Voice memo and phone noise

hello my name is Mike,

I am from Germany.

my English is not the best.

But I hope you can help me anyway.

I have an Iphone 3G-S with IOS 5.0.1

It was never Jailbeaked.

When I record a voice memo with the Iphone then rushes the microphone.

The same is also on the phone.

Also the use of the headset does not bring improvement.

I reset the iPhone to factory settings, but without success.

I've replaced the dock connector, but without success.

I replaced the headphone jack with flex cables, but without success.

When I play music, there is no rush.

Only when I play recorded voice notes or phone calls.

Did you have a solution? I'm getting perplexed.

your English is better than mine! I'll have a search and see what google throws out but it may be the noise reduction "inductor"?? near the no4 connector. It's a tiny little part about 1mm long. I think this sounds like a problem that a user called James Bond solved and put a good answer to. Maybe you bumped it off in a previous opening?

Noise during a call

No USB Connection after I broke little SMD element near connector #4!, the part he replaced is labelled noise reduction, i would check this area for damage, also take a look at the connector no.4 pins

I had checked the complete path with my measurement equipment. All Resistors, Coils and Capacitor are in tolerance.

I have the iphone a few days not used.

Then I unlocked the lockscreen and instead of "unlock sound" just came rushing out of the speakers.

I went into the settings, clicked on a Ringtone it was just noise from the speakers. Silently, they heard the sound below the noise.

I then plugged in the headphones, and Try the same again. The headphones can also be heard only noise. I have restarted the Ihpone. But without success.

All connectors are plugged.

The logic board was not measured under stress.

In short:

The microphone, speakers and headphones noise now

I have no more idea :/

Is the Sound Driver "CS42L61A" a QFN or BGA component?
