Hello,
As the title says, I have an MSI MAG B550 TOMAHAWK motherboard.
After installing the RTX 5060 and drivers in Windows 11, I've lost 99% of my sound. When I turn up the volume 3-4 times higher than I normally would,
I can barely hear the sound. The sound is very distorted, with crackling and buzzing noises.
My headphones are connected to the rear headphone jack of the motherboard, and the front panel of the case doesn't work (but I think I had it connected incorrectly from the start, so I disconnected it completely).
I should also add that I'm very careful with parts. I turn off the power supply or unplug the power supply cable when installing new parts.
I replaced the RTX 5060 card with my old one. That didn't help.

Unfortunately, this isn't a Windows issue, as I'm dual-booting, and Linux has the same issue. It's the same with a live Linux ISO.
Google Gemini suggested that a UEFI update might reinitialize the sound card, so I upgraded it one notch higher from version
7C91vAH file: E7C91AMS.AH0
to version:
7C91vAI file: E7C91AMS.AI0

It didn't help.
Assuming it can be fixed, Is there anything else I can do myself, or Is only the service center able to fix it?
Thanks in advance.

I thought you would like to try the latest BIOS 7C91vAK1...?
Never heard of similar issue that installing a dGPU could make the onboard audio bad, does your CPU have integrated graphics?
Did you accidentally damage the board or the trace around the audio chip when installing the RTX 5060?

I didn't want to jump to the latest UEFI in one step. (I have read somewhere that sometimes this can cause issues).

I forgoto to mention that this new card was inserted to the second PCI-e slot (one without metal reinforcement).

Do you know where on this image is audio chipset? I made few photos with not so good camera (only 13 MP).
And even with max digital zoom I couldn't find any visible scars or damaged elements. (Please ignore big black cube, that is misaligned. It was like that since day 1 when I bought it.)
But to be completely honest, so elements so super tiny. I probably wouldn't have been able to see it without 30x magnification.

Taking a totally different angle also from a hardware perspective. May be the pins of the rear headphone jack got disconnected from the motherboard; something soldering could fix.

Since I bought this board, I've only tried connecting the front audio panel once, and it didn't work. If you can give me any suggestions, I can try tomorrow, as it's already 11 PM here.

Keep us posted. Thinking down the same path we may also need to check whether the connector of the headphone its self has a loose connection. You could test this by hooking up the headphones to another source and hear whether it sounds properly or not. You could also test this by moving the wire near the plug while listening.

I just checked all the images and I don't see any damaged trace on the board.
Btw this one is the Realtek ALC1200 audio chip.
