1 833 493 0111 How to Fix Mac Error Code 43 on Mac OS

Sounds like either a faulty keyboard or the Ctrl key is stuck.

Please follow the following steps to rectify this problem :

Step 1 .Reset the default BIOS settings:
You can try resetting the sound default in the BIOS. Here's how:
1. Turn the PC on. When the Windows logo first appears, press the F1 key or Dell key repeatedly until you see the BIOS setup screen appear.
2. Press the F5 key ( Setup defaults). In some other PCs depending on the manufacturer the BIOS at start-up will have one of the default options that have names such as - ‘Load Fail-Safe Defaults’ and ‘Load Optimised Defaults’.You will have to choose ‘Load Optimised Defaults’
3. Select Yes or OK, then press the Enter key on your keyboard.
4. Press the F10 key, then select Yes or OK to save the default settings. Press Enter.
5. Exit the BIOS and restart your system checking for sound.
( For most PC's entering the BIOS will be the same but if it differs for your system, consult the operating manual for instructions on entering the BIOS.)

If this doesn’t work go to step 2

Step 2 . Configuring on-board sound in the BIOS:

Some computers come with sound on the motherboard (on-board), and some computers use a sound card. The on-board sound setting in the BIOS has to be set according to your particular sound configuration. Perform the following steps to correctly configure the sound in the BIOS:

Look at the back of your computer and use one of the following three items to determine the proper sound configuration and sound setting:
If the plugs for the speakers and microphones are located next to the parallel, serial, or USB ports, then the computer has on-board sound. The on-board sound setting in the BIOS should be Enabled. If the plugs for the speakers and microphone are located away from the other ports and sit in an area by themselves, the computer has a soundcard. The on-board sound setting (if there is one) in the BIOS should be Disabled. If the computer has sound plugs in both locations, a
soundcard has been added to the computer that already contains on-board sound. The on-board sound setting should be Disabled. To enter the BIOS, turn on the computer and when the first screen appears, press the F1 key /Dell key repeatedly until the BIOS Setup screen opens. Use the LEFT and RIGHT ARROW keys to select the Advanced tab. Press the DOWN ARROW key to select Onboard Audio Options and press ENTER. If Onboard Audio Options is not available, select I/O Device Configuration and press ENTER. If Audio Codec is listed, select it and press ENTER. Select either Enabled or Disabled depending on your configuration and press ENTER. Press the F10 key and then press ENTER to save and exit Start Windows and check for sound. If there is still no sound, continue to the next Step.

Step 3 . Reload the current sound driver

To do this, follow these steps
1.Click Start, type Device Manager in the Start Search box, and then press ENTER.
2.In the Device Manager dialog box, expand Sound, video, and game controllers.
3.Locate the audio device that was included with the computer.
4.Right-click the device, and then click Properties.
5.Click the Driver tab.
6.Click Uninstall.
7.Make sure that the Delete the Driver Software for this device check box is cleared, and then click OK.
8.In the Device Manager dialog box, click the Action menu, and then click Scan for hardware changes.
You should see a message that a hardware device is being installed. Additionally, the uninstalled audio device is now present in Device Manager.
9.Close the Device Manager dialog box, and then determine whether you can hear sound.

If your computer came with a motherboard CD, the audio drivers should be on the disk.

If you don’t have the CD go to your computer manufactures web page to search for updated sound driver software. Read the instructions on the download pages carefully
before installing.

If there are no updated sound drivers available, use Microsoft's Windows Update feature. Connect to the Internet and try the following items until Windows Update opens:

1.Click Start, and then click Windows Update (if it is listed).
2.Click Start, click Settings, and then click Windows Update (if it is listed).
3.Click Start, click All Programs, and then click Windows Update (if it is listed).
4.Go to Microsoft's Web site and click Windows Update from the Downloads menu.

Check if the sound works now….if it still doesn’t work then most likely the sound card might be faulty.

About fixed dialing
If you enable fixed dialing number (FDN) mode, your device only makes calls to contacts on your FDN list. Your device can dial emergency numbers in FDN mode, even if the numbers are not in the FDN list. If your service provider plan includes SMS, you can also send SMS messages to contacts on your FDN list

so if you have this enabled chances are you have to turn it off.
this is how you turn it on so you should be able to use it as a guide to turn it off.



Turn on fixed dialing
1. In the phone options, click FDN Phone List.
2. Click the trackwheel.
3. Click Enable FDN mode.
4. Type the PIN2 code provided by your service provider.
5. Click the trackwheel.

or if you wanna keep it on and add friends to the fdn



Add contacts to the FDN list
1. In the phone options, click FDN Phone List.
2. Click the trackwheel.
3. Click New.
4. Type the PIN2 code provided by your service provider.
5. Click the trackwheel.

3. Press the power button to turn the system on while holding on the "Fn" key.
4. Run the PSA until you get to the "colored bars". Then press "N" to say no.

Now if your hear beeps that means that there's something wrong with the driver and audio settings. Do the following:

1. Right-click on My Computer then click on Properties
2. Click on Hardware then Device Manager
3. Click on the (+) beside Sound and Audio Devices
4. Right click on Sigmatel then click "Uninstall".
