REVISION SUMMARY
  For modern web browsers, the audio stream isn't owned by the same process as the window, making the mapping fail.
  When no PID is find for a window, check the streams, whether the PID might be actually the parent PID.

TEST PLAN
  - I get audio indicator on Chrome again

REPOSITORY
  R119 Plasma Desktop
