Microphone jack not working - MSI Computers & Internet

Wiring a Delta M3 microphone to a Cobra 29 LTD Classic CB radio requires connecting the wires from the microphone to the corresponding pins on the radio's microphone jack. Here are the steps:

1. Locate the microphone jack on the front of the Cobra 29 LTD Classic CB radio.
2. Examine the Delta M3 microphone's wiring. It should have four wires: a black wire, a red wire, a white wire, and a shield wire.
3. Determine the pin configuration of the microphone jack on the Cobra 29 LTD Classic CB radio. The pin configuration is usually printed next to the microphone jack or in the owner's manual.
4. Connect the Delta M3's black wire to the pin on the microphone jack that corresponds to the radio's ground connection.
5. Connect the Delta M3's red wire to the pin on the microphone jack that corresponds to the radio's positive voltage connection.
6. Connect the Delta M3's white wire to the pin on the microphone jack that corresponds to the radio's audio input connection.
7. Connect the Delta M3's shield wire to the pin on the microphone jack that corresponds to the radio's shield connection.
8. Test the microphone by speaking into it while monitoring the audio output on the Cobra 29 LTD Classic CB radio.

Note: If you are unsure about the wiring or pin configuration, consult the owner's manual for your CB radio or seek assistance from a qualified technician. Improper wiring can damage your radio or microphone, and may result in poor audio quality or no audio at all.

First, did you plug in the microphone when the computer was off or not? If you connected the microphone while the computer was on, it may not have seen the new device to load the drivers. If the computer found the microphone when it was turned on, then the problem could be driver or hardware related.

You need to make sure that the computer is seeing this as the recording device. Click Start and select Control Panel from the right hand column. Click on the Hardware and Sound link. Select the Manage Audio Devices link under Sound. Click on the Recording tab. Is the microphone listed as plugged in? If it isn't, then the microphone isn't making good contact with the jack, has a bad wire or the jack isn't working. If you have another computer, check if the microphone works on it. That will rule out the microphone being faulty. Next go back to the starting Hardware and Sound Control Panel. Look for the link to the Device Manager under Devices. Expand the section for audio inputs and outputs. Check for a red triangle with an x or yellow triangle with an exclamation point. This indicates a problem with the audio drivers. Check with Toshiba for the audio drivers for your computer and the current service pack for Vista. You may need to uninstall the current driver and then reinstall that driver. A final option may be to check if the external audio input was disabled in the BIOS. When you turn on the computer, you should see a screen that tells you how to access the BIOS. (Usually this is F1, Esc, Del or F2). I find pressing the appropriate key repeatedly after turning on the computer doesn't always work. If you get to the Windows splash screen, turn off the computer at the login screen and try again.

If the microphone is plugged in, set it as the default device. You should be able to record with your software.

If the microphone still doesn't work with this computer and does work with another machine, you will probably be better off using a USB microphone or a USB audio adapter (USB to 3.5 mm microphone and speaker jacks). The wiring of the jack is probably faulty and it's not worth the effort to repair.

I hope this helps.

When you say headphones do you mean the music headphones, like speakers, because they go in the headphone jack in the computer while microphones go in the microphone jack. The microphone is normally a pink color and the headphone jack is normally green. If you already knew this try wiggling the microphone to see if there is a brake in the wire, if that dose not make it fissile in and out then its something wrong with the microphone its self and should be replaced

Look for the sound card on the back of the computer. This will have a 15-pin connector and several colored jacks.

Locate the microphone jack. Although some manufacturers will stray from the norm, the microphone jack is typically colored red or pink and/or will probably have a picture of a microphone.

Connect the microphone into the jack.

Click "Start," then click "Control Panel," then click "Hardware and Sound," then click "Manage Audio Devices" under the "Sound" category. This opens the "Sound" window.

Click the "Recording" tab. Here you will see a picture of a microphone. To the right of the picture should be a sound bar.

Test the microphone by speaking into it. If the sound bar lights up, then the microphone is plugged in correctly and ready to use. If the sound bar remains gray, then there is no signal. Try another jack on your sound card and repeat the steps to test your microphone. If you still can't get the microphone to work review your computer documentation or contact the manufacturer's technical support.

Yes. You should be able to plug it in it your microphone jack. First, find the mic jack. it should be located right next to the headphone jack. Open your sound dialog. You can find it by right-clicking the volume control and selecting recording devices. Look for your microphone in the dialog. It should have a green tick on it. If it doesn't, select it and click "Set Default". (note: your microphone may not show as a separate entity. if not, select your default microphone and test it by speaking into the MV29. The level should change)

the simple answer is No. The long answer is your laptop/computers headphone output and mic input are completely separate on the sound card. Meaning there are no tie to the audio in on the heaphone lines, and vise versa on the mic/line in. Sorry to disappoint.

Sound and Recording jacks stop working on the DV6000 series due to the ribbon cable running under the power button. when the power button is pushed it bends the flex cable and over time it breaks the connection rendering the front jacks useless you can buy a new upper button panel for about 20 dollars on ebay

I'm just taking a stab in the dark here but bare with me on this, I got a lot of info stored in this old head so it takes a while.

If you look at the jack for the microphone, Does it have 2 sleaves and a pin or just 1 sleave and a pin. If it has 2 then you will need an adaptor (Normaly Stereo jack to XLR). If it has 1 sleave then your going to need a preamp.

the jack of your pc has a hardware fault ,so it is not accepting the microphone.

There is an error in the MobilePro 900 manual (Pages 2-2 and 2-3). The jack on the front of the MobilePro 900 is a stereo headphone jack only. The MobilePro 900 has a built in microphone. There is no jack for attaching an external microphone.
