Ok I have a 3gs 16gb that the sound is randomly cutting out. I get a loud static sound from speaker and then the sound cuts out. The phone then either reboots or just has no sound from speaker,mic, or earpiece. When I make a phone call the phone will connect but I cant hear them and they cant hear me.
I have since restored phone to factory and the phone still made same noise and reboot itself. I have updated software to latest version 4.3.5 but was occurring on 4.3.3 as well. I have opened phone to check connection of ribbon cables and all appear to be good. I checked for the two capacitors above the #4 cable and they dont appear damaged.
I've seen multiple posts with similar problems but no answers. As far as phone being opened replaced battery about 9 months earlier and had no problems with phone till recently. Phone was not dropped or wet. Thanks in advance, Steve

Sorry, can't offer any suggestions. There may be no solution.
It sounds like a hardware ... the motherboard

Yeah sounds like the logic board.
the only way to know for sure tho is by replacing all parts that are acting up
