this is typically a BIOS issue (Intel Management Engine not enabled in 
BIOS, or specific BIOS version has an issue). Re-enabling the ME in 
BIOS has often solved the issue (and sometimes a FW update is 
needed).

The DMI-based blacklisting is a bit iffy as this device does have digital
mics attached to the PCH, and with this patch, those microphones are then 
disabled for all users.
