Question No audio with Ryzen 5 2600

[Putermaker]

I have had three MSI motherboards with this same issue... If I install a Ryzen 3 2200G with integrated graphics or with a GTX 1060 video card all works as it is supposed to. However, if I swap out a Ryzen 5 2600 the Realtek onboard audio is no longer detected. I have had this with an MSI B450M Bazooka and (2) MSI B450M Bazooka MAX Wifi boards. I have never heard of a faulty CPU causing sound issues, but could this be the case? It is a used CPU, but all the pins appear to be straight and I've build hundreds of PCs over the years. Has anyone got a suggestion. (MSI support was zero help, as anticipated.)

What type of connection are you using? (HDMI, DP, Analog, etc.)

Well, the GTX 1060 is connected via DVI at the moment. I have used HDMI as well. The speakers are connected to the standard green socket on the MB. With the 2600 installed Windows only sees the nVidia HDMI for sound and the Realtek chipset disappears completely. With the R3 2200G the Realtek comes back and sound works fine.

That is certainly odd. Are you sure you have the Realtek Audio Driver installed? (Not that it would make a difference in most scenarios, but you never know.)

Did you clear CMOS? Have you changed output device to the Realtek Output? And connected your speakers/headphones to the motherboard or front panel jacks?

I think the issue would be with Windows if it's not recognizing the Realtek audio codec and it's not disabled in BIOS. It's not uncommon with core hardware changes that a clean install is necessary. While it's not needed so frequently with just a CPU change you're actually changing from APU to CPU and discrete GPU and that entails a lot more core hardware all at once. You might consider resetting CMOS then doing a clean install of Windows so it recognizes all the hardware and installs default drivers at least.

Ok, not my first rodeo... been doing this a long time. I appreciate your suggestions, but I have done all those things... even got Microsoft involved at one point. In case you missed it, everything works perfectly with a Ryzen 3 2200G installed, but not with the Ryzen 5 2600. I'm pretty much convinced that the processor is faulty... I've just never seen a faulty processor manifest itself by disabling onboard audio! I'm probably going to try and pick up another 2600 on Ebay or somewhere and try it just to confirm the bad CPU.

With the Ryzen 5 2600 installed the Realtek audio chipset doesn't even show up in the Device Manager. I've done several clean installs and various BIOS versions.

But have you clean installed Windows...

But have you clean installed Windows...

Several times...

I just installed the 2600 CPU on an ASUS ROG STRIX B450-F Gaming motherboard and again, no audio chip detected. I think this conclusively proves that the error is in a faulty CPU.

Thank you everyone for your suggestions.

That's understood.

It conclusively proves nothing as Window's often uses different drivers and/or settings with different hardware. You have to clean out old drivers so that it can install new drivers and establish new settings sometimes. I just went through it with a printer my system that my system refused to recognize to install a driver for.

It can be done case by case, with some troubleshooting and sometimes even registry edits. But it's more often than not simply easier to do a clean install of Windows when making major core hardware changes to keep from chasing down gremlins in the future.

One thing...did you run DDU to completely uninstall all the AMD drivers set up for the 2200g...display and chipset... then run DDU to be sure the registry is completely clean? then install chipset drivers anew BEFORE installing the Nvidia drivers for the 1600? You should do that as a minimum, even if you do not clean install Windows.

I DID do a complete wipe and reinstall. I'm very familiar with the difference in chipsets and drivers between model number and manufacturers. I performed a clean install with the ASUS board and downloaded all the latest drivers.... still no audio chipset detected. I replaced the 2600 with a Ryzen 3 2200G and the audio showed up and worked instantly.

That does make it more conclusive.

FWIW: the audio chipset does connect direct to the CPU on AM4 platform; I'm not sure how exactly, probably using PCIe bus along with ethernet chipset. I once had a BIOS update 'kill' the ethernet chip on an AM3+ board I had...roll back BIOS and it worked, roll forward again and it stopped. So I do believe it's possible, just very very rare.
