OK, I have found that PA inded does this (see the
src/pulsecore/resampler.c:calc_map_table() function).
Thanks!
It also explains my observations with special behaviour of the
Subwoofer/LFE channel - it is hardcoded for the LFE there).
It is apparently driven by the PA_RESAMPLER_NO_REMAP flag,
but I have to figure out where can I set this flag and whether it
can be done without recompiling PA.
