Solution
The local site joins a
conference. No
audio, however, is
output from the
local display.
Perform an audio test to check
whether the problem arises at
the local site or a remote site.
If no audio is output from the
display when the audio test is
performed, it indicates that the
problem exists at the local
site.
The chair site has muted the
speaker of the local site.
If the volume of the display is
adjusted to the minimum value,
restore the volume to the default
value.
If the volume of the terminal is
adjusted to the minimum value,
restore the volume to the default
value.
If the audio cable is not
connected correctly or securely,
connect the audio cable properly.
