------------------------------------
Summary: RDP connection sound problems
Key: GUACAMOLE-228
URL: https://issues.apache.org/jira/browse/GUACAMOLE-228
Project: Guacamole
Issue Type: Bug
Affects Versions: 0.9.11-incubating
Environment: We've tried two servers:
1. The latest from https://hub.docker.com/r/glyptodon/guacd/
2. Checked out and built the last commit from
https://github.com/apache/incubator-guacamole-server
Both are showing the same problems.
Reporter: Kjell Otto
We're experiencing sound bugs when connecting via RDP to Windows 2012 R2 and
Windows 2016 Servers. We've followed all the steps necessary in order to enable
the sound and we're able to connect via Windows RDP without any issue. Connect
via RDP to a target PC and have the following settings in place:
Followed all the necessary steps gathered here:

Also, we've started the "Windows Audio" and "Windows Audio Endpoint Builder"
Service.
The problem is that weget both devices, input and output most of the time, but
they never work at the same time. The different behaviours we're experiencing
are the following. These are the quirks we've experienced and we would like to
help debug them:
1. On Windows Server 2016: Sound is only working once. It stops working when
one and exactly one sound was played and finished. When you play the test sound
for audio playback devices, it only plays the first sound on one side of the
headphones and then stops working completely. It will start to work for one
time again when you reconnect the session. If you open the Sound sesstings, we
don't see any amplitude for the "Remote Audio" microphone under the "Recording"
tab.
2. On Windows Server 2012 R2: We can play sounds just normally. Audio ouput is
consistent and working. Audio input is not working, same as for Windows 2016,
under Sound settings in the "Recording" tab, there is the "Remote Audio"
microphone without any amplitude whatsoever.
We've tried recording on both setups with audacity too, and with direct RDP
connections everything works as expected.
We would love to get feedback on this and are very willing to help in any way.
Please let us know how we can help.
