It looks like set_input_gain on a speaker resets the one set in MCFG_SOUND_ROUTE.
For example in xmen.cpp, the ym2151 is MCFG_SOUND_ROUTE(0, "lspeaker", 0.20). k054321_device::propagate_volume() resets the input gain, overriding the 0.20

moo.cpp and rungun.cpp are affected too.
It can be worked around like this (xmen.cpp) but I don't like this solution, won't push it to git. k054321 needs refactoring instead.

#include "sound/flt_vol.h" upstairs
and at mconfig:

/* sound hardware */
SPEAKER(config, "lspeaker").front_left();
SPEAKER(config, "rspeaker").front_right();

FILTER_VOLUME(config, "ymsnd_l").add_route(ALL_OUTPUTS, "lspeaker", 1.0);
FILTER_VOLUME(config, "ymsnd_r").add_route(ALL_OUTPUTS, "rspeaker", 1.0);
FILTER_VOLUME(config, "k054539_l").add_route(ALL_OUTPUTS, "lspeaker", 1.0);
FILTER_VOLUME(config, "k054539_r").add_route(ALL_OUTPUTS, "rspeaker", 1.0);
K054321(config, m_k054321, "lspeaker", "rspeaker");

MCFG_DEVICE_ADD("ymsnd", YM2151, XTAL(16'000'000)/4)
MCFG_SOUND_ROUTE(0, "ymsnd_l", 0.20)
MCFG_SOUND_ROUTE(1, "ymsnd_r", 0.20)

MCFG_DEVICE_ADD("k054539", K054539, XTAL(18'432'000))
MCFG_SOUND_ROUTE(0, "k054539_l", 1.00)
MCFG_SOUND_ROUTE(1, "k054539_r", 1.00)
