# Surface Pro 11: reconstructing native Linux audio behavior

> SP11X1e-audio reconstructs Surface Pro 11 speaker and internal microphone behavior on Linux from Windows runtime observations and binary analysis. Its patches and AudioReach topology address SoundWire amplifiers, LPASS microphone clocks and capture routing; reproduction scripts rebuild the accepted topology and kernel artifacts.
