Update: the troublesome audio CD was not accepted by an old MacBook (OS
X 10.6.8) but WORKED FINE in another MacBook (also 10.6.8).  I also
found a second audio CD with the same issue, which also worked in the
second MacBook.  Could the CDs have bad checksums which the drive
firmware or kernel on the second MacBook somehow ignore?

Title:
  Unable to mount audio disc - Message did not receive a reply (timeout
  by message bus)

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  I have an Asus external slim USB optical drive and when I insert an
  Audio CD, Unity pops up a message with the text in the summary:
  "Unable to mount audio disc - Message did not receive a reply (timeout
  by message bus)".  I'm able to open VLC and successfully play the
  audio disc, so I don't think it's a hardware issue.  I've tried
  checking the box marked "Never prompt or start programs on media
  insertion" in the System Settings in the Details -> Removable media
  section with no change in behavior.

  Here is some hopefully relevant info:
