    Hi I don't have sound and haven't for the past few days and then this morning a Found New Hardware Wizard keeps popping up trying to install software for an Unknown Device on High Definition Audio Bus.

    In the Device Manager, there are yellow question marks near Other Devices and then below it, in sub categories is a list of at least 20 (!) Unknown Device on High Definition Audio Bus.

    In the Audio Device section, there are NO Playback Devices, NO Recording Devices, No Midi Playback and the same in the Voice section. Usually I have Realtek listed there.

    Thank you for any help.

    Is your sound on-board or is it PCI? Try reloading the drivers for your sound.

    Hi Lance,
    I guess it's PCI as it usually is Realtek AC '97 Audio that comes up as the default Audio device for Sound playback.
    Realtek is listed under the Hardward devices in Sounds, Speech and Audio devices and says it is working properly, but that doesn't mean much!!

    Also sometimes I have another sound device, Bluetooth AV/HS Audio which takes over the Realtek AC as the default by itself, and this doesn't produce any sound at all (this is what I thought happened in the first place as it has happened quite a few times in the past.) Can I safely delete this one if I find it?

    I cannot find the cd for the Realtek driver, so I'm d/loading it now from Cnet and will reload it so it will work once more!

    Much appreciated your answer and help!

    :)Tes
