Power PC G5 audio is locked out, unworking. How to solve? Have tried Preferences/audio

Recently, my Power PC G5 lost audio after trying to run a damaged DVD. When I tap audio buttons on keyboard, an icon -circle with dash thru it- appears showing sound is locked out though sound level shows completely on at highest level. I have tried Preferences-Audio and no device registers on Output. I have removed any input device wires to no avail. Any ideas please? Thank you in advance.

iMac, Mac OS X (10.5.8)

There's the PRAM reset (same instruction as NVRAM reset) that does

sometimes have relationship to audio issues & their resolution:

Not sure what the actual cause of this issue may be, however it may be

a matter of troubleshooting to attempt to resolve the matter by using the

power management reset to see if that helps. Or at least tell if the problem

is more or less hardware verses software. There are different names that

pertain to the power control chip & reset methods. SMC, SMU, PMU, etc.


There may some chance of helpful response in your iMac G5 by a reset:


iMac G5 (Earlier models).

iMac G5 (iSight, Ambient Light Sensor)


Not knowing the exact model, you'll have to read to see correct method.
