Laptop no audio device issue

  1. I was recently given a Toshiba satellite l505-es5018 that was having virus issues and was incredibly slow. I reformatted and installed windows 7 32-bit, and had everyone working perfectly with exception of the audio. I have the red "X" over my volume control and the "No audio output device is installed". Device manager has nothing about sound/audio card, and i have no options in CMOS for turning my integrated sound on or off. Also, there is no sound through headphone or external speakers.
    Ive downloaded countless drivers from toshiba, realtek, and other software. And ave gone so far as to take the machine apart and check the connections.
    Any help on what this could be? Busted audio components on motherboard? 32-bit windows 7 not compatible?
    Any help would be great.

    Have you run Windows Update until there are no more found? My search pointed to Windows 7 64-bit. Why 32 bit for yours?

    Try Windows update as suggested. If still a problem

    List any Problem Devices
    • Click Start->Run, enter: msinfo32. Click the + sign next to Components to expand it
    • Click Problem Devices. Anything appear?
    • If yes, click on it, Ctrl-A to select all, Ctrl-C to copy it, Ctrl-V to paste into next post
    • On the other hand, if no devices are listed, tell me so
    Generate and attach a DirectX report
    • Click Start->Run, enter dxdiag
    • Notice progress in lower left window corner
    • When done, click Save Information button and save to your Desktop
    • In TechSpot, use the paper clip icon to attach the report. (If you don't see icon you may need to first click Go Advanced)

    What was the previous OS before the format? I'd check for devices with yellow question marks in device manager. Possibly just the audio driver isn't available. You might just need to google for Win7 drivers for your audio (check the laptop manufacturer site first). Otherwise it might be dead or disabled in bios.

    Judging from the specs I see on my google search, it should have drivers available. Just a question of finding them - assuming the audio is not broken.

    Hi Darth Shiv,

    I am having the same problem and did the steps you instructed above (I feel like I've tried everything, reinstalling RealTek, disabling and then enabling, deleting it and having windows update the software). This is what the System Information told me:

    NameRealtek High Definition Audio
    PNP Device IDHDAUDIO\FUNC_01&VEN_10EC&DEV_0268&SUBSYS_103C30CC&REV_1000\4&257318AE&0&0001
    Driverc:\windows\system32\drivers\rtkvhda.sys (, 2.26 MB (2,366,752 bytes), 6/9/2009 10:13 AM)

    NameUnimodem Half-Duplex Audio Device
    PNP Device IDMODEMWAVE\0\{91DBFB57-0F21-48DC-821A-5EB3EC5829A6}
    Driverc:\windows\system32\drivers\modemcsa.sys (6.0.6001.18000, 18.00 KB (18,432 bytes), 6/10/2008 9:08 AM)
    Any assistance would be so greatly appreciated
    My Best,

    @Lauren G

    If you'd like assistance, please go back to the instructions from the earlier post. Please reply with the list of msinfo32 Problem Devices and an unedited copy of your dxdiag report.
