IC04
Audio switch, main L/R or AV4 (components input) L/R. main L/R comes
from MSP3410 audio switch.
IC05
Video switch, Front video or AV4 (in case of YCbCr normal components),
which is connected to TDA9321 for sync separation
IC06
Audio switch, Centre sound or AV4 (components input) L/R. Output goes
to IC04 to switch another audio input.
