Newly aquired G5 DP 2ghz with 2gb ram running Leopard, which I updated to 10.5.8. Air cooled NOT water. Mostly running quite nicely.
Internal speaker not working thus NO chime or sounds. The headphones work fine. The Sound Preferences output tab lists the build-in-audio (Internal speakers) under choose a device for sound output, and lists optical digital-out port (Digital Out). No device is connected to the optical audio port, and selecting it brings up "the selected device has no output controls." If Digital Out is selected Output volume control is greyed out. If Internal speakers is selected the Output volume control is NOT greyed out, appears to work but has no effect. Internal speaker selection also states "the selected device has no output controls." I have reset the nvram via open firmware, but made no difference. An internet search reveals problems with the optical audio port mostly refer to portable macs. Solutions range from jamming the headphone plug in repeatedly to twisting and turning toothpicks, matchsticks or plastic forks into the headphone port at a particular angle. I surmise that on the portables there is an optical audio switch inside the headphone jack which gets stuck in the on position? On my machine there is red light lit in the port from boot to shutdown. Here's a photo of what the port looks like: http://support.apple.com/kb/TA27095?viewlocale=en_US Pushing the tiny door back on the port does not reveal a switch of any kind, and I don't want to go poking around in there without more information.The connector cable is I think a toslink optical; I don't have one, so it's off to the electronic store. Perhaps, just plugging unplugging the cable will have some effect, if my machine suffers from a stuck on switch. Who knows? I have NOT reset the PMU. A PMU reset always seems a drastic/risky measure to me, but maybe no more risky than prodding and poking the optical audio port itself. Is there a particular kext or bundle that controls the optical audio port, which i could remove/mv or disable? It has to be controlled by some kext, which one? Answers and alternative suggestions appreciated.
