Jimmy commented on GUACAMOLE-1201:
----------------------------------
[~vnick], Thanks for your reply.
{quote}That's a valid point; however we still need to verify that the bug is
actually in the Guacamole Server code. When you say that xfreerdp works fine,
can you please confirm that the version of xfreerdp is *identical* to the
libraries used for guacd, or that you're running from the system running guacd?
Are there any other differences between where you're running xfreerdp and where
the guacd system sits - additional firewalls, latency, etc.?

Because I constructed the development environment in the same virtual machine
(VMware), I confirmed that the version of xfreerdp is identical to the
libraries used for guacd and that I'm running from the system running guacd.

> 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

> But I didn't get any solution and workaround.
>
> *Please let me know some solution or workaround to fix these issues.*
> Thanks.
