BeagleBone Black P9 Audio Signals in MODE0

According to the BBB_SRM document page 86.  If I get into MODE0, will I get audio signals out to P9?

    This is the proper link for BBB resources: www.elinux.org/Beagleboard:BeagleBoneBlack

    On your question: Check the BBB schematic (can be downloaded from link above). McASP0 is on p.4. You will see that not all of the signals are directly exported to P9:
    Two signals are connected to other processor signals and you may need to either remove unwanted resistors or pinmux the other processor pin as input, so that it wouldn't interfere.
    Three signals drive the HDMI transmitter, so if you configure them to McASP you will lose HDMI.
