Michael Jumper commented on GUACAMOLE-228:
------------------------------------------

I don't think this is resolved, is it?
{quote}
It is.
RDP audio input does indeed work on both Windows Server 2012 and 2016, thus the
bug as originally reported is invalid. The cause of the issue turned out to be
configuration (more on this below). It may be worth noting in the
documentation, but the issue is nevertheless not a bug and is independent of
Guacamole.

At least there should be something in the documentation that says you have to
use https for it to work on Chrome
{quote}
Documenting that some browsers may require HTTPS for audio input would be
reasonable. If you'd like to open an issue for that, please feel free to do so.
{quote}
... Also, the default setup is not https so the browser with the biggest
marketshare right now won't work for RDP audio input.
{quote}
No, there is no such default setup. Whether HTTP or HTTPS is used is completely
independent of Guacamole; it's a configuration detail of either the servlet
container (usually Tomcat) or the reverse proxy in front of the servlet
container (like Nginx or Apache).

On the speedup: How could I test that, any hints on how to check this?
{quote}
I've opened a separate issue for the incorrect recording rate: GUACAMOLE-236
I don't have any hints on checking whether my theory is correct at the moment,
but the above would be the place for the discussion on that point to continue.
We'll know more as that issue progresses.

> We're experiencing sound bugs when connecting via RDP to Windows 2012 R2 and

> - enable-audio-input
> Also, we've started the "Windows Audio" and "Windows Audio Endpoint Builder"
> Service.
> On Windows Server 2012 R2 and Windows Server 02016, if you open the Sound
> settings, we don't see any amplitude for the "Remote Audio" microphone under
> the "Recording" tab. We've tried recording on both setups with audacity too,
> and with direct RDP connections everything works as expected.
> We would love to get feedback on this and are very willing to help in any
> way. Please let us know how we can help.
