Sound card broken? No normal sound and a constant buzz...

Today when I tried to record music via my mic/line-in jack (which I've done many times before and never had any issues with) there was some short buzz and after less than a minute the laptop started to buzz without a stop. I tried rebooting and just in a few seconds the buzzing started once again. I did a great amount of troubleshooting, checked all the devices, drivers, updates, etc. Nothing worked. Then I came to realise that no matter how I set the volume I can't get any sounds from the external/built-in speakers nor from the earphones...Now, everything else seems to be working fine, except for the fact that the buzzing is still here and that I have no other sound whatsoever... I'm really confused and desperate.

Re: Sound card broken? No normal sound and a constant...

Sounds like you tried everything possible. Based on what you have stated that you tried already I would agree with your diagnosis of a bad sound card.
If this was my Laptop I would be looking for a nice set of USB speakers and Microphone or a headset.
You can either keep the speakers turned down or you may be able to disable the onboard sound through a BIOS setting.

Or even better. Here is a USB sound card with speaker and microphone jacks. Pretty Cheap too.

Background noise on vocal track

There is no doubt that sound on PCs and laptops can be a pain, and I have had to run a mixer output through the mic socket before now, such is the insensitivity of the PC's inputs. But you have done this, which implies that the mic input is not being connected to the sound system. You should have some controls of the way the sound is connected - try the Control Panel (assuming you have Windows) and opening up the sound applet. You won't get anything through Audacity etc., until the system is delivering. Sorry I can't be more specific.

Microphone not working

Hello Weber913,
Below are steps to troubleshoot and resolve your microphone issues. If you have any further questions you can email at my email address listed below.

Test the Microphone

  1. Click Start, point to Programs, point to Accessories, and then click Sound Recorder.
    In Windows XP, you will need to select Multimedia (or Entertainment).
  2. Click the Record button, and speak into the microphone.
    The green waveform should react to your voice.
  3. To end the recording, click Stop.
  4. To hear your recording, click the Play button.

Check physical connections

  1. Verify that the microphone is connected to the red microphone jack for the sound card on the back of the computer and not the microphone jack for the modem. The microphone will not record if it is connected to the Mic jack on the modem.
  2. Test the microphone on another computer using Sound Recorder as in Step 1.

Check the volume control and mute properties.

Double-click the Speaker icon in the System Tray.

  1. Make sure the Volume Controls (or Master Out controls) are at least midway on all levels.
  2. Make sure there are no checks in the Mute boxes.
  3. Test the microphone using Sound Recorder as in Step 1.

Set Recording to Mic/Microphone

  1. Double-click the Speaker icon in the System Tray
  2. Click Options in the menu at the top of the window.
  3. Click Properties.
  4. Choose Recording in the Adjust Volume For section. Do not choose Playback in the Adjust Volume for section. Choosing Playback in conjunction with unmuting the mic may cause loud feedback during recordings.
  5. Ensure that Mic/Microphone has a checkmark next to it.
  6. Click OK.
  7. Test the microphone using Sound Recorder as in Step 1.

Reinstall Sound, Video and Game Controller Drivers

  1. Click Start, point to Settings, and then click Control Panel.
  2. Double-click System and then click the Device Manager tab.
  3. Click the plus (+) sign next to Sound, Video and Game Controllers.
  4. Click each entry one at a time and then click Remove, repeating the steps until the Sound, Video and Game Controllers category is removed.
  5. Close all open windows.
  6. Reboot the computer.
    The sound card will be detected and you will be prompted to reinstall its drivers.
  7. Test the microphone using Sound Recorder as in Step 1.
Thank You,

The microphone jack of my Dell Inspiron 1100 seems to be malfunctioned. When I plug in a microphone, the other side does not hear anything. I tried several different microphones and none of them worked....

Check if the correct recoding device is selected on sound properties, and verify if mic is mute.Test mic using the sound recording program.
Try to uninstall and reinstall the sound driver.
Perform diagnostic on the audio using the drivers and utility disc. if mic is not working on the diagnostic tool then need to replace the sound card.

Dual microphone issue


Technically you can not do this. Most sound cards only support one recording device at a time, especially notebooks. With notebooks usually when you plug in a device it will over ride the build in one.

Now some sound cards give you the option in turn all recording source at the same time so if you laptop would support both mics then you could use this option. The down side is you will be recording from ALL source so you will not want any other sounds going on that you do want in you recording. The steps below will help you check this.

***Note step 4 may not say Analog Mix but if it says mix then most likely you have the option to select all your recording sources.***

4. Insert a check to the left of ANALOG MIX.
5. Click OK.
6. Insert an X beneath ANALOG MIX.
Everything being output via the speakers is now the recording source.

Another option is get a notebook card from Creative Labs as they make sound card. Now if you are doing highend recording you might also look at their highend EMU products as well. I included the links to both there sites.

Let me know if you have any questions

Sound is coming out like broken speakers when using stereo input

The sound card would almost certainly fix the problem. One thing to do is to try a program like Audacity which will help you determine where the problem is. Then try it with your mic setup as it is.
