no input and output devices detected in sound definitions

[Paulo Jorge Costa Ricardo Barroso]

After installing pulse audio equalizer, it worked good. everything was detected in Sound Definitions and there was sound in the headphone out.

In the day after, every input and output devices were gone in Sound Definition. I uninstalled pulse audio equalizer but nothing happened in Sound Definitions, everything was gone.

I rebooted the system and nothing. No sound.

It appears you don't have a pulseaudio daemon running, which would explain the loss of all output and input.

Please look in /var/crash for any relevant crash files. If found then follow the instructions in https://wiki.ubuntu.com/Bugs/Responses#Missing_a_crash_report_or_having_a_.crash_attachment

Otherwise, please check this page to see what crash reports the machine has automatically sent: https://errors.ubuntu.com/user/ID where ID is the contents of the machine's /var/lib/whoopsie/whoopsie-id file.

When experiencing the problem please also run:

  ps auxw | grep pulse

and send us the output.

I wanna thank you for the time you spent with this.

What I did was a fresh install of the Ubuntu because I needed the laptop
urgently. Everything went back to normal.

Thank you once again for your support. I want to say that I' m very pleased
with Ubuntu.
