I'm trying to use Logitech Z313 speakers with my PC, but Windows doesn't detect any audio output device. I installed the Realtek audio drivers from the motherboard manufacturer's official support page, but Realtek audio still doesn't appear. The speakers are powered on, and the 3.5 mm plug is connected to the computer. The motherboard is an MSI B450M-A PRO MAX II. What should I check next?

First, make sure the plug is in the motherboard’s rear green audio jack, not the microphone or line-in port. Then check Device Manager under “Sound, video and game controllers” and “Audio inputs and outputs.” If Realtek is missing entirely, install the audio driver specifically listed for the B450M-A PRO MAX II, restart the PC, and check Windows Update for optional driver updates. You can also look in the BIOS to confirm onboard HD audio is enabled.
Windows may simply have no output device selected, but if it says no output devices are found, this is probably a driver or hardware-detection issue rather than a speaker-selection problem. Try removing any failed or unknown audio devices in Device Manager, rebooting, and reinstalling the motherboard audio driver. If the onboard audio still never appears, test the speakers with another device and consider using a USB audio adapter to determine whether the motherboard’s audio hardware is faulty.
