> I found some audio input issues when using Audacity and Adobe Audition.
> The test environment follows as below:
> * *FreeRDP*: stable-2.0
> * *Apache* *Guacamole* *Server*: staging/1.3.0
> * *Apache Guacamole Client*: staging/1.3.0
> * *Remote Server*: Windows 10 64 bit Version 2004 (OS Build 19041.572)
> * Ubuntu 18.04 64 bit
> * Audacity 2.3.3
> * Adobe Audition 2020
>
> The test case follows as below:
> # Connect to the remote server (Windows 10, 64bit) over the Apache Guacamole Client.
> # In the remote server, run Audacity.
> # In Audacity, click the record button and start to record the audio.
> # In Audacity, after 10 seconds, click the stop button.
> # In Audacity, click the play button.
>
> In step 5, we can see the following issues:
> # The recording time is 10.5 seconds, but the actual recorded time is about 7.5 seconds. (see 'audacity-recorded-time.png' image.)
> # The recorded audio has a lot of noise.
> FYI: When using Adobe Audition, the crash issue frequently occurs. (see 'adobe-audition-crash.png' image)
>
> The weird things follow as below:
> * When performing the above test case by using xfreerdp (2.2.0, c72055d74), we can't see the above two issues in Audacity.
> * When performing the above test case by using mstsc (10.0.18362), we can't see the above two issues in Audacity.
> Especially, when using the Apache Guacamole Server & Client, we can't see the above two issues in Microsoft Voice Recorder. (see 'ms-voice-recorder.png' image)
>
> For these audio input issues, I researched the followings:
> * [http://apache-guacamole-general-user-mailing-list.2363388.n4.nabble.com/audio-support-in-RDP-td7508.html]
> * https://issues.apache.org/jira/browse/GUACAMOLE-236
> * https://issues.apache.org/jira/browse/GUACAMOLE-228
> * [https://jira.glyptodon.com/browse/GUAC-1511]
>
> But I didn't get any solution and workaround.
>
> *Please let me know some solution or workaround to fix these issues.*
> Thanks.
