Hi, all. I read this discussion group all the time but this is my
first post. Not sure what my problem is -- audio control or internal
speaker. OR could it be some sort of setting issue? I have no sound(s)
whatsoever coming from internal speaker. No alert sounds. No boot up
chime. No music. I tried plugging headphones into headphone jack. I
could hear sound coming from one earphone but not the other. The
external speakers used to work (via mini jack) but I sold them a while
back so I cannot test the mini jack. If I go into my system
preferences, under sound, and select output -- it shows internal
speakers -- but the box is grey. Window below says there are no audio
controls for this device. Curious. I've read up on this and tried
various methods to fix. I have used a slight touch of WD-40 on
headphone jack. Plugged and unplugged headphones 30 times (as I read
somewhere might help.) No luck. I've reset PRAM. I've tried trashing
the sound preferences. Even did a fresh install of Tiger. I have
opened Garage Band and closed. Even tried the toothpick/plastic fork
method of jiggling the external mini jack a bit to try and reset. I've
repaired permissions. I ran the Apple Hardware disk, which doesn't
indicate any hardware issues. Disk Utility shows a Texas Instruments
sound card (device) -- so it is in there. (Just not working.) None of
those ideas have fixed the problem. Wish I still had a mini jack &
external speakers because I'd like to try the plug/unplug method with
that. So, I guess the next step is to replace the internal
speaker...unless anyone has alternate ideas for me. Any last
troubleshooting thoughts/ideas before I purchase a speaker and try
that? Replacing internal speaker seems to be a cheaper, easier avenue.
The audio control is part of the logic board, right? I'd really rather
not replace the logic board in this old computer. P.S. My G4
Quicksilver is NOT my primary computer. Just a "hobby" computer.
Thanks for any advice, in advance.
