I recently picked up an LC III, when I first powered it on everything worked great, I had video and a startup chime. On about the fifth time I powered it on the startup chime was garbled, and after that it never chimed again. I have also tried headphones, no chime. When I have headphones plugged in and switch the machine on, I can hear a quiet pop like something is initializing. I recapped the logic board and that did not fix the problem. Everything else still works, video is fine, and the machine functions normally other than no audio. I also followed the instructions in the post linked below to check continuity, everything is good. Does anyone have suggestions for further troubleshooting?
Edit: I do not have a PRAM battery, I still tried the PRAM reset as MrFahrenheit suggested in another thread, though I only did it 10 times and not the 11 that was suggested.
