Audio for internal speakers on HP620 lost

I lost the sound on my HP 620 laptop. In the control manager and device Audio everything seems perfect: drivers are visible and it is stated "this device works correctly. I can see the green bar in moving Volume control when I test audio, BUT nothing out of the internal speakers.

There are two features in Audio playback:

Speakers/headphones IDT High Definition Audio CODEC and

IDT High Definition Audio CODEC, headphones (real time data).

I tried to uninstall the device speakers/headphones, download the latest version of the driver from HP and install again, but no luck.

When I connect the computer to the TV via HDMI the sound works fine.

Now, the only big change I can think of is an update of the BIOS this HP Support Assistant made on June 2. Sound problems started before that.

I haver a HP 620 serial number: {deleted personal information}, product number: WT249EA #UUW, Vista 64-bit.

I hope someone can help, Mikael

Nice day.

It is for those who have trouble on HP speakres.

I have a problem that does not work my speakers, ut I have sound when I connect the headphones. I tried everything, reading on the web and encourages all solutions, but nothing happens.

Finally I just blow into the headset connector and use tootpick to clean the inside of the connector.

The inside of the connector, there is litlle relay. When the headphones are connectet who relay turning off the speakers and spend his helmet. So, if there is dust this relay can stay in closed mode and its cannot 'go' to the speakers.

So, I hope that Martin will help you with your problem!

I'm sorry if may gramm wasn't verry vell.

  • audio output lists only the internal speakers when usb is connected to the dac

    This problem happened after I had used my mbp for months as music server in a stereo system.  When I have the mbp connected via USB to an external digital to analog converter (dac), audio preferences had always listed the CAD.  Now it lists only the internal speakers.  I tried to reboot, checked my UBS cable, checked my dac.  The only thing I've done recently is to create a playlist and sync a new iPod to copy the playlist we.  I don't know if that could have anything to create the problem of lack of dac, but I am a relative novice on computers.

  • Re: Need internal speakers for Satellite A105

    I have a Satellite A105-S1013 laptop and need to replace the two internal speakers, which are slaughtered. Is there more than one distributor of parts to the United States I can contact?
    A Toshiba recommended charge $ 45, plus $10 shipping, which seems a bit much.

    Anyone knows of multiple sources?

    I recommend you ask the same question on Toshiba U.S. forum http://laptopforums.toshiba.com/tshb/
    Maybe the people of the United States know better where to find spare parts.

    By the way: check eBay US. With a little luck you can find speakers out there. I saw that many pieces for Toshiba laptops on eBay and you can get them for a few dollars only.

  • MacMini-digital server: only internal speakers?

    I've implemented a Macmini with digital music files to play through my stereo system with a remote ipad. But the mini will play only with internal speakers, even if it detects the CAD that I use.

    I tried selecting the DAC in the audio section of the mini, and I open the Apple Midi file. Once again, the mini is aware of the CAD, but even when it is selected, the Mini sends the sound for only its own internal speakers.  Unknown yet, when I 'speaker setup' and test to the left and to the right, the sound test IS sent to the stereo speakers. Frustrating!

    Any help much appreciated!

  • 23 - c010xt envy: internal speakers continue to work after plugging in the speakers external or headphones

    I got this computer for years with no problems. I use external speakers connected to the audio jack on the back. Once you plug in external speakers (or headphones), the internal speakers are disabled as expected.

    Last night my PC automatically installed the anniversary of Windows Update (update feature Windows 10, 1607 version). After this update, now my two internal speakers and external speakers are working at the same time! I can't turn off the internal speakers without also turning off my external speakers. The volume affects both sets of speakers as well. I tried to disable audio and re-clearance but that did not help.

    How can I go back to my original audio behavior where connect speakers external (or headphones) to the rear Socket 3.5 mm would automatically turn off the internal speakers? Thank you.

    Diameter of thank you!

    I couldn't select no other devices in reading or recording tab becuse it is said that they are "not connected". Update drivers, said that later I have already.

    But when I checked the other post, he fixed it! Now I get only audio speakers again... just like before and how it was supposed to be. Thanks again.

    Windows 10. So I did some research on a Microsoft support forum and I found this solution:

    • Access the device driver software manager - right click on IDT high definition audio CODEC - updated.
    • Choose "Browse my computer for driver software" - choose "Let Me pick from a list of drivers for devices on my computer.
    • Select "High Definition Audio Device" (not IDT high def...)  This is important) and click Next. You get a warning message but answer 'yes '.
    • Once windows have updated driver software, try to play the audio again and check.

  • Internal speakers on my HP ENVY TouchSmart all-in-One desktop PC 23-d027c no longer works

    Hello

    I just bought my HP ENVY 23-d027c TouchSmart all-in-One PC of office a few days ago.  It was working fine until I tested the speakers.  When you watch youtube videos, the internal speakers will stop working, while the mute button is not enabled.  It takes a few minutes, and then the speakers work again, only to cut out once more.  IT IS SO FRUSTRATING!  What's weirder, I put a dvd to see if it was the speakers, but the audio on the dvd seems to work very well.  Also, when I use headphones, the speakers work fine.  I don't know what the deal is, but according to my research, this seems to be a fairly common phenomenon on HP computers.  I'm struggling on the Exchange on this computer.  IF this isn't a simple solution, this machine will return to the store!

    Help, please!

    Thank you in advance!

    Hello MakCo,

    Your speakers are not working correctly.

    Go to Device Manager, uninstall the IDT audio and restart the computer.

    Uninstall it and reinstall the audio driver.

    Here is a link to the Device Manager.

    Do a hard reset.

    Turn off the computer.

    Remove the power cable and battery.

    Hold down the power button for 15 sec while booth energy sources are deleted.



    This should reset the hardware in the computer.

    That you put it on press the F10 key. This will load the BIOS setup utility.

    Press F9 to load the default values.

    Press F10 to save and exit.



    When the computer starts up, check if everything is working.

    I would like to know how everything goes

    Nice day.

    Hi thysgc,

    I think that it would be necessary to show a little more detail on your laptop, which model you have exactly?

    Normally if you connect external speakers, a window driver sound will pop up where you can choose between connected headphone or line out (external speakers), but both options will shut off the internal speakers.

    In any case, have you checked the Web from Toshiba site for the pilot of his most recent?
