In fact, the HDMI audio is specifically related to the 'High Definition Audio Device' listed in Device Manager. Since HDMI sound is also coupled with video, I figured there is a good chance that the video card driver might be at fault. At this point, I went into Device Manager and deleted his video card (Intel HD 4600). This made the screen go. Resolve the audio driver problem To resolve this issue, download and install the Microsoft Universal Audio Architecture Bus Driver (SP32646, version 1.00, rev. A) or later from the HP Drivers and Downloads page. IDT High Definition Audio CODEC. A device attached to the system is not functioning. Under the Sound, Video, and Game controllers - AMD High Definition Audio Device and under sound settings it say 'not plugged in' Now, the default speakers say that the driver that is installed MS says is the best one for it. I had a unknown PCI device that I found the drivers for; turns out they were for audio. Once I installed them the sound started to work but now I have a new device that is coming up with a question mark in the device manager. It is the modem device on high definition audio bus. Can someone please help me find the driver for this device?

More Information
The new UAA describes a class driver architecture for computer audio solutions that are supported in Microsoft Windows operating systems.
An audio device that is UAA compliant can rely completely on the operating system for driver support. Therefore, the hardware vendor does not have to supply a custom driver for the device. Microsoft plans to supply UAA class drivers for the following classes of audio device in Windows Server 2008.
USB Audio
IEEE 1394 AV/C
High Definition Audio
A High Definition Audio device complies with the Intel High Definition Audio specification. A High Definition Audio device connects to the PCI bus or to the PCI Express bus. This High Definition Audio device can reside on an internal audio card, or it can be part of an integrated motherboard chip set. The update that is described in this article supports the spring 2004 Intel initial hardware release of High Definition Audio-compliant solutions.
The third-party products that this article discusses are manufactured by companies that are independent of Microsoft. Microsoft makes no warranty, implied or otherwise, regarding the performance or reliability of these products.
The advantages of UAA over the current audio industry solution, AC’97 Audio Codec, include the following.
For users
Simpler installation of audio peripherals
Increased system stability
Easier installation of audio drivers
Increased performance
Glitch-free audio
Increased security for protected content
Reduced requirement for vendor-supplied drivers
Reduced requirement to upgrade drivers
Guaranteed basic audio support for UAA-compliant devices

For OEMs and hardware manufacturers
Reduced software development, testing, and support
Reduced exposure to product support calls and to product returns
Easier phase-out for products at 'end of life'

The HD Audio bus driver is the only software component that directly accesses the hardware registers of the HD Audio bus interface controller. The bus driver exposes the HD Audio DDI that its children--instances of the function drivers that control the audio and modem codecs--can use to program the HD Audio controller hardware. In addition, the bus driver manages the HD Audio Link hardware resources, which include the DMA engines and bus bandwidth. Function drivers allocate and free these resources through the HD Audio DDI.
The HD Audio bus driver:
Audio Device On High Definition Audio Bus Driver Xp Dell Download
Queries the codecs on the bus and creates children to manage the codecs.
Handles interrupt service routines (ISRs) for unsolicited responses and propagates the unsolicited responses to its children.
Passes commands from its children to the codecs and retrieves responses from the codecs.
Sets up the DMA engines that transfer data to or from the cyclic buffers.
Manages bus bandwidth resources on the HD Audio Link.
Provides access to the wall clock register and link position registers.
Provides synchronized starting and stopping of groups of streams.
The HD Audio bus driver does not provide:
An interface for programming a DSP or additional registers that are not defined in the Intel High Definition Audio Specification.
Prioritized bandwidth management.
During device enumeration, the HD Audio bus driver detects the codecs that are attached to the HD Audio controller's HD Audio Link. For each codec, the bus driver loads one function driver (if available) for each function group that it finds within the codec. For information about function groups, see the Intel High Definition Audio Specification at the Intel HD Audio website.
