kernel configuration file:
device sound
device snd_gusc
Alternatively, to load the driver as a module at boot time, place the
following line in loader.conf(5):
snd_gusc_load="YES"
Non-PnP cards require the following lines in device.hints(5):
hint.gusc.0.at="isa"
hint.gusc.0.port="0x220"

DMA channel is C, set the flags to (C | 0x10). For a sound card without
the secondary DMA channel, the flags should be set to zero.
