In the Guacamole GUI there's a tickbox 'disable audio'
You could also check this out:
http://guacamole.apache.org/doc/gug/configuring-guacamole.html
which explains how the audio works (and from that perhaps how you might
deal with it in your configuration).

Hi
I agree to we can not send u un- encrypted traffic for checking but as
per discussion I ask you how to check at guacamole end if audio is
enabled? And if enabled then give me solution for disable the audio
streaming

Hello Mike,
We have investigate further and there in we found that there's
an continues ACK/SYN/PING traffic flows between server and
client for an absolutely idle session.
Yes, this is by design - the Guacamole protocol has built-in
mechanisms to verify that the connection is still active and
prevent the server (guacd) from dropping the connection. However,
as Mike stated, the amount of traffic generates solely for keeping
alive an idle connection is very low - 17Kb/s - so it does not
account for all of the traffic you are seeing - something else is
going on.
Due to which number of packets and in turn data exchange
increases continuously for an absolutely idle session.
Absolutely idle is a little bit of a misnomer, here. If a session
is in progress, it will *never* be "absolutely idle" - that is,
there will always be some amount of minimal data exchange in order
to keep the session alive - else it will shut down. This is true
of pretty much any protocol - RDP, VNC, SSH, Telnet, and Guacamole
- all will have some minimal amount of overhead client/server
traffic even when there are no mouse/keyboard actions and the
screen is not being updated.
Can you please guide us on how to stop continues server
PING/NOP/ACK/SYN ?
No, this cannot be disabled without changing the code, and the
result would be undesirable - the remote connection would shut
down. And, this isn't a problem - again, the amount of data
you're seeing shows that something else is going on aside from a
completely idle connection. You might check and see if audio is
being generated that would account for the higher bandwidth
utilization, or if file sharing is enabled.
And, as Mike said, in order to truly debug what's going on, here,
you need to look at the traffic un-encrypted. This will allow you
to see the actual Guacamole protocol packets that are being
exchanged and figure out where the data is coming from.
