            Bug ID: 444407
           Summary: Phonon audio notification leaks file descriptors
           Product: Phonon
           Version: unspecified
          Platform: Other
                OS: Linux
            Status: REPORTED
          Severity: normal
          Priority: NOR
         Component: general
          Assignee: unassigned-bugs at kde.org

  Target Milestone: ---

This has been reported by numerous users of KStars. Audio notifications playing
in KStars are leaking file descriptors, often leading to the App failure to
save or generate any new files.

The only warning in the logs we get is this:

2020-09-27T02:15:20.064 CEST DEBG ][                       default] - WARNING:
Phonon::createPath: Cannot connect  Phonon::MediaObject ( no objectName ) to 
Phonon::AudioOutput ( no objectName ).


This was reported mostly on Raspberry PI buster, but also on Ubuntu 20.04. When
on Plasma (KDE Neon), there is no issue in playing the sound or the leaky file
descriptor. Is it possible that failure to play sounds does not clean up a file
descriptor that was prepared to play the sound but then failed?
