Could you give more details?  The description is too concise and
vague.

The auto-mute feature is standard behavior.  When "Auto-Mute Mode"
control is set to "Enabled", the speaker is muted no matter what you
set the speaker mute switch.  If this isn't the case, please elaborate
what you expected and what doesn't work.
