Hi, Jack_654
Welcome to Microsoft Community.
We understand that you want to get the HP Spectrex360 DTS Audio Driver. It should be explained that DTS audio drivers are usually provided by the computer manufacturer or sound card device manufacturer.I noticed that your device is HP SpectreX360 16-inch, after I checked on the official HP website, HP doesn't officially provide the DTS driver for your device model, please refer to (I'm not sure about your specific model, so I'll post all the relevant links):HP Spectre x360 16 inch 2-in-1 Laptop PC 16-aa0000 Software and Driver Downloads | HP® SupportHP Spectre x360 16 inch 2-in-1 Laptop PC 16-f1000 Software and Driver Downloads | HP® SupportHP Spectre x360 16 inch 2-in-1 Laptop PC 16-f2000 Software and Driver Downloads | HP® SupportHP Spectre x360 16 inch 2-in-1 Laptop PC 16-f0000 Software and Driver Downloads | HP® Support Disclaimer: Microsoft provides no assurances and/or warranties, implied or otherwise, and is not responsible for the information you receive from the third-party linked sites or any support related to technology. So it is recommended that you check with HP officials to see if your device model comes with the DTS audio driver by default, and if so, ask HP for the factory image file of the HP Spectrex360 and install it again to see if the DTS audio driver works.Also, I noticed that you have already done a fresh install of the system, so I suggest that you can choose to restore the factory settings to see if you can recover the DTS audio driver:- Click on the Start button in the bottom left corner of the screen and select Settings.- In the Settings window, select “System” and then click “Recovery”.- In the recovery options, select “Reset this computer” and then select “Initialize computer”.- In the pop-up window, select “Delete everything” to completely reset your computer or “Keep my files” to keep your personal files.- Select “Reinstall Windows 11 locally” and click “Next”.- After confirming the settings, click “Reset” and wait for the reset process to complete.If you have any progress, please feel free to contact us.
