    Hello jigs,
    Go to control Panel >> Sounds and Audio Device >> In Audio TAB >> select “Use only default devices”
    Then under Volume TAB >> Device volume >> Advanced >> Options >> Properties >> Plackback/Output device >> select only Master volume and wave, un check all others.
    Under Recording/Input device >> Microphone only and turn the volume to max and enable microphone boost under advanced. Now try on chat. This may solve your problem.

    Hi Prasad,
    i have installed XP on c785tu.
    bluetooth is not working. i think drivers are not available. can u please tell me from where i can download them??

  9. saysprasad says:

    Hello Mr.Naveen,
    C785TU doesn’t have an inbuilt bluetooth. The unknown device showing on the device manager is quick launch buttons, installing the corresponding drivers may solve the problem.

    hello all,
    i am providing you the audio driver for compaq laptop….
    see even on hp/compaq site under windows xp thy hv not given audio driver so i am providing you the link………..

    IT WORKS………I HAVE DONE IT WORK FOR MYSELF

    Our Presario is shipped with the High definition Audio controller, so you have to first install the Microsoft UAA driver and then install the Audio driver.
    Here is the link for Microsoft UAA driver link:
    http://asia.giga-byte.com/FileList/Driver/motherboard_driver_audio_realt
    Installation Instructions :
    1. Download the SoftPaq .EXE file to a directory on your hard drive.
    2. Execute the downloaded file and follow the on-screen instructions.
    3. Restart the notebook when the installation is complete.
    Or
    Download the driver to the computer which you are using to chat with me and transfer it to the Notebook using any USB device or copy the drivers to a CD or DVD and install them in the Notebook.
    Make sure to restart the system after installing the UAA driver and then install Audio driver from the below URL.
    Conexant High Definition Audio Driver :
    ftp://ftp.hp.com/pub/softpaq/sp34001-34500/sp34200.exe
    This will create a swsetup folder in c drive (“C:\swsetup\sp34200”)

    Installing Audio drivers may result in an error. But continue with the following steps to get the audio driver installed correctly. Installation instructions of Audio driver:

    1. Click on Start and select Run. Now type devmgmt.msc and press enter.
    2. Right click on “Audio device on High Definition Audio Bus” and click update driver.
    3. Select “Install from a list or specific location”
    4. Click Next. Then select “Don’t search, I will choose the driver to install”
    5. Click Next and then select “Sound, video and game controller” from the list.
    6. Click Next and then click Have Disk.
    7. Click Browse C:\swsetup\sp34200 folder and select the .inf (wis30b2a) file and click open and Continue with the onscreen instructions.

    Hi Prasad,

    First of all, compliments for the great website you have put together. I have a problem with wifi on my C785tu laptop running windows XP. I have installed the HP wireless assistant and wireless driver mentioned on the home page of your site for C785tu. I saw the WLAN was still disabled. I have gone through other posts in this page but haven’t found a solution to thisproblem yet. I dont see any network adapter for wireless in Device manager > Network adapters. I also installed ftp://ftp.hp.com/pub/softpaq/sp34001-34500/sp34136.exe but to no avail. I’m sincerely hoping that you could help me out here.

    Thanks in Advance. Anticipating a response from you.

    Regards,

So what kind of problem this may have and what do you suggest the solution for this? Is it something hardware related problem? Please suggest me. I will be thankful to you.
