``position_fix=4`` is another combination available for all controllers,
and uses LPIB for the playback and the position-buffer for the capture
streams.
``position_fix=5`` is specific to Intel platforms, so far, for Skylake
and onward. It applies the delay calculation for the precise position
reporting.
``position_fix=6`` is to correct the position with the fixed FIFO
size, mainly targeted for the recent AMD controllers.
0 is the default value for all other
controllers, the automatic check and fallback to LPIB as described in
the above. If you get a problem of repeated sounds, this option might
