HP Probook 455 G1 dts+ audio software & mute button light change missing on Windows 10

Dear Support! I upgraded my probook from win 8.1 to win 10 home and i have a few problems in relation with the audio. 1. In win 8.1 the audio driver has a dts+ software (if i remember good for the name) which can optimize the sound with effects and eq etc. The notebook sounds good with this but in windows 10 i can get this and the quality of the sound is much worse. In addition in the device manager on win 8.1 the audio card names as IDT High Definiton audio but in win 10 it is "High Definition Audio Device". I don't know whethet that matters. (also has an amd high definition audio device, but if i know good its the hdmi audio) So I want to ask how can i get this to win10. 2. The audio mute button in win 10 doesnt change color -the wifi button does it- from white to orange if there is a change. The funcionality is working so it mutes the sound. So i would like to get some solutions about that, i tried to download drivers from hp support but i didnt see anything for this. Thank you for your answers, Akos ConfigHP Probook 455 G1 with AMD A10-5750M APU

Everything i need is the driver from the win 8.1, i can't believe nobody from HP can help me in this.......

  • Volume buttons and mute button don't function in Windows 8 64-bit

    Almost funny, I also have installed Windows 8 64-bit on my ThionkPad SL500 (clean install). I have read other people complaining about "Volume buttons and mute button don't function". This is exactly the same problem I have. I have found no exact procedure about what software to install to make this work. Instead people refer to other threads that often end in some desert... So, does anyone (Lenovo?) have a clear answer on what software to install (and links to those drivers please...) :-? And, yes, I have tried installing different software packages by following threads, but nothing has worked just yet... So, clear instructions / links, please :-)
    Thanks,
    Niels

    I recently found this information on the micorsoft troubleshooting website and thought of your post, not sure if you had found a solution but hopefully it is helpful.
    My keyboard volume controls suddenly stopped working
    If the volume controls on your keyboard stops working, check the Human Interface Device Access service on your computer to make sure it is set to Automatic.
    In the Start menu, type View local services.
    From the Search Results list, select View local services.
    In the Services dialog box, locate Human Interface Device Access. Make sure the status is set to “Started.”  If it is not started, click Start the service.
    Right-click Human Interface Device Access and select Properties.
    On the General tab, in the Startup type, select Automatic, and then click OK.

  • Mute Button Light Not Working, HP HDX 18t

    I just reloaded my HP HDX 18t series notebook and everything works flawless w/ Windows 7 Ultimate, but whenever I mute the system, the light does not turn red like it's supposed to.  Quick Launch buttons drivers are installed and everything.  What do I do to fix this?
    Also, it's red when I boot the PC, but when it loads Windows it goes to white and will not turn red.  Thank for the help.

    Same problem on my DV3T-2000 CTO after Vista to Windows 7 upgrade.  Updating IDT audio driver fixed it.  Windows Update and HP Support Assistant did not find that update, but HP Customer Care - Software & Driver Downloads did.

  • Elitebook 2540p Motherboard changed. Integrated motherboard IDT audio device missing in windows 7.

    Hi,
     Old situation:
    (I recently changed motherboard for my computer Elitebook 2540p. When i installed windows 7 to my computer the computer doesn't list any audio devices in device manager page. I've checked bios for any faulty settings and they are all set right. Theres no yellow marks in device list either and all drivers seems to be installed.)
    New situation:
    Installed windows 7 again and computer found / installed audio devices normally. I tested computer for hours to play audio from it and everything worked fine. I restarted computer several times / re installed battery to the computer. On one restart the computers audio quick mute button below the screen appeared to be orange and the sound speaker icon in windows was marked as X. I check device list again from device manager and there was no audio devices listed (No sound devices at all). After that i restarted computer and before the computer started downloadin windows i pressed the mute button and it turned blue. I then went to windows and sound devices / sound was working again.
     Old situation:
    I have motherboard integrated IDT audio device.
    When i try to install audio drivers from hp site for 2540p i get "Your system does not meet the minimum requirements for this update." And the device manager doesnt list any IDT audio devices.
     I then installed xp and the computer found IDT audio device normally and the sounds are working correct.
    New situation:
    After i did new windows 7 install and all my audio drivers installed / devices showed in device list / audio worked i downloaded audio drivers from HP driver site and installed them to the computer.
    Audio problems has not been occured again after my HP screen mute button turned to orange / Windows sound speaker was marked as X / Computer didn´t find any audio devices.
    Currently waiting if the problem occurs again and trying to think what would cause this ( Hardware problem or software)? And how to fix it permanently.
    Any help for this problem?
    BIOS is updated to newest version from HP driver download center.
    All windows drivers are installed.

    Hi,
    The functionality of the mute button is provided by the IDT Audio software so the problem may be that Windows 8 has installed a reference driver that does not contain this.  Often, the Windows 7 version works Ok, so I'd try downloading and installing the following IDT driver.
    http://ftp.hp.com/pub/softpaq/sp48501-49000/sp48830.exe
    After the installation has completed, restart the notebook.

  • HP Probook 4520s: sound card doesn't work (no sound, red mute button)

    Нello!
    I have an issue with my HP Probook 4520s. Its internal speakers  and microphone doesn't work. I've tried to install and reinstall drivers from here, tried to rollback driver to older version but I always have the same result: installed the IDT sound codec, and after a restart, the mute button  turned red and I cannot switch it.
    Soundcard device ID: HDAUDIO\FUNK_01&VEN_111&DEV_7605
    OS: Windows 7 Professional x86
    How can I fix it?

    Hi, just registered to post my solution. I got HP ProBook 4330s in for repair. Problem: some sticky liquid spilled all over and no sound. Also discovered that no microphone as well, but webcam did work just fine.
    What I tried:
    1) Installed fresh Win 7 Ultimate 32-bit and all official drivers (audio driver did not want to install), still no sound. Sound icon shows red cross. Message: No audio output device installed.
    1) Installed the newest version of BIOS, in my case F.40, still no sound.
    2) Pluged in headphones, still no sound.
    3) Took apart, unpluged and firmly inserted every possbile cable, still no sound.
    4) Found in BIOS everything that relates to Audio. Made sure Audio device is enable, still no sound.
    5) Install XP and installed XP sound driver, still no sound. In fact, that driver did not install correctly, showed some kind of error.
    What did work, in consecutive order:
    1) Took apart again and took out the coin battery that retains the BIOS data, date, clock etc.
    2) Put everything back together, switched on, entered the correct date in BIOS settings, and started Win 7 Ultimate. Still no sound. But I noticed that Win 7 Ultimate has found some devices and was installing drivers for it. Though did not check exactly which ones.
    3) If I could not get the sound working I was determined to buy some speakers with USB connection. Then, I remembered that I already had a set of speakers for another laptop. These speakers had USB connection to draw power from and a grean standard headphone connection/plug to draw audio signal. I plugged in these speakers into HP 4330s and the sound started coming from these external speakers. The sound icon next to the clock in bottom right corner switched to normal mode and I could control volume with my mouse. Then I unpluged external USB speakers and the sound started coming from the HP's built in speakers.
    Checked with Device Manager that correct sound drivers are installed and microhpone appeared to be installed as well. Though did not check with Skype if microhpone was working.
    I was soooo happy!!! I struggled with this problem for three long days, searched many forums (none gave solution), tried everything with drivers, took apart the laptop some three or four times (now I learned to do it with my eyes closed, so to speak).
    I started to think that taking out the BIOS/date coin battery did the trick. There must be some glitch in BIOS to motherboard connection in these HP ProBook laptops, and all BIOS settings need to be reset.
    I'll be happy if this helps someone.

  • When unlocked, pc automatically turns audio to mute.

    Hello, I have an hp Envy 15 j037el and after the windows 8.1 update happens that when the screen is locked and I unlock it with fingerprint or password, the pc automatically turns the audio to mute.
    Thanks in advance
    FV

    Hello @Archangel52210,
    I understand that you are having issues with your new computer running Windows 8.1 where the audio is muting automatically. I am providing you with an HP Support document: Using Recovery Manager to Restore Software and Drivers (Windows 8), which you can use to restore the original drivers that came with your computer. As these drivers and their settings worked I believe they will again and hopefully when they are updated next time hey take better.
    Please re-post if you require additional support. Thank you for posting on the HP Forums. Have a great day!

    Hi,
    Try the following.
    Download the IDT Audio installer on the link below and save it to your Downloads folder.
    http://ftp.hp.com/pub/softpaq/sp56501-57000/sp56717.exe
    When done, open windows Control Panel, open Device Manager and open up Sound, Video and Game Controllers.  Right click the IDT device and select Uninstall - you should also get a prompt to remove the current driver, tick the box to allow this and then proceed with the uninstall.
    When complete, restart the notebook and let Windows fully load.  Open your Downloads folder, right click on the IDT installer and select 'Run as Administrator' to start the installation.  When this has completed, restart the notebook again.
