I have a sound problem with my HP Pavilion dv6t-7000 CTO Entertainment Notebook PC

It was working properly but for some reasons it is not working I reinstall the IDT Codec driver but nothing happen
What should I do in this case

Hi,
Right click the speaker icon in the Taskbar and select Playback Devices.  Left click 'Speakers and Headphones' once to highlight it and then click the Set Default button - check if you now have audio.
If you still have no audio, open windows Control Panel, open Administrative Tools and open Services.  Check that the following services are all showing as Status= Started and Start-up Type= Automatic
Audio Service
Multimedia Class Scheduler
Windows Audio
Windows Audio Endpoint Builder
If you need to make a change to any of the above, just right click the service and select Properties, then in the dropdown box next to 'Start-up type',  select Automatic and click Apply to save the change.  Then click the Start button.
If you still have no audio, open windows Control Panel, open Device Manager and open up Sound, Video and Game Controllers.  Right click the IDT device, select Properties and click the Drivers tab - is there any error code showing in the 'Device status' box?
Regards,
DP-K

  • Hi. I have a sound problem with my "New" Ipad.

    It has happened five times now that no sound is working on the Ipad. It is not on mute, and the volume is full on, but there is no sound. However, by restarting the Ipad I get sound again. I don´t know what to do about it. Should I go back to the store with it? Has anyone else had this problem?

    Try this  - Reset the iPad by holding down on the Sleep and Home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider - let go of the buttons. (This is equivalent to rebooting your computer.)

    Hi,
    Uninstall the current driver for the IDT audio.
    Resource:
    Uninstalling Software in Windows 7
    Uninstall or change a program in Windows 7
    Install the latest IDT audio driver for your model from here.
    Restart the system and check the result.

  • Really weird sound problem with rhythmbox[SOLVED]

    Well, I can't find anything on this, so i'm posting it here. I have no sound problems with alsa or other gstreamer apps(totem, banshee plays sound just fine). But when I try to play something in rhythmbox it just does not work. Mostly there is no sound, but every couple of seconds you can hear a distorted sound that is suposed to be playing for a moment. Rhythmbox does not issue any warnings or errors when launched from terminal. Is this some kind of bug?

    I had the same problem, but it disappeared yesterday. Try it run under root - it helped me. I dont really know how i fixed it, but it works under normal user now as well ...I hope there will be someone who knows.

  • I have sounds problems with iOS 7

    I have sounds problems with iOS 7. I can not hear my music, all the apps have no sounds. Only when I ask Siri has sound but it's too loud and awful. I found 2 errors with I ask to Siri what things she can do in Spanish the is an error and one word or If I ask who am I? She said that I have to go to settings and indicate her who I am but I already have that configured. And I try to configure again just in case, I do the same question and she still doesn't who I am.

    Try a Restart. 
    Press and hold the Sleep/Wake button for a few seconds until the red "slide to power off" slider appears, and then slide the slider. Press and hold the Sleep/Wake button until the Apple logo appears.
     Resetting your settings
    You can also try resetting all settings. Settings>General>Reset>Reset All Settings. You will have to enter all of your device settings again.... All of the settings in the settings app will have to be re-entered. You won't lose any data, but it takes time to enter all of the settings again.
    Resetting your device
    Press and hold the Sleep/Wake button and the Home button together for at least ten seconds, until the Apple logo appears. Apple recommends this only if you are unable to restart it.
    Or if this doesn't work and nobody else on the blog doesn't have a better idea you can contact Apple. 
    Here is a link to their contacts with most of the information below.

  • Hdmi sound problems with m9150f in media center

    I am running a pavilion m9150f Q6600 vista 32 bit and GeForce 8500 gt graphics on a sony wega 55" lcd projection tv. Recently I have been having problems with media center sound. Recorded programs from standard channels (2-64) seem fine but hd channels (1341, for example) produce an error message stating "Unsupported Audio Signal. Please check device output." Which kills all sound from Pc. After shuffling through various output options, often returning to the original settings, and occasionally reinstalling devices or drivers, the problem is fixed. Then, seemingly at random, POOF!, error occurs again.I am at my wits end and am ready to throw my PC out in the street and hit it with a bus! Please help prevent its untimely demise.
     Thank you.

    Hi again
    I have downloaded the Realtek sound driver from the Tosh page and unzipped it.
    (I have chosen the driver for Vista!!! I suppose you use Vista???)
    There is a folder called sound. Access this folder and run Setup.exe
    But before you will start this procedure you could access the device manager (control panel -> computer -> device manager) and choose sound, video, and game controller. There you have to mark realtek AC and click on uninstall and reboot the unit.
    After this sound driver removing you should start the new driver installation described above. (setup.exe)

  • I have been having problems with my speaker. After the recent update I am unable to listen to movies or music using my speaker. The volume bar is completely missing. If I plug a headset into the port, the volume bar reappears.

    I have been having problems with my speaker. After the recent update I am unable to listen to movies, music or apps using my speaker. The volume bar is completely missing. If I plug a headset into the port, the volume bar reappears and then disappears after the headset is removed. This is quite annoying. My child's Apps that he likes to play will not even make a sound. HELP!!!

    Do a reset (Hold Sleep/Wake and Home buttons about 10 secs or more till Apple logo appears, ignore the Slide to Power Off that appears)
    Note: You will not lose any data.

  • Is there a fix yet for the no sound problem with lion on the iMac without having to restart every time I switch the computer on?

    Is there a fix yet for the no sound problem with lion on the iMac without having to restart every time I switch the computer on?

    Try booting in Safe Mode by holding the the shift key immediately after powering on your system. Safe boot mode will for a directory check of your startup volume, then load only the required kernal extensions (kext files), and deletes some cache files. Once the system boots into Safe Mode you can simply restart the system to see whether the issue has been resolved.
    If you still have the issue try resetting the SMC by shutting down the system and disconnecting the power cord for ~15 seconds, then reconnecting the power cord. Next, reset the parameter RAM (PRAM) by holding down the option-option-P-R keys after powering ON the system. Wait until the iMac restarts twice, then let the system boot normally.

  • Sound problems with iphone4s,

    Hi, I have a 4s and lately I have had many problems with the speaker, q only hear it when there is an incoming call or message, when I adjust the volume from settings / sounds but when you play a video on youtube or whatsaap alerts, not hear anything unless you have the headphones on, and I've read some post and I cleaned the port with toothbrush, alcohol, I restored, I dried with a hair dryer, I've put in a full day off ,, I have done everything and nothing works, only when you clean with alcohol and a toothbrush works for about 3 or 4 minutes but then fell silent again! I do not know what to do, I'm desperate, any of you have any advice?, should i change the charge port?,,,,thank you very much for your time.

  • Sound Problems with USB Soundcard

    Hi,
    i have some problems with my Terratek USB Soundcard. I use it for Teamspeak 3 and Skype. After a while the sound is going verry crappy and robotic. After that, i have to close all apps wich are using this soundcard and then everythings ok for the next aprox 20 minutes.
    Two friends have the same problem with a Hama USB Soundcard. I think this is a Snow Leo problem.
    Would be nice to have a solution...
    I tested on my MacMini and my Macbook Pro.

  • Sound problems with my Visio

    Hi, I have read that people are having sound problems with their Vision M players, hissing etc.
    I wonder if anyone has had the problem I have - I cannot alter the volume! When I plug in either headphones or portable speakers into the M, using the touch pad has no effect on the volume. If I unplug it the touch pad then alters (or appears to) the volume - judging by the scale on the right of the screen. Plug the phones back in again and I get the same one level of volume.
    Also, the screen goes blank when I plug in phones or speakers.
    I am an MP3 player virgin and have no idea if the fault is mine or not.
    I bought my Vision M from Amazon, who very quickly sent me a replacement when I contacted them - even before I had returned the original. But the replacement has the same problems.
    Any comments would be welcome.
    John

    woggydog, thats what happens when your plugging outputs into the Audio/Video out socket of the player using the dock or supplied connector... it goes into line Out Mode, which cuts out audio from changing since the amplifier would be able to control this on a sound system.
    The one that shouldn't do this is the one on the top right of the player.

  • Sound problems with Portege M600 using WXP SP3

    I have had on-going sound problems with my laptop and feel so frustrated - please help!
    I have downloaded the sound driver (abt a million times - and tried uninstalling then reinstalling) - and repeatedly get no volume icon on the desk top and a message saying "no sound driver can be found".
    I did manage to fix it once - when i had WIndows Vista installed - by finding some obscure patch - but this time around - no solutions.
    Can anyone help - it is so frustrating!!!!

    The mentioned patches are part of Win XP SP2 & SP3
    So ensure that all service packs are installed.
    Then go to device manager and delete the High Definition Audio Controller (in system devices) and additionally delete all devices from Audio, Video and Game controller section.
    Then reboot the notebook.
    Wait until the device would be recognized again and then install the sound driver!

  • Sound problems with Satellite A100 (PSAA8)

    I am continually having sound problems with the laptop. Whilst I hear the windows start up noise and beeps, I cannot hear any sound from things like CDs, iTunes, Media Player - in fact an error message will always come up. In Media Player the error message "Windows Media Player cannot play the file because there is a problem with your sound device......." comes up. I have a the standard pre-installed Realtek sound thing on my laptop. I have tried downloading a newer driver from the Toshiba support centre, but I don't know what to do with the zip file. Also in Control Panel, Sounds, everything is greyed-out.
    Hope someone can help cos I am going nuts with this :-)
    Thanks
