Nick Couchman commented on GUACAMOLE-1009:
------------------------------------------
[~serverprogetti]: Version 1.2.0 has not been finalized or released, yet. If
you want to try out the code for 1.2.0, you will need to clone the git
repositories for guacamole-client and guacamole-server, and then build the
components. guacamole-client is built using the Java Development Kit (JDK) and
Maven, guacamole-server uses standard GCC compiler and make.
> RDP audio input not working on Windows10
> ----------------------------------------
>
> Key: GUACAMOLE-1009
> URL: https://issues.apache.org/jira/browse/GUACAMOLE-1009
> Project: Guacamole
> Issue Type: Bug
> Components: RDP
> Affects Versions: 1.0.0, 1.1.0
> Reporter: Ignacio
> Priority: Major
> Labels: audio
>
> 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:
