Built in microphone not working - HP dv2109nr

Hi everyone ,

First off, hopefully I posted this in the right place.

Now, I've been having a built-in microphone problem with my laptop. It's an HP dv2109nr laptop, which I posted in the thread title. It uses a built-in dual microphone. I've found that only the left microphone will work. I bought a used, but working one for $1.50 on eBay. It's basically the same, just extra wires to each microphone. The connector which connects to the motherboard is exactly the right one. I bought it because I've found that the wiring to the connector, on the stock one, was loose. Played around with it and got the right one working. But because of the wires being so small, I bought this used one on eBay.

Ok, I've got it installed, but yet can't get the right microphone to work. It's now come down to the MIC1 connector on the motherboard that isn't working right. This is the connector the built-in dual microphone connects to. Right now, I'm stressing out because this problem is involving the motherboard. I don't know where to turn to, so I thought I would post here. Any help or where I should go for help, would be great.

This laptop I've had for almost two years, got it from a friend. Since getting it from them, I've never used the built-in microphone. I never had the need, but now I do.

 

Well I have no idea what you mean by dual mic? That laptop has one mic input.

It's the built in microphones above the LCD screen. It seems that the connector on the motherboard for them isn't working right. I'm just not sure what to do.

 

Just get an external mic. Those built-in mics are crappy anyway.

 

Yeah, that's what I wanted to do. But I was looking for something more portable. With this situation I'm in, I think it'll be hard to get help through typing. I may have to have somebody check out the mic connector on the motherboard. I was hoping for some advise that would help, me, figure out what would be causing it and if I have to replace something. There could be a lot of reasons why the built-in microphone connector on the motherboard isn't working... just not sure what.

I have the laptop fully disassemble to make it easier to find everything. With having the laptop for a while, I'm getting the LCD screen flickering. My friend that gave it to me was having that issue. But I was able to get the plug pushed back in. With the lid being opened and closed the wires get pulled and loosen it from the connector. But I'll see what I can do with the microphone. If anyone has any more advise or know where I should turn to, please reply. If it comes down to it, I'll reassemble and use an external microphone.

 

I understand. You still want to know what's causing the problem. Nevertheless, I only gave my input as an aside. But even if/when your internal mic problem is solved, I still advise you to buy a GOOD external mic and us it instead.

This will be invaluable to every audio recording you make; and it is arguably the most neglected areas when making a recording. You can tolerate poor video, but poor audio makes for a useless and uninteresting recording.
