-------------------------------------------------------------
[~mjumper], Thanks for your reply.
Because the xfreerdp and the native Windows RDP client (mstsc) don't occur the
audio input issues, it seems that the Guacamole server (guacd) is doing
something wrong in the handling of RDP's "AUDIO_INPUT" virtual channel, just
like you.
That's, I think so, just like you.
When will this issue be fixed?

> 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:

> * 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.
