application, weird static noise from the speakers, or even noise from the microphone when the environment around it is perfectly quiet. I've done this in Mint but as far as I know it should work with all distros.
1. Open terminal.
2. Type
and press enter. This will kill the audio service and the icon from the bottom right corner will disappear. Don't panic - the disappearance of it is completely normal and wanted.
3. Wait for a few seconds and if the icon doesn't reappear, type
This will start the audio service and with it the perfect Linux sound will return.
Note: if the icon did reappear after Step 2, don't proceed to Step 3 or the terminal will return an error and there's a small chance for you to crash the audio service.
1. Open terminal.
2. Type
Code:
pulseaudio -k
3. Wait for a few seconds and if the icon doesn't reappear, type
Code:
pulseaudio -D
Note: if the icon did reappear after Step 2, don't proceed to Step 3 or the terminal will return an error and there's a small chance for you to crash the audio service.
