Question about Toshiba Satellite L500 Series Notebook

1 Answer

Every time you turn the volume up there is feedback. We are not sure but it may have started when our daughter plugged an external microphone in to the microphone jack, now we can't get rid of it.

Logitech speaker feedback


Feedback is a sharp, loud noise that can come through the earphones of a headset unexpectedly---it occurs when the headset is getting sound (feed) from someone else speaking or playing music into a microphone. This sound can create a dangerous situation for someone who is operating expensive equipment or flying a plane at the time since it can disable hearing temporarily.
If you experience feedback often, it could also lead to serious hearing problems.

Mic Too Close to the Speaker or Volume Too High
The main cause of a feedback sound in a headset is proximity to a speaker. If a person holding a microphone on the other end gets too close to a speaker, it creates a loop of re-amplified sound that results in the loud, screeching noise. When the volume on the other party's microphone is too high, it is more vulnerable to picking up unwanted noise and feedback from speakers and sound output devices in the room. So make sure that you ask the other party to turn down the microphone to a normal level and stay far from speakers. b> Two Microphones Gathering Same Sound b> When the other party places two microphones too close to each other, it could cause feedback. When positioned toward the sound source (such as a person speaking) the microphones will both pick up the same audio and compete with each other when creating the output of sound, causing a sharp noise in your headset. This problem, called acoustic phase interference, is resolved by simply ensuring that the other party uses one microphone at a time. Poor-Quality Headset or Microphone b> One common cause of feedback is simply a poor-quality headset or microphone. Most modern headsets and microphones have noise-canceling features that manage and kill feedback before it has a chance to occur. These noise-canceling headsets are essential for pilots and aviation crew members. If you hear sudden feedback that is strong enough to hurt your ears, the headset or microphone is simply not properly equipped to actively cancel that unwanted noise before it hits your ears. Buy a higher-quality noise-canceling headset to manage the feedback noise when you're going about your tasks. Hope this helps.

Audio will play on internal speakers only


Are you plugging the external speakers into the right port? Try plugging them into the Headphone port if there is no external speaker port. Make sure you have the external speakers turned on and the volume turned up. Also make sure you have the software in the computer to have the volume turned up and not muted. Check the audio sound properties and make sure the volume is turned up and not on mute.

Click Start/Control Panel then look for Audio or Sound and check the volume.

You can also click the megaphone at the bottom right near the time to adjust the volume and check for mute.

Most likely there's a shortage with the microphone connection, or is gone. You can turn if off if you dont use it via the control panel. But if you use microphone quite often then you can buy an external mic off ebay or some place you like. They come in elegant designs as well and they are fairly cheap.

Hope this helps.

How do i get rid of feedbacks when i use my E6i Earset, am raning it through an AKG PT2000


Feedback is caused when a microphone's volume is returned out of the speakers, and then picked up again by the microphone causing a loop. The sound is amplified, picked up by the mic ,and then reamplified causing the feedback.
The first step is to make sure you are an adequate distance from the speakers. Also make sure the speakers are not behind you, but in front of you again allowing more distance and keeping the feedback down.
The most logical thing is turn the mic down to a lower level. Countrymans are very sensitive so adjusting the volume in small amounts will work too.
If all else fails, you may need to add an equalizer to your system if you do not have one. This will allow you to adjust out the frequencies that ring the most. The more sliders on an equalizer, the more adjustment you have. If you do have one already ,start from flat (all sliders straight across in the middle) and gradually inch up each slider individually until you hear the feedback ringing in the frequency it did before. You then slide the slider down below the middle to give you more volume before feedback. Don't go crazy here, and adjust only a few sliders down as needed. You will start losing overall volume in your sound system if too many are adjusted down.
Good Luck

My Mic is on all the time it is also coming through the speakers so when i turn external speakers on there is an huge feedback


See Adjust volume below



To use any microphone with your computer you will need to enable it in control panel. Instructions are for Windows XP but are similar for Vista and Win7


Click START, CONTROL PANEL, SOUNDS & AUDIO DEVICES



Click VOICE


In Sounds & Audio Devices Properties window locate SOUND PLAYBACK box. Click VOLUME button. Make sure that there is not a check-mark in the MUTE box against microphone in the list of devices and the volume slider is at the top of the scale.


Ensure the MUTE ALL box isn't checked before closing window.


Click VOLUME button in SOUND RECORDING BOX. Here SELECT microphone as an input source for recording (as opposed to un-checking mute in the playback controls).


NOTE if microphone is not listed in the 2 sets of volume controls click OPTIONS, PROPERTIES on the tool-bar and place a check against microphone in the list entitled 'show the following volume controls' and then click OK. The same applies to 'Internal MIC' if you are using a laptop with built in microphone - this must be enabled/ disabled separately to the external MIC.



To adjust audio volume.

Under VOLUME tab adjust Device Volume as necessary. Also (under Loudpeaker Settings) click Speaker Volume and adjust slider to suit.



You can also put a check mark in the box to show the volume control icon on the Task Bar so you can go straight to it to in future

My built in mic is not working properly,when I call somebody hear me but I don't hear him!


If the other person can hear you then YOUR microphone is working fine.
The reason may be that his microphone is faulty (solution below)
Otherwise:
  1. Make sure the volume is turned up on your speakers (and if using external speakers they are plugged in / turned on) . To increase volume go to Control Panel, Sounds & Audio Devices and adjust the slider on "Device Volume" . Also click on "Loudspeaker Volume" and adjust the sliders there as necessary.
  2. Can you hear other sounds (like playing music or videos)? If yes then you need to adjust the audio settings for your calling program (skype or whatever). Launch the appropriate program Click on Tools and ' test audio properties' on the program tool-bar. Follow the instructions on the screen.
  3. Try plugging in headphones and see if you can hear better on them.

NOTE if microphone is not listed in the 2 sets of volume controls click OPTIONS, PROPERTIES on the tool-bar and place a check against microphone in the list entitled 'show the following volume controls' and then click OK.


That should be it.

I skpe using my Asus, and my microphone does not work.The other party can't me...how do I solve this please


Hi

Are you sure that this laptop has a build in microphone? or are you using a external microphone?

in either case the most likely problem is that the skype sound settings on the input are wrong.

open skype, tools, options, then the audio settings page.
On the microphone, try all the possible options offered and see if it detects your voice, you can also try calling the skype test number / echo123.


a03a5d9.jpg
When you see the volume bar light up green like this as you speak or tap the microphone its working.

If you are using a external microphone, are you sure you have it on the right slot? Try the other plugs on the laptop and then go over the options again and see if you get sound.

You should also check from volume control that the microphone is not muted.

To check that open up start -> control panel -> sounds -> recording -> select the microphone and click properties -> check the levels tap and make sure its not muted and its turned up to full volume.

also some microphones have a on off switch on the wire, make sure its turned on.

By now you should be able to talk on skype.
Let me know if you need further assistance.
Thanks,
Ekse
