Audio out doesn't work (i.e., like it is in eternal mute).

Sounds like you've muted your system, in-mute it per the owners manual's instructions or come back here if you can't find out through the manual!

Could just be a bad wire or the switch in the mic. It is hard to say without test equipment.

My windows is in french, so I might not translate the windows' names right, but i'll try to help you.
Maybe it's muted, check in your Configuration Panel, in "Sound and Audio", in the Volume Tab, click on the first "Advanced configurations". And check if it's muted.

You may have a dead meter.
Modulation is audio's affect on swing wattage or pep. Notice that needle moving more with your voice.
Dead key or carrier wattage is without your voice enhancing the power only with mic keyed.
I can only assume that the chipset you are referring to is an ic chip audio or pll which must be working if you are receiving audio.
Check your mic cord................ transmit and modulation and even your receive volume can be affected by the cord/mic plug solder joints or broken wires here.

the microphone might not need usb drivers to work
click start control panel sounds and audio devices select advanced there might be a tick in the mute box untick it or select audio from the microphone drop down list make sure you have the right one selected and in the volume box make sure the microphone box has a tick in it or select the voice tab and make sure that you have the right media selected also select volume make sure the box for microphone has a tick in it
hope this helps

1.

• Press the volume, the speaker icon at the bottom right of the screen showing WHERE TO and VIEW MAP

• On the volume screen there's a tick box for MUTE. If it's ticked press it and the tick will be removed. The satnav should then not be muted.

2. If this doesn't solve the problem it may be that the voice file is corrupted.

• Press TOOLS
• Press SETTINGS
• Press LANGUAGE

This brings you to a screen with VOICE, TEXT LANGUAGE and KEYBOARD
Press VOICE and select another English speaking voice. This may solve the problem.

3. If you don't have another English speaking voice;

• Download the latest version of Webupdater from http://www8.garmin.com/support/collection.jsp?product=999-99999-27 and install it to your computer
• Connect your satnav to your computer and run the Webupdater program
• Webupdater will find any software updates for your satnav. Install them. When the installation is complete it will find optional updates including voices. Select some English speaking voices and download them to your satnav.
• After you have disconnected your satnav from the computer you'll need to select a voice again as described in paragraph 2 above.
  

I assume you made sure that the mic is not on mute. Click on your audio icon and double check. If not I would update the chipset driver. I have attached a link to all the drivers for your Acer. Just select the correct version of Windows 7. Thanks for using FixYa

Hi phool0055 ,

There is nothing as a separate microphone driver that you need to install generally ,
All you need to do is check microphone settings , as to whether they have been changed or the microphone has been muted accidentally.

Please follow the below steps :-

• In control panel , open sound speech and audio devices
• The click on the audio , tab where you would find two options , sound playback and sound recording.
• Sound playback has to do with the sound that you hear , i.e. the headphone sound.
• Sound microphone has to do with the sound that you record or transmit i.e. microphone.
• Now you would have two options under sound recording sections, namely volume and advanced.
• Open the volume and advanced section and check if it has been muted.
• If it's muted , please unmute it and now you would be able to record your voice or chat using a microphone.

Hope this helps ..:)

If you have any functionality at all left to your touch screen, try to recalibrate it within the settings menu. Otherwise, remove the battery, wait about 15 seconds, then reinstall.

If that doesn't help, the touch-sensitive surface glass has gone out. Apparently, this component in the first-generation Eternity has chronic failures.

Replacing it is not too much trouble for an experienced cell phone technician. But, it's not for anyone who doesn't like to tinker with small things. Here's a video demonstrating the entire process: http://www.youtube.com/watch?v=QJpHHs9QM5U.
