This machine has many problems. But the latest persisting one is the sound not working. The chime will sound at startup but then no other sounds will work unless the PRAM is zapped. Here is the record I have on file for this machine:
06/18/2001 - Merry muted the machine 6/15/01. Was not able to get sound back Monday morning. Rich deleted Sound Preference and went back into Sound Control Panel. Deleted preference again and restarted machine. This didn’t work as well. Restarted with extensions off. Sound then worked. Restarted machine with all extensions on and was able to get get sound to work. - OK.
06/19/2001 - Sound not present after startup. Restarted with extensions off. Sound was present. Restarted again allowing extensions to load and sound was there.
06/20/2001 - Sound problem same as 6/18 and 19. Zapped the PRAM. Appears to be working.
06/25/2001 - Machine shut down at startup. Also sound was not present. Merry had to restart with extensions off, then restart with them on for sound to be present. Kirk at Computer Hardware has been contacted. He will contact Apple engineer that has been consulting on startup problem.
06/26/2001 - Sound problem - restarted with extnesions off, then restarted with extensions on and sound was present.

06/29/2001 - Sound problem again. Booted from NUM and ran NUM (see above). Sound did not work when booted from NUM disk. Repairs were made, HD was defragmented. Machine was restarted and sound would not come back until the restart w/o extensions the restart w extension. John LaRocca checked the sound input and made adjustments. Will check Monday if that solves the problem.
07/02/2001 - Machine shut down at startup and sound problem ocurred this morning. Contacted Kirk at Computer Hardware Inc. Waiting for response from Apple rep on what needs to be done.
07/03/2001 - Same problem as 7/2. Contacted Kirk at Computer Hardware Inc. It was suggested that a different USB keyboard be hooked up to the machine before the machine is shut down Tuesday. Then start up from that different keyboard Thursday morning. John will look into extra keyboard to do this.
07/10/2001 - USB Keyboard to an old BW G3 was installed on Merry’s machine. Started up G4 without any problem and sound was present. Shut down and restarted in afternoon. Came up fine. Shut down and had machine waiting for Retrospect backeup.

08/02/2001 - John LaRocca opened machine up. Wire to speaker was loose. Also wire connection to board was loose. When holding down the wire and starting up the sound was fine. If not holding down sound did not work. John will solder the connections together.

10/01/2001 - Sound did not come up. Richard restarted with extensions off. Did not work. Restarted, Zapped PRAM and then sound was present.
As mentioned in my notes there was a period for a month and a half where this problem did not happen. I have asked many times if something has changed. A program, a file, anything. Nothing.
Our Authorized Apple Repair Representative has stated that Apple has been stating their normal answer - erase the HD and re-install the system. At the present time it is not optimal to bring this machine down due to a sound problem due to our production schedule. So for the time being I am Zapping the PRAM and getting the sound back.
Anyone had this happen to them?
Any tips, tricks, ideas or suggestions would be great. Thanks in advance!
