** Description changed:

  [Impact]
  
   * Some Intel platform bionic user audio function will be broken after
  upgrade to kernel 5.4
  
   * pulseaudio can't find working profile, since card name is changed in
  kernel 5.4
  
  [Test Case]
  
   * install kernel 5.4 and check audio function
     $ sudo add-apt-repository ppa:arighi/bionic-hwe-edge-5.4
     $ sudo apt-get update
     $ sudo apt install linux-header-5.4.0-31-generic
     $ sudo apt install linux-image-generic-hwe-18.04-wip
     $ sudo reboot
+ 
+  * install updated linux-firmware and pulseaudio
+    $ sudo add-apt-repository ppa:kchsieh/training
+    $ sudo apt-get update
+    $ sudo apt install linux-firmware
+    $ sudo apt install pulseaudio
+    $ sudo reboot
  
   * test items
     1. check internal speaker/mic to playback and record audio
     2. plug headset and check headset functions
     3. plug HDMI from external monitor/TV, and check audio functions
     4. 1, 2, 3 works fine after resume from suspend
  
  [Regression Potential]
  
   * The updated pulseaudio breaks audio function on old kernel
  
  [Scope]
  
   * Need for bionic only
