The AMD ACP/ACP3X/ACP6x Audio Coprocessor I think is used to handle a digital microphone. The hardware is supported by kernel 5+, but it often seems to fail due to non-standard configuration by manufactures in specific machines, resulting in sound problems. These are fixed when identified by kernel "quirks" which identify the configuration in specific machines so that they work.

Hardware configuration is specified in the BIOS, so if the BIOS is passing the wrong information to the OS (ie Debian) sound will not work correctly. (It will work in Windows because the manufacturer has hacked the driver to make it work.)

This is my limited technical understanding anyway. In practical terms what you can do is to check that the BIOS is up to date (the manufacturer may have fixed hardware configuration specifications) and to try the latest Debian kernel from backports (it may have a quirk that fixes sound configuration on your machine).
