Thanks Karsten,
I'd hoped that someone else with experience of Guacamole+audio might
have some wisdom but it doesn't appear so at this stage.
If I had physical access to my client machines I'd attach a microphone
or some other audio feed to the mic input to see if I could replicate
the issue. However I don't have such access presently, due to virus
restrictions in place (and I don't have M$ machines here).
FWIW it seems to me that you've got good resource on the Guacamole
server (particularly if a minimal number of users), but I'm still
unclear about bandwidth. In the absence of anything else to try I
suppose it could be worth tweaking the target machine redirected audio
quality, and checking the cpu load when using the microphone.

Hi,
the 1.1 server runs debian buster and guac is self compiled and the
webapp is a prebuild version from the website. 1.2 is totaly self
compiled.
The server is running on a Xeon Platform with 16 cores and 16gb of ram.
Cant notice any heavy load or errors in logfile.
Thanks!

Karsten,
It may well be that this problem will need someone more familiar with
how RDP audio is implemented within Guacamole than me, but either way
we'd need a bit more information I expect.
To that end could you let us know how you have Guacamole installed?
What is the OS, what is the hardware, how much resource does it have,
how did you install it?
Also, have you checked the (Guacamole) server load and bandwidth when
the issues occurs, and do you see any errors in syslog?

AW: Windows 10 + Guacamole 1.1 & 1.2 - microphone noisy connection
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!

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?

Hi,
I'm using versions 1.1 and 1.2 of guacd and webapp and when
passing through a microphone with chrome/firefox my audio
gets streamed very noisy and with interruptions.
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!
