Ivan, thank you for your time and detailed answer.
I missed to tell you, that connecting with the official microsoft windows only rdp client the microphone gets redirected also with cristal clear sound. So i would guess, the rdp server can be removed from the list of the causing factors. Thank you! -----Ursprüngliche Nachricht----- Von: ivanmarcus <ivanmar...@yahoo.com> Gesendet: Freitag 10 April 2020 00:36 An: user@guacamole.apache.org; Karsten Nobis <karsten.no...@aeksh.de> Betreff: Re: Windows 10 + Guacamole 1.1 & 1.2 - microphone noisy connection Karsten, I don't have audio set on any of my instances, so can't speak with authority, but there's not been a great deal of complaint around the issue you describe with Guacamole that I recall. If what you're saying is that you can run an audio or video (with sound) file ok on the server and it plays at the remote end ok, but a microphone is distorted, then I suspect the problem will be at the server end. It could be a physical hardware issue with the microphone itself, or connection to the computer, or somewhere in the OS setup of the microphone audio path. If I were fault-finding this I guess I'd start by recording a microphone session at the server and playing that back to see if the issue was replicated. While you could do this remotely IMV it'd be better to first trial it physically at the server. Should that display the same problem then you'd need to go through standard fault-finding process at the server (reduce audio input gain, clean connections etc). If it were ok then I'd try playing the recording through the remote and following up from there. In essence it'd be a process of elimination. At this stage, without the benefit of further information, I suspect the only way Guacamole itself could be an issue would be if the server it's running on were maxed out in terms of resource, or there was a bandwidth issue - although I'd anticipate you seeing other symptoms were this the case?

I can hear sound sources from the windows 10 ltsc rdp server cristal clear - microphone is just a crackling noise and noise distorsions... Thanks in advance!
