Try this;
- Open the Control Panel - Open the Sound and Audio Devices folder - Click on the Audio tab to find the name of the sound system manufacturer. 
Go to their website and download the latest driver software, reinstall it and then look to see if you now have access to those inputs.

When using my Skype to Skype, Why do I get Feedback ie. Echo ?


Hi Steven
Feedback is caused by the Microphone being too close to the Output speaker.
Feeding Back.... output to input.
Cover the microphone to see if it stops.
Echo may be something else...

I want to use my rode podcaster on my Chromebook. Why isn't it working?


The podcaster needs to be activated for it to work on the Chromebook. the way to activate it is:
  • Microphone settings are found in the bottom right area of screen with clock, wifi and battery indicator on it.
  • Click on that, you will see a volume slider.
  • If you have more than one input or output device connected, there will be an icon to the right of the volume slider that allows you to select options.
  • This will verify if your microphone works.

How do I record tapes using a 552C series?


You want to record audio tapes? You need to convert the headphone output into a higher impedance output to plug into a microphone plug of a tape recorder. If you just use a cable to connect the headphone output to a microphone input you may have distortion because of impedance matching problems. You'll find if you turn the computer volume down nearly all the way it will work OK, but if you want to preserve the fidelity of the sound it is better to match impedance.

All you need for this is to either buy a cable which is meant to convert line out to mic in, or, just use some resistors.

I recommend the 'simple resistor divider' circuit at this link http://electronics.stackexchange.com/questions/29564/circuit-to-convert-line-level-to-mic-level

which uses a 100 ohm resistor and a 10 k resistor. For stereo you will need 2 of these, the outer case of the wire is shared by both circuits, and will play the role of the bottom wire in that drawing for both the inner wires playing the role of the top wire (hope that's clear, if not, anyone knowing a little electronics will be able to help you).

Low sound but my speaker is 100


Check the sound mixer for a low volume slider. The output may be high but if the microphone/mixer volume is low, the output will be low.

Hi,my built in microphone not working ,on laptop aspire 6930g can you help me,i am not very good with computer


I think you are using Windows XP.
Go to Start - All Programs - Accessories - Entertainment - Volume Control
See if there is slider for Microphone & Mute button.
If it is not then go to Options - Properties in Volume Control Menu
Make a check mark against Microphone. Say OK.
You will find the Microphone slider & Mute button.
Remove the check mark against Mute if it is there & advance the Microphone slider control to your required level. Your microphone is ready for use.

Where is the line in jack for my Gateway MC7321u Notebook? Is it one of the headphone jacks?


Some computers have a special jack labeled line in. If your computer does not have a line in jack, you can use the microphone jack. You can then adjust the volume of the device in control panel under sound options. The headphone jack is only for output. I have seen some computers where you plug in a cable to the microphone jack and you will be asked what kind of device it is.

Downloaded skype. I can receive and hear the calling party, but they are unable to hear me.


This is the issue regarding the Internal Microphone in the Computer.
Your contacts cannot hear you, until you have enabled the Microphone in the Computer.
You will find the information to enable the Microphone below:
Windows XP:
1) Double-click on the Volume Control. 2) Select the "Properties" option from the "Options" menu. 3) Select the "Recording" option in the "Adjust volume for" section. Click the OK button. Check the box labeled "Select" under the microphone volume and you should now be able to adjust the volume for the microphone.

Windows Vista:

1) Right Click the Volume Icon at the bottom right corner of your screen [The Task bar]. 2) Click [Playback Devices]. 3) Right Click the [Speakers] Icon and click Properties. 4) Click the [Levels] Tab; and there you will see the Microphone Volume slider (The one at the very bottom of the "HD Audio output" and "PC Beep" sliders where you can un-mute the mic playback.


Windows 7:
1) Click on Start (the Windows icon) and type sound. 2) Click on Sound under Control Panel. 3) Click on Recording tab. Select Microphone and click on Properties. 4) Click on Levels tab. The default Microphone Boost is set to 0. Increase it. 5) Close all the dialog boxes, and the microphone will be ready for use.

Hope this helps.

Volume too high on Dell 1525 webcam


If you are running Windows XP or VISTA, "right click" the speaker icon in the lower right part of your desktop. It is on the right side of the taskbar. Go to "Open Volume Mixer" where it should have individual sliders for "Microphone" "Master Volume" "Line In" etc. Try lowering the "Microphone" or "Line In" volumes to a better level. You'll know which one to move if you try to speak or make any sound into the microphone of the device you want to adjust, you'll see an indicator bar next to the slider move, depending on how loud you speak. Oh, make sure the program you are trying to run with the cam is on and the cam is up and running.

If you have Realtek HD Audio like I have, there will be 2 speaker icons in the same taskbar, one red, one silver/gray. If you have that, then use the red one (Realtek) and go to sound manager. Open the tab of the device you want to adjust and do the same thing, adjust the one that is giving you problems. Here there will be 2 sliders, one for playback and one for recording. Try the playback first or mute it completely, that should help.

If you are still having problems, reply with a comment in this thread so I can find it easier. I hope I could help you get started. Good luck and don't forget to rate! Thank you!
