Restricting the IntelHDA PCI match to subclass 0x03 (e0c02f7) hid the
speakers on modern laptops, where the same HDA controller enumerates
as 0x01 (Multimedia audio controller) when the Smart Sound DSP is
enabled. Match any multimedia subclass instead; legacy AC'97 devices
also report 0x01 but expose an I/O-space BAR0, which Probe already
rejects via the ReadBar0 check.
