The internal speakers for my powerbook g4 have stopped working. When i go to the sound panel to select them for audio output, they do not show in the options to select. Please, someone help, i cant afford another laptop.
PowerBook, Mac OS X (10.5.8)
You could try & reset the PRAM (parameter random access memory) since that may have a
bearing on built-in audio volume and other settings in a PowerPC Macintosh; this reset is
similar to the NVRAM (non-volatile random access memory) used by Intel-based Macintosh.
Some support articles tend to mix these, so you can find PRAM discussed in Mavericks 10.9
for unknown reason, and NVRAM discussed in reference to earlier Intel-based OS X, too. Both
use the same keyboard shortcuts, and appear to perform similar reset functions.

Another reset that may help, unless the problem relates to logic board issue, is PMU reset:
•Resetting PowerBook and iBook Power Management Unit (PMU) - Apple Support
So to try the PRAM or NVRAM type of reset first, as the settings may be corrupt; as last resort,
Power Management Unit. In the PowerBook G3/G4 and iBook G3/G4 utilizes different instruction
on how to reset this, read to be sure you choose the correct method for the computer hardware.
Desktop models use different instructions, some have a process while others include a button...
Later hardware, such as PPC G5, & more recent Intel-based Mac, have a different named process.
Has there been any headphone jack of incorrect proportion been inserted into the audio port, which
may have damaged the micro-switch inside the jack - and cause speakers to not get the signal?
The answer may be software or hardware.
Good luck & happy computing! 🙂
Resetting the PRAM did help! Thank you!
Glad to hear you were able to resolve the issue...! 🙂
