Asus z690 no optical audio

I have a z690 D4 motherboard and I can’t get the optical spdif audio working. I checked the cable to make sure it is working and everything works fine. I did notice the USB audio is gone in my device manager but I haven’t been able to find a way to reinstall it.

I’ve updated all the drivers and it still doesn’t work. I have no idea what else I can do or what I’m missing.

Hello, @Joeydee 

May I ask if the situation you described happened after any changes were made? For example, updating the BIOS or connecting an external device
Could you please confirm if you are currently using the PRIME Z690-P D4 and have updated to the latest BIOS version 3010 released on December 28, 2023?
Regarding audio output under the system settings, have you selected "S/PDIF Output"?
Have you tried cross-testing with different connection cables or other optical digital audio devices?
Could you share a photo of the optical S/PDIF out port during startup?

Thank you.

sharing complete hardware info & software config details will help us better understand the issue 🙂

The thing is I never tested the optical port before so I don’t know if this is a new problem or not. 

I’m using the TUF Gaming Z690-Plus WiFi D4. I also have the latest BIOS installed. I installed Armoury crate a week ago and also updated all the drivers listed in the program. 

On windows 11 I don’t see any option at all for S/PDIF output. All I can see is the Realtek Digital Output setting but theres no option to change between 3.5mm or optical audio. In the Realtek Audio console theres the digital output that shows the audio going through and the Digital S/PDIF connection is highlighted in white letters.

I’ve tested the cable and equipment on a tv and PlayStation and it all works great through the optical cable. On the PC I can see the optical port is working correctly cause the red light is showing through the cable. 

I can take a photo later today and post it during the startup.
