Subject AW: AW: Audio with Hyper-V?
Date Mon, 19 Mar 2018 18:23:48 GMT

maybe there is a problem with audio & Hyper-V only and not with RDP in general. I tried
RDP on port 3389 to both the Hyper-V host as well to the same guest I tried to access via
port 2179, setting preconnection-blob (and security nla) – RDP to 3389 works with audio,
port 2179 etc. does not support audio.

I am particularly interested in connecting to 2179 as this allows to connect already before
the OS is loaded and irrespective of any network or remote access settings.

What next? Create an issue?

Thanks & Best Regards, Joachim

Hello Mike,

my setup is: Guacamole and the VM (Windows) I want to connect to are both guests on the same
Hyper-V host. The client I am using to connect to Hyper-V/VM via Guacamole is on a separate
physical machine, and I used the same client to test VMConnect.

In all my experiments, using VMConnect (on Win10 Pro) connecting to Hyper-V (also on Win10Pro),
Audio was working. 


Can you please confirm that:


1) You are connecting remotely (you are not trying to access the VM from the same machine
running Hyper-V).

2) Connecting remotely via some other RDP client also provides audio (not Guacamole and not
a client specific to Hyper-V like VMConnect).


I'm trying to eliminate the possibility that audio for Hyper-V only uses RDP for the remote
display (and deals with audio only by directly accessing the local sound card). Assuming it
does leverage RDP for both graphics and audio, I would then like to make sure that this is
not driven by some feature specific to Hyper-V which does not leverage the standard RDPSND
channel normally used for audio.
