There is a problem with the automatic PA announcements on all 22k units operating on the Docklands-M3 Parkway services. The clip that should play for the Irish name of Hansfield Station is a horrible electronic noise instead. I have attached a recording below(caution, don't listen at high volume).

This has been ongoing for a few weeks, can we get it fixed?
