Internal Speakers sometimes quits

I have an LC575 runnin OS8 that has internal speakers that do not work half the time. Then suddenly starts to work. I have trashed the sound pref, rebuild the desktop, ran Norton Utilities, adjusted the sound level. It happens in various programs and there is no pattern. Do the speakers need to be replaced or is there a way to get at them to check the wiring?

Your battery is getting weak. Replace it.

The battery was just changed two months ago, so I sincerely doubt that that is the problem. Especially since the time & date is the first indicator of a low battery.

It is a software (or firmware) problem. Your hardware is fine.

Would you like to elaborate more on the software problem? I ran Norton and everything is fine. Other machines with the same programs and same set up are fine.

try w/ a minimum extension set.  also, try trashing your old sound stuff, and reinstalling the appropriate files.  depending on your sytem you'll have differnt stuff.  also make sure you're sound manager extension is current.  the one that is current w/ sys 8.5 is v3.3.
could you give us some more info which sound extensions/control panels you're using?  try Monitors and sound w/ the systemAV extension...

I am running OS 8, Monitors & Sound v 1.3,System AV 1.3. Pref were trashed, still happens. The sound comes and goes. I do have virtual memory off because of a program I run. All other computers have the exact same stuff and they do not have this problem.

I encountered similar problems with a IIsi. The problem is related to the software that you are using and not the hardware. We solved the problem by installing external speakers.

Why would external speakers work and not the internal speakers? To me that would be a hardware problem then.

Why don't you try re-installing OS 8?  or there might be a connection problem with the speakers....

Doesn't work in certain programs?. Or does it work in a program and suddenly stops working?. Or it works one time and not the next and when you access the sound control panel you can't get it to work.

This problem is software related and has to do with how the software you are running accesses the sound resources. Somehow it works different when you attach an external speaker.

This sounds like an old problem the Mac IIsi used to hve. It is a hardware problem but won't cost you a dime.
Open the case. Find the speaker and the two wires coming out of it. At the end of the wires are two spring-like metal contacts. Clean these with very fine sandpaper or an ontioxidant cleaner.

One day of using head phones brought the sound back. The speakers now work. Strange, but it worked.
