Windows 10: No audio device is installed. Possible BIOS/UEFI issue.

Windows 11. The speaker on the task bar has a cross over it and hovering over this gives the message that "No audio device is installed".

Audio device issue

Hi Venu,

Incompatible audio device drivers are known to operate against the method that Windows 10 follows. First, uninstall the audio driver, then follow these steps to resolve the issue:

• Right-click on the name of your PC at the top of the list of devices in
  Device Manager.
• Select Scan for hardware changes to reinstall the device driver, or download and install the latest version from the manufacturer’s website.

Let us know how it goes.

 

Trouble installing windows 7 on RAID in UEFI

As the title says, I'm trying to install Windows on a RAID array in uefi on my Maximus V Formula. When using legacy ROM I can install just fine but I go into CSM and change settings to UEFI only, I can build the array in the UEFI Raid driver (IRST tab in "BIOS") but the array does not show up in the boot menu and when I try to install windows (boot from UEFI DVD drive), The drive does not show up in the Windows install. The next thing I tried was to enable UEFI and legacy oprom in CSM, boot from UEFI DVD drive and install to the RAID array (probably detected by legacy oprom) and it will install. After first reboot, Windows Boot manager will show up as an option in the BIOS boot menu so I set that as first boot device and reboot. I will get to the starting windows screen and then BSOD (too quick to get codes) The last thing I tried was Changing to legacy mode and installing windows to a different drive. once installed, I initialized the Raid array as GPT and rebooted, changed csm back to UEFI only but they RAID array still doesn't show in the boot device list so I repeated the earlier process hoping that It might work because I had initialized as GPT but it still BSODs on starting windows screen. Any help or suggestions would be greatly appreciated
