Error 917 can be a ghost left behind by a bad Windows Update.
No screwdriver required.
Alternative: In older Realtek HD Manager, go to the "Information" tab (the "i" icon). Click "Connector Settings" (the folder icon). Uncheck "Enable auto popup" and then re-check it to reset the sensor.
If software fails, it’s time to get physical. 917-front audio not connected
Tools needed: Phillips #2 screwdriver, flashlight. Safety: Shut down PC, unplug power cable, press power button to drain residual charge.

Reseat the Cable:
Test before closing. Plug power in, boot up, and test the front jack. If error 917 disappears, you have solved the problem.
At first glance, "917" appears to be a vendor-specific or driver-level code. Unlike standard Windows errors (e.g., 0x887A0006), 917 is obscure—suggesting it may be a custom return value from a driver’s I/O control request or a callback failure from a user-mode audio service.
Possible origins:
The "front" qualifier indicates a spatial or channel-position identifier—not necessarily a physical front panel jack. In multi-channel interfaces (e.g., 18i20), front channels often refer to outputs 1-2 (main monitors). A "917-front" could mean:
Channel 9, sub-slot 17, front segment — rare, but possible in large Dante or MADI systems.
If you have tried all of the above and the "917-front audio not connected" error remains, you might have a permanent hardware failure on the mainboard’s detection chip. Here is how to work around it.
