I think I damaged my mic trying to clean it with an old tooth brush and some alcohol, I recorded some voice notes to test it an it sounds crackly, buzzy and barely picks up my voice. Now I'm looking for a replacement and don't know if the microphone is located on the USB charging board or should I replace the speaker. The speaker works fine, but I don't kwon where the mic is located.
I would be grateful if someone could tell me

Hi,
Please, I did do a number of searches!
I get sound through headphones and Bluetooth Car Kit, but I get no sound through the built in speaker, unless;
I push the USB speaker connector just part (not full) way into the socket. Sound is then normal through the built in speaker. Looks like a h/w issue and the unit is out of warrenty so any 'savage' suggestion for a fix would be appreciated.
Anyone else noticed that the mic is muted whenever you plug something in the audio jack? This means if you are plugging your phone to the aux port in your car, you can't make/receive calls unless you unplug it. On the focus it worked fine. You can test it by starting a call, then plugging anything to the jack - mic is muted right away. Couldn't find any settings to override this either.
I don't have that issue. I plug my phone into the aux port all the time and it works fine.
Yep

I have the same issue. Was great to have a conversation while plugged into the car audio with the Focus. Now we're limited to the speakerphone, which just isn't loud enough to be useful. Maybe when the Diagnostics app gets mapped out better we'll find a setting...
Probably gonna buy a cheap headset, cut off the ear buds and splice the wires to a cable with a 3.5mm jack.
It would make sense for the internal mic to be shut off when a headset cable is plugged in, since the working assumption (I guess) would be that there is a mic on the headset taking over. It's most likely a 'mechanical' shutoff in the jack itself, with no 'checking' to actually see if there is a mic connected on the cable or not.
The issue is, the old focus, the Titan, and about all other cell phones don't do this. They allow the internal mic to work while using the 3.5mm jack.

Hello,
I hope you can help me here.
I have changed the entire case from the htc one.
Since then the bottom speakers dont work.
I've checked all contacts and Pins.
A second microphone board and speaker but nothing work..
The bottom speaker dont work..
For testing,
I cut the wires from the speaker and connected it to the upper speaker.
Then it works perfectly ..
Is there a separate chip for the bottom speakers?
Or can someone give me the points on the main board to call him to solder directly?
Only one speaker is not really true.
Thanks!
Excuse me for my bad english
I have 2 z3c's. The first one (black) has a broken magnetic charging port. Everything else is perfect.
Because I hate the USB charging flaps, I bought a 2nd z3c second-hand. It worked fine for a few weeks, now when I plug in headphones it only plays from one side (whether it's music or in-call). The stereo speakers work fine when no headphones are in.
Have tried multiple headphones, all the same issue. Assume it's an audio jack problem - any ideas?
Looks like audio jack problem by your description.
The contacts are visible inside with direct light pointed into the jack, you can check what's wrong visually. Might be just a bent contact, and precise work with sewing needle might cure it. Might be something broken, and then no good suggestions besides using BT headphones. Or, if you have good headphones and just want a BT adapter, maybe something like this.
Hello all,
So the main microphone of my z3 compact came off the motherboard along with the solder pads. Now i can see a tiny little metal connection exposed on all the 4 pads. I ordered a microphone, soldered it back on the board, but failed all microphone diagnostic and service menu tests. I de soldered the mic again, to see if the contact were lose. While removing the mic, i could see that one of the two pins of mic on the motherboard are shorted, unfortunately the little track came off as well. Anyway, i soldered the same mic again on the board (using a hot air blower), shorted the two pins on the mic, but it still does not work. Now my questions:
1. While testing the microphone, i might not have connected the headphone flex connector to the motherboard. Is the primary microphone somehow routed through the flex connector of the headphone jack?
2. Where is the secondary microphone?
3. Any work arounds, if i cannot solder the mic back on? Can the connections be bypassed somehow with jumper cables etc?
Any advice will be much appreciated. I just dont want to get rid of the phone.
