Make sure on the GMA CONFIGURATION page that "MUTE
AUDIO ON TX" has a green box. Due to the closeness of the COM
antennas and high power of the COM transmitters, COM bleed‐
over may occur if this option is enabled. If the box is black,
highlight "MUTE AUDIO ON TX" with the cursor and press the
ENT key to turn the box green.
•
Reduce the volume of the item that caused the speaker to cut
out when turned up. A speaker protection circuit disables the
speaker output if the volume is too high. If the volume is not
sufficient, replace aircraft cabin speaker, reference the Cirrus
Maintenance Manual.

Reduce ICS Volume.
