HP Pavilion m7-1015dx Entertainment Notebook PC: Lack of sound

My laptop suddenly stopped playing audio! I first realized it when I tried to watch a video on YouTube, but I went to FaceBook and watched a video, where I was able to hear sound. 
I have tried uninstalling and reinstalling the driver from the HP website and have gone through SETTINGS and the CONTROL PANEL to make sure everything is set up. I am quite frustrated at this point, plus I just realized my warrenty is out as well, so this is my last hope! Bummer...
All help is welcome!

Hi Trot2it,
From the sounds of it you are having a problem that others are also experiencing with a Windows 8 Update causing audio issues.  There is a workaround for this issue but before you get to that I have some audio troubleshooting for you to try.
The first thing to try is this HP support document No Sound from Speakers. It has a number of good troubleshooting steps including using the built-in Windows troubleshooter.
Another solution is to uninstall the driver manually then force Windows to reinstall it. Follow the steps below to do that.
Step 1: Open Device Manager and open Sound, video and game controller section.
Step 2: Right click on your audio driver and select Uninstall.
Step 3: Restart the computer. Windows will then force in the driver on startup.
The last troubleshooting step is to try creating a new user account to see if the issue is only affecting the one account. This can happen is something has been corrupted in the one user profile. This HP support document Managing User Accounts and Logins look under the section Creating a new account in Windows 8.
Here is the workaround for the Windows Update:
At this point, unless you want to reinstall the operating system, the only other option is to tackle the update, KB2962407.
Uninstalling the Windows Update, then hiding it, is the only method of eliminating the issue if it caused by this update. Here is the procedure for uninstalling the update:
Step 1. Go into Control Panel, then click on “Programs and Features”.
Step 2. Click on “View Installed Updates”. Look for the update with the ID number KB2962407.
Step 3. Right-click on the update and select “Uninstall”. Restart the computer.
Next, here is the procedure for hiding the update:
Step 1. Go into Control Panel, then click on “Windows Updates”.
Step 2. Click on “Check for Updates”. When the process is completed, is should find important update(s) available. Clicking on the message will open a window where the important update(s) is.
Step 3. Right-click on the KB2962407 update and select “Hide Update”. This will prevent the update from being installed next time Windows Updates are being installed.

  • Power supply for HP Pavilion m7-1015dx Entertainment Notebook PC

    I have a HP Pavilion m7-1015dx Entertainment Notebook PC.
    The power supply (AC adaptor) that it comes with is HP part number 608428-002.
    I also have a different power supply (AC adaptor) that came with a much older HP Pavilion notebook.  This older power supply is HP part number 519329-003.
    Is the HP Pavilion m7-1015dx compatible with the older power supply (part number 519329-003)?
    Thanks!
    Mike

    519329-003 is definitely the right part number.  I just double-checked, and that's what's written on the hardware.   If you do a google search for "hp part 519329-003", you get a ton of results.
    The older HP notebook has another power supply, with HP part number 608428‑002 608428‑002 608428‑002 608428-002.  So I know that 608428-002 and 519329-003 are equivalent.
    Is the newer notebook (the HP Pavilion m7-1015dx) compatible with the power supply that has HP part number 608428-002?

  • HP Pavilion m7-1015dx Entertainment Notebook Wi Fi issue

    Greetings:
    I went to the software and Driver Download page to update the adapter (RAlink RT5390R 802.11b/g/n 1x1 Wi-Fi Adapter) since I  updated my laptop to Windows 8.  After re-starting the computer, WiFi shows as off.  I  tried to uninstall and re-install the driver and it does not work.  I don't know if the driver is working wit W8, but it is annoying as I have to only use the wired access  from the wall instead of the wireless connection.  Also, the driver  for Windows 7 when the O/S was previously installed worked flawlessly.
    Please help.

    YEs - they are greyed out, but did you see anything in the BIOS that indicated that the Basic IO recognized your wireless card. You can't select the WLAN FCC ID - but it is an indication that the IO is recognizing the mini wireless LAn card. IF your IO recognized wireless then you know it has something to do with Windows 8 compatiblity or drivers. ALso, are you sure you got the right driver.. there are seven wireless drivers available for your model: http://h10025.www1.hp.com/ewfrf/wc/softwareCategory?os=4132&lc=en&cc=us&dlc=en&sw_lang=&product=5273...

  • Can i change graphic settings on a "HP Pavilion dv6-3161eo Entertainment notebook pc"?

    Hi
    I have a "HP Pavilion dv6-3161eo Entertainment notebook pc" and I run Windows 7 64-bit. Lately I bought a lot of games, and I was hoping to play them without any problems. I have been able to before, so nothing should get in my way for doing it now. But it seems that my graphic settings keep changing from time to time, since when I play, I get a lot of lagg, both online and offline. Sometimes I can play the games without any lagg, but the most times the games lagg when I play them. The times when I can play without any problems, I can also watch HD movies online, which I can't when i can't play the games without lagg. To make an example, I bought a game called "Elder Scrolls V: Skyrim". When the game starts up, it automatically "Detect your video hardware and set video options accordingly". The most times when I start up the game, it sets the video quality to "low quality", but sometimes it sets the video quality to "high quality". Those times, I can also play the other games without lagg. I am almost sure, it is because my graphic settings on the pc are being changed, but I dont know how, or how to do it manually. So is it possible to solve this problem and/or change the graphic settings manually?

    You might have too many things running on the pc, such as browsers, music players, downloaders as you load the game which would explain the erratic behavior of the game checking your available settings.
    PS, Skyrim Rocks, as does MW3

  • Sound Issues HP Pavilion dv6-6158nr Entertainment Notebook PC

    Hello,
     I have HP Pavilion dv6-6158nr Entertainment Notebook PC with Windows 7 Pro 64-bit OS. Recently I noticed issues with how my volume control works. I am not sure if it's an application issue (Firefox 9/10) or audio drivers. While watching playing an audio file or watching video my default playback device is set to speaker, but as soon as I plugin my headphones both headphones and speakers will go to mute. Some times disabling and re-enabling the device will solve this issue, and other than that I also have to restart Firefox to get the sound back.
     Tried installing all the available updates form windows, also reinstalled/update the sound drivers as n admin with no possible fix. Also as shown in picture below, when I try to make a Google call using Firefox I use built-in mike an headphones. During that time headphones icon will be appeared in the window shown below listed as communication device and disable both audio in/out.
    Let me know if any further information is required.
    Thanks.

    First uninstall the audio driver:
    Click Start and type device in the search field, then select Device Manager. >> Audio, video and game controlar >> right click and uninstall all values under it >> restart >> download and install the following drivers:
    BIOS
    Audio

  • HP Pavilion dm1-4000au Entertainment Notebook PC_Keyboard and Touchpad Suddenly Stops Working

    Hi there,
    I have an HP Pavilion dm1-4000au Entertainment Notebook PC (QG411PA) running Windows 7 Ultimate 32-bit for more than a couple of years already. During those times up until now, whenever my laptop is on standby for an hour or so, its keyboard and touchpad suddenly stops working, regardless if its running on battery or on AC power.
    I always ensure that I have an external mouse in order for me to navigate properly and pull up the on-screen keyboard in order to type once that issue arises.
    All appears to be updated in terms of Windows Updates and I even reformatted it, but issue still persists.
    Is this particular issue that I am experiencing a harware issue? Perhaps a software issue? Or maybe a defective model itself?
    Your prompt response is highly appreciated.
    Sincerely,
    Led

  • USB 3.0 Upgrade for HP Pavilion dv9700 CTO Entertainment Notebook PC

    Is it possible to upgrade my HP Pavilion dv9700 CTO Entertainment Notebook PC to USB 3.0?  I've been searching the website and google and haven't found any concrete answers just yet.  I'd rather not have to buy a new laptop just to get USB 3.0.  It's been the most reliable pc I've ever had and I don't wantn to replace it!
    Thanks,
    Paul

    Hi,
    You have to buy a new laptop or swap the system/motherboard or buy an Express card - USB 3 (I've got one) or PC card - USB 3. For desktop , this is much simpler, a PCI - USB 3 card will do.

  • Pavilion dv6-3227cl entertainment notebook powers on but only has a black screen

    An HP Pavilion DV6-3227cl Entertainment Notebook, that is approximately 2 years old and is running Windows 7 Home Premium, AMD Vision Premium, will power on but not boot up.  The fan runs and the "caps lock" light flashes once approximately every 4 seconds but all I get is a black screen with no cursor or error messages.  There are no beeps.  The power supply indicator illuminates (white) for about a second, then turns to a dim orange when the battery is installed, but remains white when the battery is removed.  However, the two indicator lights (I'm not sure what they are for) next to the USB port nearest the power indicator light illuminate as follows:  the one on the left (as you are looking at the right side of the notebook) is white; the one on the right is orange.  Both are fully illuminated (not dimly as the power indicator light).  The power indicator light is not as bright as the other white indicator near the USB port.  The notebook has booted up and appeared to be running one time since having this problem started, but I have not been able to get it to boot up again.  I am told the battery is bad (it's my brother in law's notebook), but is it possible the problem is with the power source rather than the processor or motherboard?  I appreciate your comments/advice on this matter.  Thank you.

    Hi fejevitzky,
    Your question, "Based upon that, I believe you are telling me you do not think it is the BIOS--is that correct?" Yes, as long as you dont see any "white" light reveal from LCD bezel back side while with blank screen state. LCD bezel is the cover around LCD, most design put LED modeule at the bottom side next to LCD. While back light is not on during boot up sequence, that means system doesnt have chance to get BIOS program running. It also means, it stuck at state of hardware bring up. Normally motherboard related.

There is no HDMI audio device listed on the computer. Audo devices that are listed are: IDT High Definition Audio CODEC for speakers and headphones.

    Hi,
    My suggestion:
    Go to this site to download the required driver.
    Totally uninstall the Audio driver.
    Install driver from the downloaded file.
    Turn off the TV and laptop.
    Connect HDMI cable.
    Turn ON the TV first.
    Turn ON the laptop.
    Regards

    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/sp41501-42000/sp41698.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,download and reinstall the Chipset driver on the link below.
    Chipset Driver - Windows Vista.
    When the reinstallation has completed, shut down the notebook, unplug the AC Adapter and then remove the battery.  Hold down the Power button for 30 seconds.  Re-insert the battery and plug in the AC Adapter.
    Tap away at the esc key as you start the notebook to launch the Start-up Menu and then select f10 to enter the bios menu.  Press f5 to load the defaults ( this is sometimes f9, but the menu at the bottom will show the correct key ), use the arrow keys to select 'Yes' and hit enter.  Press f10 to save the setting and again use the arrow keys to select 'Yes' and hit enter.
    Let Windows fully load - it will automatically load an audio driver, but just let this complete.  Then open your Downloads folder, right click on the IDT installer and select 'Run as Administrator' to start the installation.  When this has completed, 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.

  • Bluetooth on HP Pavilion dv7-2173cl Entertainment Notebook PC

    I can't seem to make this work with my Droid Razr Maxx or bluetooth wireless speaker even though there are icons in Devices and Printers dialog box with little yellow triangles on them.  Ever since I have owned this laptop, I have not been able to use bluetooth.   I have a 2009 HP Pavilion dv7-2173cl Entertainment Notebook PC that is running windows 7 all updated. Device manager shows that there is a bluetooth module to which I have uninstalled and reinstalled many times. I'm beginning to think that the module is defective. 
    This question was solved.

    It appears that the device is an HP branded bluetooth module.  However, the information I can locate says it is powered by a Broadcom driver.  
    Did this notebook originally come with Windows 8?
