If you’re facing issues with your audio DAC (Digital-to-Analog Converter) not working after recent Windows updates, you’re not alone. Many users have reported similar problems, particularly regarding USB devices after system updates. Fortunately, there are steps you can take to resolve this issue.
First, let’s summarize the problem. After you installed a couple of updates, your USB-connected DAC stopped working, and you received an error stating it couldn’t start due to "Not Enough USB Controller Resources." You’ve already attempted a few basic fixes like restarting the device, trying different USB ports, and reinstalling the device through Device Manager, but the issue persists.
Here’s how to potentially fix the problem:
-
Check USB Power Settings: One common reason for USB devices to fail is power management settings.
- Open Device Manager (you can search for it in the Start menu).
- Expand the "Universal Serial Bus controllers" section.
- Right-click on each USB Root Hub and select "Properties."
- Go to the "Power Management" tab and uncheck "Allow the computer to turn off this device to save power."
- Click OK and restart your computer.
-
Update USB Drivers: Sometimes, your USB drivers need an update.
- In Device Manager, expand the "Universal Serial Bus controllers" section.
- Right-click on the USB controllers and select "Update driver."
- Choose "Search automatically for updated driver software" and follow the prompts.
-
Uninstall and Reinstall the USB Controller: You might need to uninstall the USB controller and allow Windows to reinstall it.
- In the Device Manager, right-click on each USB controller and select "Uninstall device."
- After uninstalling, restart your computer, and Windows should automatically reinstall the necessary drivers.
-
Rollback Updates: If the problem started after the recent updates, rolling back to a previous version might be worth a try.
- Go to Settings > Update & Security > Windows Update > View update history > Uninstall updates.
- Look for the recent updates related to Windows or .NET Framework and uninstall them.
- System Restore: If all else fails, you may want to consider performing a system restore to a point before the updates.
- Type "Create a restore point" in the Start menu and select it.
- In the System Properties window, click on "System Restore" and follow the prompts to select a restore point.
By following these steps, you should be able to resolve the issues with your audio DAC. Make sure to test it after each step to see if the issue is fixed before moving on to the next one. If the problem persists even after trying all these solutions, consider reaching out to the DAC manufacturer for support, as there may be a deeper compatibility issue due to the recent updates.
With patience and persistence, you’ll likely find a solution that works for your setup!
