The variable 'shown' is only 0 on first error. - All call sites test the return code of audio_bug(), print an error context message and handle the errror. - The abort() in audio_bug() enables a class of guest-triggered aborts similar to the Launchpad Bug #1910603 at https://bugs.launchpad.net/bugs/1910603.
