Greetings - Recently I have started having problems with the SOUND Command on my primary computer (machine #1 in the list below). When I use the SOUND command synchronously (i.e. SOUND 300,30,,_False), no sound is made and program hangs - I have to Force Quit. When I use the SOUND command asynchronously (i.e. SOUND 300,30,,_zTrue), no sound is made but the program continues. So it seems that the sound is never started, and thus never finishes playing - which hangs the program when it is waiting for the finish (i.e. synchronously). The SOUND Command has always worked before, was working fine several weeks ago on my primary computer (machine #1), and continues to work fine on the 2 other machines that I have tried. I am using FB4 r3, but compiled code from older versions of FB seems to act the same way. I would suspect something in the operating system. The 3 machines I have tried (all are running OS 10.4.7) are: 1. iMac 2.1 GHz PowerPC G5 - 20" screen with iSight (my Primary machine) 2. iMac 1.8 GHz PowerPC G5 - 17" screen 3. iMac 800 Mz PowerPC G4 - 17" screen Additionally, Machine #1 (but not #2 & #3) seems to have developed sound problems in certain other circumstances: -> The quicktime movie of the WWDC 2006 Keynote address (http://events.apple.com.edgesuite.net/aug_2006/event/index.html) has no sound, but the 'Watch "The PC Guy" deliver his own greeting to the attendees of the annual Worldwide Developers Conference' clip does. -> The 'Dancing Comedian' clip posted at <http://www.youtube.com/watch?v=ygOnkXbJXmg> no longer has any sound. ITunes works fine, as do several other quicktime movies that I have tried. I don't know for sure that these events are related, but it seems likely.

Bernie replied: > FYI, "FB sound commands" works here. FB4.2, PowerBook G4 1.67 GHz, OS > X 10.4.4. and then Alain posted: > Merci Bernie, problem resolved with a "LaunchServices database rebuilt" Following this hint, I did the following: 1. Ran the maintenance scripts using 'MacJanitor' 2. Ran 'Rebuild LaunchServices Database 1.0' from <http://scriptbuilders.net/files/rebuildlaunchservicesdatabase1.0.html> 3. Ran Techtools Pro 4.1.2 None of this seems to have had any effect on the SOUND problem. Anybody have any ideas?
