Polaroid Flatscreen no sound

What are you using that is muted?

I for 1 don't know. But try to go to www.Turtle Beach.com they can help you out. I have Turtle Beach Ear Force XC1 and my mic I can talk but I can't hear anything but if your mic isn't working properly try using a different controller. If that doesn't help try getting a brand new mic.

Are you sure you put it into the right hole I know i have two on my laptop so maybe try that

Troubleshooting Sound Issues Verify that the audio cable is connected to the AUDIO OUT or LINE OUT output on the Sound Card and plugged into the AUDIO IN or LINE IN of the Monitor.   Make sure there are no cables connected to the Headphone Jack (located next to the AUDIO IN port) on the monitor. If there is, please disconnect that cable and try the speakers again. Connecting a cable to the Headphone Jack disables the speakers. If there is no cable connected into the Headphone Jack, test a pair of headphones into that jack to see if you can hear sound out of the headphones. If you are able to hear sound out of the headphones, disconnect the headphones and try the speakers again.   Verify that the Mute on the monitor is not on or the Volume is not turned down.    Verify that the Mute on the computer is not on or the Volume is not turned down.<    If there is still no audio from the monitor's speakers, connect the Audio cable to another audio source like a portable CD player or tape player headphone output. If audio can be heard through the monitor's speakers, then there may be an issue with the computers sound card.    Connect another set of computer speakers (if available) or headphones to the AUDIO OUT or LINE OUT output on the Sound Card. If NO audio can be heard then there is an issue with the sound card. Verify with the computer's manufacturer for additional assistance.   LCD TVs Troubleshooting No Sound from a LCD TV No Sound when using RGB (when connected to a PC) Confirm the audio cable is plugged into the Audio in on the LCD TV and the audio out on the computer. Note: On the N1700W use the GREEN mini-jack; on this model Audio is SHARED between DVI and RGB, there is only 1 audio channel for data connections. The N1700w is designed to take a 1.0v RMS audio signal for optimal sound quality.   Confirm that both the LCD TV Mute and Windows Mute are off. A general message will be displayed on screen to indicate status of Mute (On or Off).   Press the Volume Up Button on the monitor or remote to confirm the Volume is not set to zero.   Confirm that PC volume is sufficient by using Windows/Macintosh Volume adjustment settings.   Try plugging another audio source such as a CD or Cassette Player directly into the Audio port on the LCD TV to confirm the speakers work, or try plugging headphones or external speakers into the sound card on the Computer. If the Headphones or External Speakers do not work, contact the manufacturer of your Computer for further support. No Sound when using S-Video/Composite/ Component Video Confirm the audio cable is plugged into the Audio in on the LCD TV and the audio out on the S-Video, Composite, or Component Video device.   Confirm Mute is off. A general message will be displayed on screen to indicate status of Mute (On or Off).   Press the Volume Up Button on the LCD TV or Remote to confirm the Volume is not set to zero.   Try plugging headphones or external speakers into the audio port on the S-Video, Composite, or Component Video device. If the Headphones or External Speakers do not work, contact the manufacturer of your S-Video, Composite, or Component Video device.   Note: Some ViewSonic monitors do not include speakers.

The biggest thing woul be check your sound settings on your comptuer and make sure its not muted. also if thier is a switch on the headphone make sure they arnt muted,
to check your comptuers volume settings, look for a speaker phone down by your start menu, or go to your control panel, look for anything that has to do with sound. open that open, and just make sure the mic isnt muted,

that is what is happening to me and alot of people are starting to mute me and remove me of their friends list and i dont no how to stop it!

Give them the model number of your television and the problem you are having with the use of the headphones. I hope this information helps you solve your problem. How do I get headphones to work with my TV? o Connect the headphone cable to the headphone jack on the side of your TV. o The sound will be heard through both the headphones and on the TV speakers. o Press Mute to hear sound only through the headphones. o Use the volume buttons on the remote to adjust the volume level. o You must remember to press mute again to hear sound through speakers. It will not automatically come on when you unplug the headphones.

sounds (pun intended) like you have your headphones plugged into the microphone input. See if you can change the spot they are plugged in...

good luck

if you are able to hear normally from the speakers and not from the headphones possible reasons could be:
the audio is muted or very low
there is a mute switch on the headphone that is turned on
the headphone is not firmly plugged in or is in the wrong site eg microphone
hope it helps
please inform if it helps..
