Brian, we have a Vcs for ubiquity which has branches for stable 
releases. Could you please commit this change there?

If you're confident enough to give this to users on focal, then I think 
it would be appropriate to upload to devel as well.

Cheers,

Title:
  No sound in ubiquity-dm with nomodeset

Status in Release Notes for Ubuntu:
  Fix Released
Status in ubiquity package in Ubuntu:
  Triaged
Status in ubiquity source package in Focal:
  New

Bug description:

  [Impact]

   * When booting to "Safe Graphics" mode the system startup sound would
     sometimes not be played

   * This is an accessibility issue as the system startup sound is meant to
     indicate that Ubiquity is ready

  [Test Case]

   * Boot an installer image to Safe Graphics mode and listen for the
  sound

   * You can optionally use `systemctl status sound.target` to monitor when the
     sound should be played. This should occur shortly after sound.target becomes
     active

  [Where problems could occur]

   * If sound.target never comes up, the system ready sound will not be played.
     This could be caused by a missing or broken sound card

  [Other Info]

   * It is expected behavior that the sound target may take longer to become active
     when nomodeset is on the kernel command line. This is because nomodeset prevents
     the kernel from pre-loading audio drivers.

   * This problem seems to be more prevalent with Intel sound cards

  [Original Description]
