Audio device not being detcted on B550-F Gaming Wifi II

[Tomism]

Hi,

I've installed the motherboard (Asus GOG B550-F Gaming Wifi II) and have installed Windows along with all the drivers. However Windows is not recognising the built in audio device (I'm assuming it is Realtek). I've tried both Windows 10 and 11 and also Pop OS (Linux) and none of them are detecting the audio output device.

I've tried the online audio & chipset drivers and also the drivers on the CD that came with the motherboard. I've also flashed the bios twice with different bios versions from the ASUS website to see if that helped.

This is very frustrating as I've tried everything I can think of.

Also I don't know if this is relevant but the system wont run unless I put a graphics card in. The inbuilt graphics ports don't appear to work.

Can anyone suggest anything to try?

Thanks

Hello, @Tomism 

Due to the ongoing local holidays in our area, my response time may experience delays.
I apologize for any inconvenience the delayed replies may have caused.

Could you please provide information on how long you have been using this PC build?
May I ask if the situation you described happened after any changes were made, such as adjusting the BIOS settings or connecting an external device?
Which two BIOS versions you updated to, whether you attempted the latest version 3607, and if you cleared CMOS after completing the update?
Regarding the audio driver, have you installed the V6.0.9411.1 released on the ROG STRIX B550-F GAMING WIFI II website?
We recommend referring to the steps outlined in "[Motherboard] Troubleshooting - Audio with no sound" if needed.
Regarding the integrated graphics, what is the model of the CPU you currently have installed, and does it support integrated graphics?
Typically, when no GPU is installed and only a CPU with integrated graphics is supported, connecting the monitor to the HDMI or DP ports on the rear side of the motherboard allows for video output from the integrated graphics without additional configuration upon booting up.

Thank you.
