SOURCE: Dell Inspiron 6000 PC Audio Ports Damaged

You should have sound from the speakers at all times until headphones are plugged into the jack, the jack then overrides the speakers and allows you to listen using the headphones. If the speakers aren't working, it's because they're being overridden by the damaged jack. The only way to correct this is to replace the faulty jacks. You could get a set of external speakers, the con is they're bulky and inconvenient.

SOURCE: Microphone not working

Make sure the device is not muted in the audio properties of whatever software you are running. Most audio programs will allow you disable it.

You should be able to go to Sounds and Audio devices in the control panel to test. Under the voice tab is a button to test hardware. Check there as well.

Hope this helps.

SOURCE: speakers work but crackle when in use with my dell 8300

Most likely this is because of a loose socket. Check to see if there's any dust or debris inside the audio socket(s). If cleaning it/them out doesn't work, then the socket is loose and the only way to fix the problem would be to get the sound-card repaired or buy a new sound-card.

It's my opinion that buying a new sound-card would be cheaper. You can find a good amount of them at this website. Simply navigate to Computer Hardware>Input Devices. Now on the left click, "Sound Cards." Watch out, though. There's a link labeled, "Sound Card Accessories." However, it doesn't lead you to the same page.

Let me know if I can assist you further or if I need to explain anything mentioned above in more detail.

Trying to get my Labtec to work. Computer does not see it.


If you are taking the sound output from the green output socket on the back of your tower, then your speakers must be powered by a mains adapter.
You will have a black main adapter similar to a mobile phone charger, and the output from that on a thin wire will plug into one of your speakers, normally the one with the volume control on it.
To test if the speakers are powered up and working, plug an MP3 player into the green plug that goes to the speakers, does that play ok?

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.

How to connect it ?


Instructions
    • 1

      Place your mixer in a location that will allow you to hear the sound coming from the speakers clearly. The best placement is opposite the speakers, centered between the left and right pair. Connect the power supply to your mixer.

    • 2

      Connect the female end of an XLR cable to a microphone. Run the other end of the cable to your mixing board. Plug the male end into the "Mic" port of an open channel. These channels provide the preamps that will shape the sound characteristics of the microphone signal, processing them for output. Repeat the process for each microphone in your rig


    • 3

      Connect one end of a balanced 1/4-inch cable to the left channel jack labeled "L" found on the "Main Out" panel. Connect another cable to the right channel jack with the "R" label. Connect the opposite end of each cable to the matching left and right inputs on you amplifier.

    • 4

      Power on your mixer and amplifier. Test each microphone connected to the mixer for output.

    • 5

      Adjust the volume of each microphone channel to create a balanced mix. Use the "EQ" knobs to shape the tone and cut out frequencies that are causing squeal and feedback.

u have not described ur problem completely....i.e. the model or name of xpod speaker. and a speaker has only one lead and that is for output.however , if u have more than one leads that may be for microphone. the microphone lead end is pink (in some cases) and the speaker lead is green and it is the same colr for mic and speaker at the back of computer. simply play any media file in any media player and plug any of the lead in the green port at the back side of system unit(cpu).(if voice comes insert the other lead in pink port).otherwise insert the other lead in the green port and speaker will work

I am using pro tools 8 LE. I have a blue bluebird condenser microphone. the cable going into the mic is a male 3 pronged end. and the end going into my avid mbox mini is a normal ending (the ones that look...


The mbox mini is usb powered, wont work without power so your mac or pc must be powered on and connected. The blue led will be on when powered. Assuming you have the the appropriate cables, you want to make sure the condenser is plugged into the Mic/Line input. (Input 1 on the back of the mbox mini). All condenser mics require phantom power, so engage the +48V switch. Also make sure the DI (direct input) switch is not engaged. The input gain control is located on the front of the mbox... There needs to be speakers connected to the 1/4 output jacks on the back of the mbox or headphones on the front for sound output. Use the large knob for monitor volume control.
In protools: Create a Stereo Master fader track
Create a mono audio track
Set the input of the mono audio track to Mic/Line 1 Arm the track for record (click & make sure the R is red)
You should getting levels and sound output from your condenser.

How to i connect my bose companion 2speakers to my computer and get sound


hi, first Identify what computer you have. Is It A Mac or PC?

If it is PC
-------------
There should be 2 small 3.5mm coloured sockets on the back,front (or both ) of the main box (tower/desktop unit). You should find that they are coloured Green and Red. Green is for sound output (Headphones/speakers or hifi) and the Red is for sound input or Recording. Used for things like microphones. Some will accept line sources such as mixers and Ipods pr cassette players, but please check your sound manager, mixer settings in your opperating system to make your you have an adjustable input setting for Mic and Line input attenuation as not all do and you may end up with a distorted mess. You may also find there is a small diagram of headphones or a microphone to indicate sound "in" and "out" ports.

If you have a mac
-------------------------

Appart fom me being envious :-) there are two sockets. On laptop types, on the side or on the tower types on the front,back or both. They have a diagram of a microphone and headphones. Hadphones is for audio output to headphones, speakers, hifi, dj mixer. The Microphone is a sound input. Please read above for microphone port usage. Hopefully this answers your question. Please also bear in mind that if you have no sound once plugged in, you may need to adjust the audio properties in the system in the system and/or program you may be using

Yes, use balanced cable to the PA system and use a DI at the computer end.

The DI is known as a "direct box" or "direct input" and converts the UNBALANCED computer output to balanced to send toe the PA system.

Trying to use a microphone but not sure how to hook it up


No because the mic is a signel in device and the headphone jack is a signal out jack! meaning if you plug the mic into it the mic will act as a speaker and music will come out of it and ruin it!
I would buy an adapter at radio shack and plug it into the phono input on the back of unit! and if you dont have a phono input you will need to buy a small pre-amp and plug it into the aux or tape input!
That will work!
Please rate my answer!
Thank You!

Set-up wireless karaoke Mic.


I can't seem to find any technical details on the output specifications of the karaoke mic, but IF it outputs in consumer standard RCA format (a cable with two ends, one red and one white - often seen with a third yellow cable for video), then you should be able to plug it into the back of the receiver without trouble. Simply choose one of the audio connectors in the back to function as your microphone playback system - I suggest the DBS connector, unless you have a satellite system already plugged in.

Connect the Red RCA cable to the RIGHT channel port on your receiver and the White RCA cable to the LEFT channel (Red = Right). Now, select the DBS (or whatever port you plugged it into) using your receiver remote control. Hit the "ANALOG/DIGITAL" button on the remote until "ANALOG" mode is displayed.

If you want to connect the mics to a Karaoke system using the same receiver, simply unplug the White RCA cable from the Microphones, and plug in the White RCA cable from your karaoke device. Now, you'll get music playing from one side of the speakers, and mic playback from the other side, simulating the karaoke experience.

NOTE: If the microphones do not have a RCA plug on the back, please post a picture of the reverse of the Microphone receiver, and I will see what I can do to help you further.
