Hi, I've got a problem with a lenovo notebook G580 after Upgrade to Windows 10 Pro. Since that Moment, Sound system does not work. Two Drivers are shown in the System Control: Conexant Smart Audio HD Driver and Intel (R) Display-Audio; But both drivers work correctly regarding the system control. Restart the system. SFC or System File Checker is a Windows utility that lets you scan for system integrity by scanning corruption in windows system files and replacing missing or corrupt system files.

Windows 10 may get bugs sometimes, but the frequent updates released by Microsoft bring stability to the operating system. These numerous Windows updates are not just limited to security patches but also bring several device driver updates to safeguard and optimize your system.

However, there may be a situation where a Windows update fails to download or install successfully. And therefore, every time you shut down or restart your Windows device, you see the same update being installed repeatedly.

The annoying part is that even after a successful Windows updates installation, your system automatically starts installing the same updates again as soon as you reboot or turn ON/OFF the system.

Why My PC Keeps Installing the Same Update on Windows 10?

This mostly happens when your Windows system is not able to install the updates correctly, or the updates are partially installed. In such a case, the OS finds the updates as missing and thus, continues to reinstall them.

This is a serious issue as your PC may restart – without warning – to install the same updates, leading to permanent data loss, as the programs and utilities in use will get shutdown abruptly.

For such data loss situations, it’s best to use a reliable data recovery tool like Stellar Data Recovery Professional for Windows. This will help you recover the lost, deleted, and inaccessible data from not just the PC but also the various external storage media connected to it.

Methods To Fix the ‘Windows 10 Keeps Installing the Same Update’ Issue:

The following are a few workarounds that can help you fix this issue where Windows 10 is downloading and installing the same updates repeatedly.

1. Windows Updates Trouble-shooter

This is perhaps the easiest way to fix the issues related to Windows updates:

• Open ‘Settings’ in Windows 10
• Go to ‘Update & Security’
• Click ‘Troubleshoot’
• Click on ‘Windows Update’ under ‘Get up and running.’
• Then click on the ‘Run the trouble-shooter’ button
• The Windows Update trouble-shooter begins detecting problems. Wait for it to finish
• After the scan, the trouble-shooter finds the fix and asks you to either apply it or skip it. Click ‘Apply this fix.’

• Wait for a while until trouble-shooter applies the fix. Once it is done, close the trouble-shooter and restart the PC; then try to reinstall the updates.

In case the error is not resolved, proceed to the next solution.

2. Delete the Software Distribution Folder

Open the command prompt and then type each command followed by the Enter key to stop following services:

1. net stop wuauserv
2. net stop bits
3. net stop cryptSvc
4. net stop msiserver

Go to C:WindowsSoftwareDistribution and rename the Software Distribution folder as SoftwareDistribution.old

Similarly, rename C:WindowsSystem32catroot2 to Catroot2.old

Then restart the system and try to download and install the Windows updates. The services we stopped will start on reboot, or you can manually restart the services without restarting the system and resume installing Windows updates.

3. Uninstall the Problematic Updates

• Go to Control PanelProgramsProgramsand Features and click ‘View installed updates’ link in the left pane.
• Note down the update that keeps installing again and again.
• Right-click on the update and choose ‘Uninstall’.
• Grant admin access and then click ‘Uninstall’.

• Now reboot the system and then try installing the update again.

4. Download and Install Updates Manually From Windows Update Catalog

Windows Update Catalog facilitates downloading the Windows cumulative updates as well as significant updates that you can then install manually just like any other program.

• Under Windows Update, view update history and note down the updated version that is installing again and again. It must be something like KB12345678.
• Visit Windows Updates Catalog.
• In the search bar, enter your update version code and press ‘Enter’ or click the ‘Search’ button.

• Click the ‘Download’ button. A new pop up window appears.
• Click the update download link and then install it.

• Restart the system.

5. Run SFC Scan

SFC or System File Checker is a Windows utility that lets you scan for system integrity by scanning corruption in windows system files and replacing missing or corrupt system files. The SFC scans work via command line.

• Open the Command Prompt as administrator.
• Type command SFC /scannow and press ‘Enter’.
• After the SFC scan is complete, restart the system if it finds and replaces corrupt or missing files.

If no issues are found, it means system files are OK, and you can head to the last workaround.

6. Problem Still Not Fixed?

If none of those mentioned above methods works, it means there is some major issue with your system. To fix it, you need to re-install Windows. Hence, backup your data before proceeding to Windows 10 re-installation.

In case you are unable to create a backup, use theStellar Data Recovery Professional for Windowssoftware that can help you restore data from a Windows system that fails to boot due to Windows installation boot loop.

• Remove the drive from the PC.
• Use a SATA to USB cable or enclosure and connect the drive to another Windows PC.
• Install the software and follow the video tutorial below to recover your files.

Conclusion

Windows updates are crucial for your system’s stability and security. However, the updates may sometime get stuck at installation or download, and fail to install or keep installing repeatedly.

Such issues with Windows updates may cause data loss due to a sudden system restart. Therefore, change the windows updates policy – as discussed in the post – to avoid automatic system shutdown.

We also discussed various methods that can help fix a Windows PC if it keeps installing the same updates repeatedly. However, if these methods fail, use Stellar Data Recovery Professional for Windows to fully restore your deleted, lost, and inaccessible data.

Conexant Scsi & Raid Devices Drivers

Intel High Definition Audio (IHDA) (also called HD Audio or development codename Azalia) is a specification for the audio sub-system of personal computers. It was released by Intel in 2004 as successor to its AC'97 PC audio standard.^[1]

Features[edit]

The Intel High Definition Audio specification includes the following features:^[2]

• Up to 15 input and 15 output streams
• Up to 16 PCM audio channels per stream
• Sample resolutions of 8–32 bits
• Sample rates of 6–192 kHz
• Support for audio codecs (e.g., ADC, DAC), modem codecs, and vendor-defined codecs
• Discoverable codec architecture
• Fine-grained codec power-control
• Audio jack detection, sensing, and retasking

However, as of 2008, most audio hardware manufacturers did not implement the full specification, especially 32-bit sampling resolution.^{[citation needed]} Motherboards typically do not have any more than eight onboard output channels (7.1 surround sound) and four input channels (back and front panel microphone inputs, and a back-panel stereo line-in). Users requiring more audio I/Os will typically opt for a sound card or an external audio interface, as these devices also provide additional features that are more oriented towards professional audio applications.

Operating system support[edit]

MicrosoftWindows XP SP3 and later Windows versions^[3] include a Universal Audio Architecture (UAA) class driver which supports audio devices built to the HD Audio specification. There are UAA drivers for Windows 2000 and Windows XP SP2 as well. macOS has full support with its AppleHDA driver. Linux also supports HD Audio controllers, as do the OpenSolaris,^[4]FreeBSD,^[5]NetBSD and OpenBSD^[6] operating systems. However, it was first introduced in Windows XP x64 Edition and Windows Server 2003 x64 Edition with Service Pack 1. It had problems in some computers that have HD Audio in the motherboard chipset. This was fixed with Service Pack 2 for Windows Server 2003 x64 and Windows XP Professional x64 Edition.

Host controller[edit]

Like AC'97, HD Audio is a specification that defines the architecture, link frame format, and programming interfaces used by the controller on the PCI bus and by the codec on the other side of the link. Implementations of the host controller are available from at least Intel, Nvidia, and AMD.^[7] Codecs which can be used with such controllers are available from many companies, including Realtek,^[8]Conexant (including products of acquired Analog Devices' SoundMAX division),^[9] Tempo Semiconductor, VIA, Wolfson Microelectronics, and formerly C-Media. Realtek currently supplies most of HD Audio codec chips used on motherboards and standalone cards.

Nearly all chipsets for x86 processors and x86 SoCs, designed for consumer and embedded PC markets, introduced since 2005, implements integrated HD Audio controller. The most recent exemption in consumer chipset market is AMD TRX40 (launched 2019), which, for first time since the early 2000s, does not itself integrate any kind of audio controller. Instead, motherboard manufacturers places USB audio controller chip, in pair with usual HD Audio codec chip, to provide onboard audio functionality. The Realtek ALC4050H controller and ALC1220 codec is the most common pair used in sTRX4 motherboards.

Front panel connector[edit]

Computer motherboards often provide a connector to bring microphone and headphone signals to the computer's front panel. Intel provides a specification for that header, but the signal assignments are different for AC'97 and HD Audio headers.^[10]

The pin assignments for the AC'97 and HD Audio connectors are:^[10]

The HDA 3.5 mm subminiature audio connectors differ from connectors used in the AC'97 specification and general audio equipment. A regular 3.5 mm audio jack (which is used in AC'97) typically has 5 pins: one pin for ground, two pins for stereo signal and two pins for return signal.^[11] When there is no plug in the jack, the two stereo signals are connected to their return pins. When a plug is inserted, the stereo signals contact the respective channels on the plug and are disconnected from the jack's return pins. The HDA 3.5 mm jack does not have the two return audio signals; instead it has an isolated switch that senses the presence of a plug in the jack.^[12]

In the AC'97 design, the audio output is always sent to the jack. If the headphones are not plugged in, the jack directs the audio to the return pins that are connected to the speakers. When a headphone is plugged into the front panel jack, the audio signal goes to the headphones; the return pins are disconnected, so no audio signal goes to the speakers. For the microphone jack, the return signal pins ground the microphone input when the microphone is not plugged in. Many motherboards with AC'97 audio need two jumpers to short the pins in case no front panel audio module is connected, so audio passes to the speakers.^[13]

In the HDA design, when the plug is not inserted, the codec sends the audio directly to the speakers (the audio does not go out to the front panel and then loop back to the speakers). When the plug is inserted, the isolated switch inside the jack informs the motherboard, and the codec sends audio to the headphones. A similar isolated switch is used to detect when a microphone has been plugged in.

HD Audio can sense the presence of an audio dongle.^[14] A 10 kΩ pull-up resistor is attached to pin 4 (PRESENCE#). When the HDA dongle is plugged in, it pulls pin 4 to ground with a 1 kΩ resistor. The motherboard can determine if the dongle is plugged in by examining the logic level on pin 4. If the motherboard does not detect the presence of an HDA dongle, then it should ignore SENSE1_RETURN (pin 6) and SENSE2_RETURN (pin 10) signals. In AC'97, pins 2 and 4 are audio ground, but pin 4 is often disconnected. Consequently, an HDA motherboard would not detect the presence of an AC'97 dongle with a disconnected pin 4.

Intel warns that HDA dongles should be used with HDA motherboards:^[15]

It is strongly recommended that motherboard designers only use Intel HD Audio analog front panel dongles with the Intel HD Audio analog front panel header to insure that the jack detection and dynamic re-tasking capability is preserved. Passive AC’97 analog front panel dongles (ones which leave the 5V Analog pin-7 line unconnected on the dongle) may be used with the Intel HD Audio analog front panel header. But note that the front panel jack detection and re-tasking functionality will be lost as the AC’97 jacks cannot support connection to the SENSE line. In addition, software must be aware that an AC’97 dongle is being used with an Intel HD Audio analog header since the software might need to dedicate codec ports that are connected to the header to meet the product’s intended functionality.

The different signal assignments can cause trouble when AC'97 front-panel dongles are used with HDA motherboards and vice versa. An AC'97 dongle returns audio on pins 6 and 10 rather than a digital plug sensing signals. Consequently, a loud audio passage may make the HDA motherboard with AC'97 dongle believe that headphones and microphones are being plugged and unplugged hundreds of times per second. An AC'97 motherboard with an HDA dongle will route the AC'97 5 V audio supply (pin 7; silence) to the speakers instead of the desired left and right audio signals.

To avoid this, some motherboards allow choosing between HDA and AC'97 front panels in the BIOS. Even though the actual audio hardware is HD Audio, it will allow using the AC'97 front panel that way. Likewise, some modern enclosures have both an 'AC'97' and an 'HDA' plug at the end of the front-panel audio cable.
