No sound on my hp windows 7 64 bit

I lost the sound on my computer hp laptop

Most often when a device does not work, it is because the driver is damaged. Re-install a new copy should help

Remove the driver current completely and install the latest driver available.  For instructions on how to do read everything to update the drivers of my partner JMH3143 http://answers.microsoft.com/en-us/windows/wiki/windows_other-hardware/updating-a-driver/a5e6345e-af9b-4099-bef0-8d22254aa1c1?tm=1436753520149 here

  • No sound from HP - 8560p, windows 7 64 bit elitebook docking station

    I was issued a laptop Elitebook 8560p for use with a 90 W HP Docking station at work.  When the laptop is plugged into the docking station, the port ' audio out ' of the docking station does not work.  The sound continues to come out of the computer laptop speakers, or, if I plug the headphones into the headphone for laptop, it comes out of the helmet.  Plug the headphones into the Docking Station does not all the sounds (either of the two audio ports - in or out).  When the laptop is plugged into the docking station, no additional reading device does appear in the audio menu - just an output HDMI AMD (disabled) and speakers (activated).

    The speakers/headphones on the laptop works fine, the problem is just that the docking station is in no way "replica" or the audio output support and it's as if the port of the enclosure of the dock just weren't there.  So, I could use my headset by plugging directly to the laptop, but this really seems to defeat the whole concept of a docking station.  All other ports (video, usb) seem to work on the docking station.

    I am running Windows 7, 64-bit.

    I reinstalled the sound driver (for laptop) so that the laptop was plugged into the dock.  That did the trick.

    Dear community,

    We have just received laptop computer Intel (Acer Aspire VN7 - 792 G-74Y9), we are going to use with Windows 7 (64-bit).

    Now we have a problem with the audio driver that we fail to install. All other drivers are run without error.

  • I can't record new sound effects Director of windows.

    I can't record new sound effects Director of windows. I have a recording camera that can record sounds as well, and it works on my laptop, but it totally broke and now I have to use my computer at home. How do you store new sound effects?

    If you type tape in the box start the SEARCH Menu you can make use of this program?

    See the program Sound Recorder help for more details.

    • To use sound recorder, you must have a card sound and speakers installed on your computer. If you want to record the sound, you also need a microphone (or other audio input device).

    • You can play the audio file is saved on your computer by using a media player program.

    Maybe you can install and connect the camera to your computer and use that out there?  Your second computer recognizes the camera?  You may need to install the appropriate drivers for this camera model.

  • Windows 7 64-bit mouse pauses/freezes/stutters often accompanied by an event sound Windows

    Symptoms:

    Erratic mouse behavior. Mouse hanging, the gel for a full second or more, accompanied by a Windows event sound, generally. Sometimes, there is just a slight pause and no noise Windows event. Sometimes the mouse acceleration changes after freezing. Sometimes, more rarely, my mouse will be dropped by the operating system... the laser light on the underside turns off and I have to unplug the mouse and plug it in again so he can be recognized.

    What happens almost all the time. I want to use Windows mainly to play a game, World War II online: Battleground Europe. It is a shooting mmo first-person. This problem is annoying enough on the desktop. Unsuable for FPS games. I plan to have to file using Windows 7 64 bit for now.

    NOTE: My mouse (G3) Logitech MX518 Gaming tips works fine, without any problems whatsoever, under Windows XP Professional SP3 32-bit with all latest updates or on Ubuntu 10.4 (Lucid Lynx) 64-bit.

    -----------------------------------------------------------------

    Steps in my last attempt to solve the problem.

    I was looking not all parameters of the BIOS at once at the beginning. For example, I have disabled "Intel Speedstep" to see if that would solve the question. Then restarted in BIOS and disabled the C1E function when I discovered that disabling Speedstep alone does not resolve the issue. ECT, ect...

    I have not installed Norton Internet Security 2010 for awhile while I tried various solutions of Workaround available and listed below in case this is the question. No difference, so NIS 2010 is now installed.

    Remember, that this behavior occurs that when Windows 7 64 bit is installed properly.

    (1) clean install of Windows 7 64-bit, for the third time now

    (2) installed the Runtime Visual C++ 2008 64 bit v9.0.30729.4148 than kb973552/KB969706 downloaded from--> http://www.microsoft.com/downloads/details.aspx?displaylang=en&FamilyID=2051a0c1-c9b5-4b0a-a8f5-770a549fd78c

    (a) just in case Rebooted and then install the same version of the Visual C++ 2008 for 32-bit environment Runtime in Windows 7 64 bit

    (3) installed Windows 7 64 - bit drivers

    (a) Marvell Yukon 88E8056 Gigabit Ethernet on-board NIC Driver v11.24.5.3 (15/02/2010)

    (b) various software of Creative Labs creative Labs X - Fi Titanium 64-bit driver v2.17.0007 and all updates for them.

    (c) Software Driver of Intel Chipset v9.1.1.1025 (22/12/2009). Seems to just install an update from the hard disk of 64-bit driver.

    (d) ATI Catalyst 10.3 Driver

    (4) installed Windows updates

    NOTE: I have not installed the latest four updates for now, three of them are security updates have a publication Date: 09/02/2010. I decided to not install these due to a mistake of "Circular kernel context logger" that I already saw in the viewer of the event log, recorded by "Microsoft-Windows-Kernel-EventTracing" event ID: 2 now, I'm not having this issue.

    NOTE: I also installed a driver in option, the ACPI ATK110 driver, which installs the following file--> C:\Windows\System32\drivers\ASACPI.sys - he has listed as the version of the file 1043.2.15.37 and dated 29/03/2005. In a previous installation of Windows 7 64 bit, I downloaded an update of the present of Asus contained in a file/AMDCoolnQuiet_Utility_V21801_XPVistaWin7.zip utility and installed. I started the utility and he gave me the message that my system was not supported by "Asus Cool ' n Quiet. It's ASACPI.sys file was dated some time in 2009, rather than in 2005. Since my last Windows 7 install, I have currently a bit the 2005 version proposed by Windows Update installed. I don't know if this file is to load or used by Windows 7 64 bit. But I wonder...

    Is this a problem?

    (5) installed software v6.00.68 Logitech Setpoint (Version 4.90.80 driver) for Windows 7 64-bit

    NOTE: I have not installed this in previous installations of 64-bit Windows 7 and had hoped that this would cure the problem. No change, the problem still persists.

    (6) went into the BIOS and reset to the default settings

    (7) BIOS: Set A.I. OC (overlcock) to "Manual" and left to deafult values so that the CPU isn't overclocked automatically or manually sort

    (8) BIOS: Establish timimgs settings memory, memory voltage and the voltage Northbridge, according to my memory (memory Mushkin) manufacturer's recommendations

    NOTE: Again, I didn't have never had any problem at all in Windows XP Pro 32 bit SP3 or Ubuntu 10.4 64 bit with these settings. These operating systems will run an intensive game if I want to, throughout the day.

    (9) BIOS: The value of Intel Speedstep "Disabled".

    (10) BIOS: C1E (Enhanced Halt State) value to "disabled".

    (11) BIOS: Set the Mode of the ACPI Power / Suspend 'S3' only '

    (12) BIOS: Set ACPI 2.0 Support to 'Active '.

    NOTE: On, off, on any settings/functions above not has not solved the problem. I have I have not tried all the single 'combination', but in any case, make no change with the mouse.

    (13) in Windows 7, I selected the Option to 'High Performance' and the value "USB selective suspend setting" to "Disabled" with updated BIOS options as shown in steps 9 to 12 above

    NOTE: With BIOS defined that way there is no setting "Processor Power Management" in the Options of food, other than the 'political cooling system' (active/passive).

    I left this game to 'Active '.

    Is this a problem?

    (14) tried monitoring DPC latency with the download link for the "DPC latency Checker" utility No visible ears in the utility during the mouse freezes / breaks

    Hello again,

    Can I have found the solution that worked for me. It is probably too early to tell, I'll need more time to be sure. But in case he solved the problem for me, I'll post what seems to have worked as suggested on a post, I came across from another forum. Consider a guy who tried many suggestions, maybe that's the answer. Heck, I had tried a few other things that I have said in my original post. But in any case, so far, my system and mouse seem to work very well on the desktop for the last hour and a half. I have not tried yet game.

    (1) uninstall the Windows Update KB977074 (January 2010 stability and reliability update for Windows 7 and Windows Server 2008 R2).

    (2) reboot and leave your system for a couple / few minutes after the restart.

    (3) just in case... Restart again, and then reinstall the KB977074.

    (4) restart to complete the installation.

  • Windows XP Sound Recorder [sndrec32.exe] in Windows 7 64 bit?

    Utility tape recorder for Windows XP [sndrec32.exe] works in Windows 7 64 bit?

    The reason I ask: under XP, I use sound recorder to audition small sound files for possible use as system sounds. No sense to launch a 'real' drive just to play a .wav of 2 seconds.

    I know I could use the control panel of sounds and Audio for this (on XP) devices. But it's so convenient to the tape recorder on the Office Park and then drag and drop dozens of files .wav on it.

    The sound recorder in Windows 7 utility seems to be on the recording of the sounds, not to play them.

    XMPlay is a great and very light .wav player. It starts almost instantly. XMPlay is now my default .wav player replacing Sound Recorder (sndrec32.exe) in earlier versions of Windows. (XMPlay plays too, other formats, including video.)
