    This is worked for me... After all kinds of troubleshooting the problem for me was caused by google voice...  (If you don't use google voice with sprint then this is not the solution)  I had google voice enabled on my sprint phone number ( it wasn't the google voice app) but when someone called my phone google voice was involved one way or another... This is my best guess - I could be wrong - but since I disabled my sprint number from google voice I haven't had any problems.

    A week after paying Apple for a refurbished 4S I ran into this "audio compiler" related defect.


    It is described here: l


    "If this audio compiler doesn't work, then the person on the other end will not hear you - or they will hear a very muffled voice, or a lot of static. Due to what is largely believed to be a manufacturing error in Apple's Chinese factories, a number of iPhone 4 models were assembled with this tiny chip soldered to the mainboard (motherboard) improperly. Either too much solder or glue was used, and the connection is tenuous at best.


    The problem is that the phone could work perfectly for a very long time, and then after a drop (even one that doesn't break the glass), a hard jar, or even for no reason at all, this chip loses its connection to the mainboard and causes the problem you may have experienced."


    I will return the phone to the Apple Store. Hope they believe me. It is erratic on this phone, but I'll try to catch it on video.


    Assuming the manufacturing error was a cause Apple should do a recall.

    J. Faughnan,


    I have opened my phone numerous times and replaced the dock connector twice. Both times failed to fix the audio problem with my phone calls. People can here me blow into the phone on a call, but that is all. However, when I use voice memos the audio recorded is very faint. Should I sell my phone and assume it is the audio compiler?

    Hello Daniel,


    Just for your information: When my iPhone 4S was rather new, I have experienced similar problems (also posted in this forum), but after while the iPhone 4S was functioning normal and I never experienced the problem again.

    I never found out what the real cause for this problem was. It may have been as simple as the SIM fixation in position.

    Anyway, it's really annoying having this issue, but it doesn't mean will never operate correctly anymore due to this defect. (assuming we talk about the same cause)

    I have Google voice too and an incoming message from it was how I learned I couldn't get calls ore make calls after my update today.  I went to the Sprint store and they reset my phone account and it now works.

    The person who explained that this problem was due to a failure to connect to the TSP's network was right, I'm sure. My phone had the same issue. But as soon as I switched off my local signal booster (Home Sugnal from my TSP) and re-started it all was fine.

    I have the same issue (mic not wor only during regular call, using app like Skype, Viber etc. is work fine) and I found only hardware solution like reball the audio compiler ic.





    Sometimes help well embed piece of plastic between chip and shield. This can fix connection between chip and  motherboard by pressure.





    I was looking for some software solution to get round this problem with audio compiler so calls will be performed in the same way like in case of Skype, Viber or any other app.

    I think, this can be elegant solution... However I didn't find anything.

    This is very common issue and Apple still do nothing, like the problem is not exist. I know that this is not good for reputation but be quiet is much worse!.

    Am having the same problem with my iphone 4s 16 gb. My phone is about 16-18 months old and i cannot hear the caller on incoming and outgoing calls also but i can hear on Viber, Skype and other applications. Having took it for repair at my local iphone dealer in my local country but they said it cannot be repair as the circuit board is damage and also cannot be replace as the guaranty is expired and they cannot do nothing to help. Please guys tell me what should i do now with this phone?? Is there someone can help me? This is an expensive phone and i think that the service also should be reasonable for the customer.

  • Starryskye1980 Level 1 (0 points)

    I just purchased the iPhone 4S yesterday via Sprint (my carrier). The internet and texting work fine, but I was getting dead air for both outgoing and incoming calls. I never had an issue with my iPhone 4, even when I had it upgraded to iOS 7.0. I disabled Siri, did everything that was listed on and this site, and now I can make and receive calls...on speaker phone only!

    It is a new 8 GB 4s, running on Sprint's network. Should I fight with Sprint for a replacement?

    Hi Everyone,


    I had the Same Issue and I fixed it twice with simple steps.


    1. Under the phone there is one mic gap (Between 2 open mic:::::=::::::.) one in RED.  Over a period of time the dust can block the mic. Clean it but using small screw driver then it will work.



    2. Open the phone and just press the mic layer and close and it will work.



    3. See the sound setting and max it max


    Mostly it is first of second should work.

    Had this problem - phone is 2.5 years old - appeared a couple of days ago.  I solved this problem with the following - don't know what part actually fixed it.

    1. Disable Siri

    2. Perform soft reset.

    3. Check to see if ring audio on outbound calls working - Yes

    4. Enable Siri

    5. Check to see if ring audio on outbound calls working - Yes

    6 Check to see if Siri working - Yes.


    Mystery of course is what sequence disabled the outbound ring audio in the first place.
