Could you post more preliminary info as to the problem. Did it just go out? Did you do a restore or reload the system because of a problem? Did you add new hardware? Has this happened before or is it reoccuring?

I wanna connect my laptop(lenovo G450) to samsung series 4 lcd through hdmi cable


Hello,

A HDMI cable can output both audio and video, whilst some computer with Windows XP cannot automatically switch to HD Audio output as Windows 7 can. Thus manual setup can solve the problem.

After connecting the HDMI cable, Go to "Start" > "Control Panel" > "Sounds and Audio Devices", double-click "Sounds and Audio Devices. Select "Audio" tab on "Sounds and Audio Devices Properties" window.

On "Sound playback", change "Default device" from "Conexant HD Audio output" to "NVDIA High Definition Audio".

Your television should have several HDMI ports, select the appropriate HDMI port number and check if TV is not muted.


Hope this helps.

Acer aspire net book audio is warbled


When trying to isolate and diagnose the specific cause of any computer fault, think back to when the computer was working normally and then list any hardware, software or settings changes between that time and when the fault you are experiencing first appeared.

Sound/Audio problems are often caused by simple settings errors. Before trying anything else, think if you have connected any new device or installed or used any new software on the computer that is Sound/Audio-related (such as a cellphone, an MP3/MP4/MP5 player, a bluetooth device, a microphone, a Voice Over Internet Protocol [VOIP] Headset or multiplexing device, a dial-up modem or dial-up modem based transaction or stock keeping or postal franking device, a multimedia player, a speech recognition program, media playing software, fax/phone software, etc., etc. Any of these sorts of devices or software are capable of changing a computer's default Sound/Audio settings.


Reset the Sound/Audio to the correct default device - start -> control panel -> sounds speech and audio devices/hardware and sounds -> audio -> select main audio on-board chip or sound card from the Playback Device drop down menu or the panel of different device options -> apply -> OK -> restart computer.


Quite often nothing more needs to be done to restore Sound/Audio that was disabled by settings changes or errors.



If none of the above suggestions solves the problem, then the cause might be a possible Sound/Audio Driver conflict, corruption or file deletion issue.
Uninstall all components of the installed Sound/Audio Driver from Add or Remove Programs/ Uninstall a Program or its equivalent in your Operating System - > restart the computer -> reinstall the Sound/Audio Driver from the Drivers and Utilities Installation Disc or download, save (so as to create and keep on the computer the Sound/Audio Driver Setup Files in case of future Sound/Audio Driver problems) and install it from the Support and Download pages of the Acer website -> restart the computer.


The Sound/Audio Driver for this model can be downloaded from here once you enter your precise Model Number (usually to be found on a label on the underside of the netbook) :

The pivotal action in trying to isolate and diagnose the specific cause of any computer fault is to think back to when the computer was working normally and then list any hardware, software or settings changes between that time and when the fault you are experiencing first appeared.

Audio problems are often simple settings problems. Before you try anything else think if you have connected any new device or installed or used any new software on the computer that is Audio-related (such as a cellphone, an MP3/MP4/MP5 player, a bluetooth device, a microphone, a Voice Over Internet Protocol [VOIP] Headset or multiplexing device, a dial-up modem or dial-up modem based transaction or stock keeping or postal franking device, a multimedia player, a speech recognition program, media playing software, fax/phone software, etc., etc. Any of these sorts of devices or software are capable of changing a computer's default audio settings.

Often this is all that needs to be done to restore audio that has been disabled by settings changes.



If not then turn your mind to a possible Audio/sound Driver conflict, corruption or deletion.
Uninstall all components of the installed Audio/Sound Driver from Add or Remove Programs/ Uninstall a Program or its equivalent in your Operating System - > restart the computer -> reinstall the Audio/Sound Driver from the Drivers and Utilities Installation Disc or download, save (so as to create and keep on the computer the Sound/Audio Driver Setup Files in case of future Sound/Audio Driver problems) and install it from the Support and Download pages of the Acer website -> restart the computer.

The sound has stopped working on my Dell Inspiron 700m. Have checked the Sound and Audio Devices in my Computer but all looks ok!


Hi andrewc489

DELL INSPIRON 700M NOTEBOOK PC AUDIO PROBLEM

You don't say which Operating System you use, so my answer will be presented in general, Windows terms. If yours is a non-Windows Operating System, consider applying the logic and principles involved here to your own Operating System and, if in doubt, please feel free to add a Comment or Clarification to this Question.

Make sure the Audio function in BIOS is 'Enabled' and then save those new BIOS settings.

To enter BIOS Setup, Press 'F2' or 'Del' during the first POST Screen at Start Up.

Also, check the status of the Audio Device and the Audio Driver in Device Manager.

Start > (My) Computer > (System Properties) View System Settings > Device Manager

This will tell you if the Audio/Sound Device is installed and functioning properly and if the Audio/Sound Driver is installed properly. If a red 'x' or a yellow question or exclamation mark appears next to the Audio/Sound Device, then there is probably a settings anomaly, fault, error or conflict with the Audio Device and/or its Driver.

AUDIO DEVICE SETTINGS

For your Audio/Sound Device to function properly, it must be set as the Default Device:

Start > Control Panel > (Hardware and Sound) Sounds Speech and Audio Devices > Sounds and Audio Devices > (Manage Audio Devices) Audio > click on the Drop Down Menu to the right of "Sound Playback - Default Device" (preferred Default Playback Device) > select "Sigmatel STAC 9750 AC97" > Apply > OK > Restart computer.

AUDIO/SOUND DRIVER PROBLEMS

Re-install the correct Audio/Sound Driver that relates to both the Audio/Sound Device (SIGMATEL STAC 9750 AC97) and your Operating System, then restart the computer. Install the Audio/Sound Driver either from the motherboard's Drivers and Utilities CD or from here:

http://support.dell.com/support/downloads/driverslist.aspx?c=us&cs=19&l=en&s=dhs&ServiceTag=&SystemID=INS_PNT_PM_700M&os=WW1&osl=en&catid=&impid=

If your Operating System is not the original Windows XP for which this Notebook was designed, then it is highly probable that no Audio/Sound Driver exists for that Operating System.

If you are committed to both this Notebook and an unsupported Operating System but all the other Devices and their Drivers are functioning normally except the Audio Device or you are using XP but the Audio/Sound Problem remains unsolvable (faulty Audio/Sound Chip), then consider buying and installing an external USB Sound Card that is pre-confirmed as being compatible with your Operating System. They are inexpensive. See example:

http://www.amazon.com/s/ref=nb_sb_noss?url=search-alias%3Daps&field-keywords=xternal+usb+soundcard&x=16&y=23

I hope this helps.

Just bought HDMI cable to be used on dv9700 got the picture on my tv, but no sound go to sound option but not able to see any HDMI sound output I got only 2 options on my sounds: 1. Speaker 2....


We might need to change the audio settings from Sound and Audio device properties window.

Open Control and double click on Sounds and Audio devices to access the window.

Change the audio output from analog to digital.

Make sure that HDMI audio is enabled in the sound device.

If the source device menu has adjustment for PCM frequency, set the frequency to 96khz or less than that.
