Modern design no longer use the hardware directly. For sound as well as for graphics. Developers use a library that uses a driver that plays with the hardware. FlightGear now use a library call OpenAL that brings us 3D positional sound and doppler effect to name a few. This is not just like playing a 22khz 8bits sample. It involves complex math on multiple channels. The library does its share of work and then assumes the driver is able to do the rest. And the RealTek driver is notoriously failing to do the right thing until recently. People told us they get the last driver available for their motherboard with no result. These drivers were released in 2002 and apparently far before RealTek managed to fix their software.
