Thank you for taking the time to report this bug and helping to make
Ubuntu better. It sounds like some part of the system has crashed. To
help us find the cause of the crash please follow these steps:

1. Look in /var/crash for crash files and if found run:
    ubuntu-bug YOURFILE.crash
Then tell us the ID of the newly-created bug.

2. If step 1 failed then look at https://errors.ubuntu.com/user/ID where
ID is the content of file /var/lib/whoopsie/whoopsie-id on the machine.
Do you find any links to recent problems on that page? If so then please
send the links to us.

3. If step 2 also failed then apply the workaround from bug 994921,
reboot, reproduce the crash, and retry step 1.

Please take care to avoid attaching .crash files to bugs as we are
unable to process them as file attachments. It would also be a security
risk for yourself.

Title:
  Ubuntu crashes multiple time due to pulse audio. (alsa-util.c:
  snd_pcm_delay() returned a value that is exceptionally large)

Status in pulseaudio package in Ubuntu:
  Incomplete

Bug description:
  Description:  Ubuntu 18.04.4 LTS
  Release:      18.04

  pulseaudio:
    Installé : 1:11.1-1ubuntu7.5
    Candidat : 1:11.1-1ubuntu7.5
   Table de version :
   *** 1:11.1-1ubuntu7.5 500
          500 http://fr.archive.ubuntu.com/ubuntu bionic-updates/main amd64 
Packages
          100 /var/lib/dpkg/status
       1:11.1-1ubuntu7 500
          500 http://fr.archive.ubuntu.com/ubuntu bionic/main amd64 Packages

  
  The OS freezes when using in normal conditions, usually VS Code, Discord app 
and Spotify in browser.
  When it does, I need to hard reboot by holding power button.

  I checked journalctl to confirm it was due to pulseaudio.

  alsa-util.c: snd_pcm_delay() returned a value that is exceptionally
  large

  The above line is always the last to prompt in the boot journal.
  It does not freeze instantly, it progressively freezes down, but sometime 
Mozilla Firefox crashes and it freezes no more.
