Op http://www.trevorprokop.com/ kwam ik de volgende tip tegen:
This is a quick fix to remove the startup sound played when users log into a Citrix Published Application.
- Download this file. Windows XP Startup.wav
- Replace C:\Windows\Media\Windows XP Startup.wav on your Citrix Presentation Server.
Na het uitvoeren van deze twee stappen ben je van het startup geluid verlost.
Create an policy which restricts audio from server to client for users. Create a second policy for sound-enabled users (if required). Uncheck ‘Disable legacy audio’ at the published application.
This will fix the start-up sound.
replacing a 415K wav file with an 11K file solved the problem in several ways.
this is a good and simple fix (the best kind!).
