    No sound in speaker but in Headphone for IDT Codec


    Hi Guys,
    Facing a weird problem for a long time (3 months or more but got chance to google it today). Its a dell studio 1555 with IDT High Definition Audio Codec with windows 7 x64 Ultimate OS. I had to give a clean OS after a fatal crash and sound is giving a weird problem from then. No sound through my speaker;only through headphones. If I remove headphone then IDT setup options pop ups and I cant' work until headphone is there....

    Downloaded the latest driver from dell's recommended site and still not good...
    tried to uninstall and restricting the auto installation by windows from "gpedit.msc" and manual installation through the latest driver..yet nothing happened...
    growing Mad...I know it is drivers problem but can't fix it...help me plz...

    BTW: Systeminfo.exe shows two sound card
    1) IDT
    IDT High Definition Audio CODEC

    2) Microsoft
    High Definition Audio Device


    Please help me out...please please...

    On a Dell you need to use the Dell supplied sound driver for proper operation. Delete the "Microsoft" which was apparently installed when you installed Windows. Go to the Device Manager and uninstall the Microsoft, just leaving you the Dell. Uninstall the Microsoft and then restart the PC and see if it gets corrected. Make sure your IDT sound card "Speakers" are set as the Default Playback device in the Sound Panel.

    Why did you do a manual reinstall? There is a Dell recovery partition on the hard drive (or at least was when it was new), accessed by F8 at POST that would have restored everything to the original factory condition (and no discs or driver downloads needed). That is the best way to reinstall.

    That picture is too small to read. HERE is the Dell users manual which details what all the jacks are.

    There is an option for the SoundBlaster Xfi MB SOFTWARE enhancement to the integrated audio. However, that is only listed in the Vista 32 bit downloads, not Windows 7 as this is not Windows 7 compatible. Dell sells a different Creative/SoundBlaster software enhancement on new Windows 7 systems. If you have that installed it may be causing some of your problems.

    Worked for me


    I have a studio 1555 with the same symptoms. Sound through headphones, no sound through speakers. I found a fix that worked for me, from the following site...

    Headphone Jack FAQ - Laptop Audio Forum - Laptop - Dell Community

    Hope it works for you!

    2. Workaround for Studio XPS 1640, Latitude 6400, and Studio 1555

    1. Open the "Sound" control panel.
    2. Select the "Playback" tab.
    3. Select "Independent Headphones" (called "Communication Headphones" in newer models) as the playback device.
    4. Select the "Recording" tab.
    5. Select "Microphone Array" as the recording device.
    6. Select "Properties".
    7. Select the "Listen" tab.
    8. Check the box labelled "Listen to this device".
    9. In the dropdown box labelled "Playback thru this device" select "Independent Headphones".
    10, Close open dialog boxes and return to the "Playback" tab.
    11. Select ""Speakers/Headphones" as the playback device.
