No sound via HDMI after upgrading Vista to Windows 7

Data sheet:

HP Pavilion Elite m9515y

Sound:

Realtek ALC 888 chipset s

Video:

GeForce 9600 GS

With the original operating system Vista, I could right-click on the speaker in the taskbar and select the playback device and make the default output HDMI.  I erased my drive and installed Windows 7.  Now under the playback devices I have not the HDMI option.  According to me, speakers, headphones and Realtek Digital Output.  Sounds works fine with speakers or headphones.  I tried to install the latest audio and video of Nvidia and Realtek drivers.  I tried to go back to the original Vista drivers.  Nothing works.  At the moment I use a stereo cable to connect my PC from the headphone jack on my TV, but wish that I could get good audio HDMI works with Windows 7.  Anyone else having a problem with these chips sets?

PROBLEM SOLVED!

The motherboard has two S/PDIF outputs.  A pass by a connector and the wire internal graphics card HDMI.  The other goes to a RCA Jack on the back of the computer.  During normal operation of Vista, the driver probably did some function to determine if the HDMI connection is used, so that it does not disturb the owner of a system without card HDMI with this audio port additional inaccessible appear under their playback devices.

Unfortunately, the BIOS or the audio driver or video card driver require an update for Windows 7.  No matter what function is used to detect if the HDMI connection is present does not, if ever it comes in the playback devices.  I hope someone at HP or Nvidia, Realtek is tuned for this.

Until the corrected drivers or BIOS, I found a coaxial wire thin with an RCA connector on one end and who connected to the Digital Audio output on the back of the computer, transferred this thread in my machine, then cut and solder this wire over the graphics card HDMI input S/PDIF.  It seems stupid, but works like a charm.

So ends 3 days of aggravation.

  • C6150 does not print after upgrading Vista to Windows 7

    Hello.

    I have an AIO C6150, which worked fine under Vista.  Since I've upgraded to Windows 7, I can't get a printout of any application or the windows test print.  The test print HP Solution Center works very well.

    -Printer is connected wireless

    -J' installed the latest driver from HP which is supposed to be ready for Win 7

    -J' have also installed the patch they recommend after upgrade to Vista

    There is no error.  Print job appears briefly in the Print Manager window, then disappears as if it printed.  I am at a loss, any help would be appreciated.

    Paul

    I found my issue as well, with the help of HP technical support.  Basically, it is a conflict between the generic drivers Windows and whole new drivers from HP.  Once that happened, it was a nightmare to get all the 'remains' of these two uninstalled drivers.  Once we did it, we have been able to recharge the HP driver package and everything works fine.

  • Cannot print from IE 8 after upgrading Vista to Windows 7

    My laptop (HP Elitebook 8530w) uses two HP printers: Color LaserJet CP3525x (at work) and Deskjet 6940 (at home). Both printers are accessible via a local network.

    I've recently upgraded to Vista Enterprise to Windows 7 Enterprise.

    All still print fine (from Word, Adobe Reader, Windows Photo Viewer, etc.), except for IE 8! When I try to print a web page in IE, it only prints the page header, and in the contrary case, the journal will be empty. This problem occurs on both printers. (And of course this good worked before the upgrade.)

    Any ideas? Thanks for any help.

  • Receiving IR of HP and MC remote control does not work after upgrading Vista to Windows 7.

    I upgraded a laptop HP dv9249us for Win 7 Ultimate (64 bit) and Home Premium (32 bit) respectively of Vista and an HP HDX 18 and found that the small remote controls supplied with the PC HP no longer work the IR receiver to control WMC.  For the moment I tried to find a solution for the dv9249us, as the HDX has also a greater remote specialized for the tv tuner, which is still working, but I found that HP did not provide software Win 7 upgrade for this model.  I tried a thought fix it was to be a known side effect of the upgrade process because he appeared in two different rooms and found a HP IR driver referenced to correct this problem for another model called ENE CIR Receiver Driver (sp41645.exe) and install this on the dv9249us without result.  When you check the Device Manager on the dv9249us I have not found reference to an IR unit either in the areas of Human Interface or Universal Serial Bus controller.  I found a reference IR in the section of the Human Interface of the HD-18 referencing an ENE CIR Receiver.  Ideas that you could provide for a non-professional would be appreciated.

    I can not find a model of dv9249 specifically on the hp site. I found the dv9200
    series. you have a link to your specific model?
     
    in all cases, try to remove the Device Manager devices and if requested if you want
    to remove drivers, select Yes. then make a stop at cold and then turn it on.
    Finally, see
     
    link of a person found an alternative driver that solves the problem) on the page

    It seems that several HP models affected related issues.
     
    If this does not resolve the problem, suggest that also posting in the forums of HP.

    Original thread: Windows 7 upgrade messed up the screen resolution

  • Built-in mic stop working after upgrading Vista to Windows 7

    I've checked everything I can think of.  Nothing is cut.  When I go into control panel - sound - recording, there is a green check mark on the mic, but it captures all the sounds.  The microphone worked before I upgraded.  Any ideas?

    Thank you.

    It is always helpful if you identify your OS by saying also that it is 32-bit or 64-bit.

    Here's where tit portal for your laptop support pages are.

    Go into the control panel. Select sound. Select the record. Select Configure. Select Configure microphone.  You should see what I have in the next image if all goes well at this point. If you speak into the microphone, you should see a green bar mobile.

    view your results.

  • C4480 does not print after upgrading Vista to Windows 7

    Hello

    I bought a C4480 & installed on my laptop running Vista.  I bought recently installed Windows 7, it & printer worked OK. 2 days ago HP sent the file: PS_AIO_03_C4400_NonNet_Full_Win_WW_130_140.exe, (1/1, 205.09 M)

    I downloaded & installed, now the printer does not print. It scans ok just will not be printed. Called HP & said it was Microsofts problem. told by Microsoft of $ 80 or reinstall my computer back to the factory default settings. Not knowing much about computers I'm not want to do. The computer tells me the spool of printer off & to start but when I open the printer spool is on. I hope you understand that this is my 1st post.

    There is a patch for this here.  Try it!

  • No output micro HDMI after upgrading to Win 8.1

    My new Yoga 2 Pro has a secondary display connected via micro HDMI port. He first worked as a charm. But after upgrading to new Windows 8.1 (this is done automatically) it is no longer produced anything to micro HDMI port. Display and the cable is fully functional. But even if the screen is turned on, the computer is unable to save and apparently it cannot display anything. Micro HDMI port seems to be non-existent.

    After upgrade of windows, I tried to uninstall / reinstall the display driver. I also upgraded to Win 8.1 Intel drivers versions found on the support site of Lenovo (including the BIOS display driver Intel HD 4400 15.33.18.64.3496 and chipset 9.4.0.1026, 76CN38). But nothing seems to work.

    A solution in the forum is to change the cable, but I think that there is no sense here that the cable worked perfectly until the upgrade.

    Can anyone suggest a solution?

    Lenovo: Is there a driver for Intel version 15.36.0.3652 on the Intel Web site. However, there is a blockage on the pilot, you need to install own Lenovo driver downloads. Can you check if this solves the problem?

    Sorry, a new cable solves the problem

  • Upgrade Vista to Windows 7, files using the second internal hard drive and Windows Easy Transfer.

    I have a desktop pc with 2 internal hard drives.  A hard drive has the BONE and the second hard disk is a separate partition.  (I do not combine hard drives using RAID.)  If I upgrade Vista to Windows 7, the upgrade will be to reformat hard disks or just a hard drive with the operating system?  Should I remove the second hard disk of the computer just to be sure?  The second hard drive must be reformatted for use with Windows 7?

    Thank you.

    You must install the upgrade in the Vista operating system.
