Ignacio created GUACAMOLE-1009:
----------------------------------
Summary: RDP audio input
Key: GUACAMOLE-1009
URL: https://issues.apache.org/jira/browse/GUACAMOLE-1009
Project: Guacamole
Issue Type: Bug
Components: RDP
Affects Versions: 1.1.0, 1.0.0
Reporter: Ignacio
By using an RDP connection with the "_enable-audio-input_" feature enabled we
are able to see that the microphone is recognized on the remote machine as
"Remote audio" but the sound never reaches it. I mean, if we open the "Sound
settings", we don't see any movement (it always remains in gray) for the
"Remote Audio" microphone.
When trying to test the microphone the browser even asks for permission to
access it (and we give it).
We have tested the direct access from a Ubuntu bionic +without going through
guacamole+ and the operation of the microphone is correct with several versions
of freerdp:
- Freerdp from the ubuntu distro: (2.0.0~git20170725.1)
- Using nightly-builds (2.0.0-dev5 (f65c79ec5))
Our guacamole server is installed on a Debian buster, version 1.1 with freerdp
version 2.0.0~git20190204.1.2693389a.
We have enabled the debug in guacd and apparently in the logs everything is
fine and no errors are observed:

Tests done with both Chrome and Firefox (no errors in the console) give the
same result.
We have also tried an installation with guacamole version 1.0 and freerdp
version 1.1.0~git20140921 but no luck again.
