I wonder if the filter was embedded in the firmware of the CODEC's internal DSP (as it should) or simply done via software driver. For the latter it would mean the user would have to download the custom driver from the laptop manufacturer's website to get the fix as a generic driver would not have it. This would also mean that people using Linux distros on that laptop would not get the fix as well.
Though in this case the filter would not prevent crashes if the song was played externally, like from another device or over a PA system.
