You're correct. Realtek's vendor ID is
10EC for PCI bus connected devices. (Numbering is different for USB. see below) So, absolutely, that's your Realtek audio h/w. Your problem is: Windows can't find a Windows 11 driver for any of the hardware IDs. But it did find a driver that matched one the device's
Compatible IDs (you can use the Driver Details pull down menu to also see Compatible IDs)
Hardware IDs uniquely identify a specific device for precise driver matching, while Compatible IDs are general identifiers used as a fallback if no specific driver is found, allowing devices to use generic drivers. Hardware IDs offer full functionality, whereas Compatible IDs prioritize compatibility, often allowing for a single generic driver to handle broad classes of devices. Manufacturers choose the IDs to program into their various devices. That's how they tell Windows which drivers it can choose. When multiple drivers match, Windows has an algorithm choosing best match (e.g. h/w id matches are always chosen over compatible id matches)
In your case, Windows could only find a driver match for the Realtek device using one of it's Compatible IDs. When no hardware or compatible ID matches, you have a no driver found problem. When there's a driver match, Device Manager displays the device name found in the driver file. Good guess! In your case, it used the name it found in the Windows driver. When the device name in DevMgr doesn't indicate manufacturer, you can only be certain finding its h/w id and looking up the vendor id
Two footnotes:
- When there's no driver match, Device Manager displays the device with an error icon. In this case, Windows displays whatever name the mfr put in the Device Descriptor. That name is only replaced if a driver found.
- You can lookup a mfr name based on a device's vendor ID using a tool like Device Hunt. Note the vendor ID in a USB devices has a VID prefix, not VEN
Glad you at least got sound working!
