Nick Couchman commented on GUACAMOLE-1009: ------------------------------------------ First, please start your request for help on the mailing list: http://guacamole.apache.org/support/ There are several audio issues that have been resolved in the git repo that should be released in the next version. Among them are the following: GUACAMOLE-732 GUACAMOLE-905 Please check if one of those issues resolves your problems with audio input - you can clone the git repo and check out either the master or staging/1.2.0 branch and build from there. > 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: > {noformat} > Apr 4 11:14:26
