AW: AW: Audio with Hyper-V?

[Joachim Lindenberg]

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.

Thanks,

Joachim

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.

If you're referring to a Guacamole extension, that subsystem is independent of 
the handling of audio. Your extension cannot be a cause.

Or can anyone confirm lack of Audio as well, indicating it might be an issue 
with guacamole?

 

Audio is a fairly fundamental feature within Guacamole that has been working 
for both RDP and VNC for some time. While it's not impossible that there is a 
bug here, it is very unlikely. [1]

 

Googling around regarding Hyper-V and audio, I find varying references to the 
level of support, with some stating that audio is not supported, while others 
state that audio requires some specific edition/version. Assuming that audio is 
indeed supported by Hyper-V, it's unclear whether it actually uses the audio 
aspect of RDP (the RDPSND channel) to provide this.

 

Can anyone confirm whether Hyper-V supports audio for RDP connections to the 
hypervisor? (For remote connections, that is, not connections via a tool 
running on the same local machine as Hyper-V itself.)

In all my experiments, using VMConnect (on Win10 Pro) connecting to Hyper-V 
(also on Win10Pro), Audio was working. Contrary, in none of my eperiments Audio 
was working with Chrome as browser and Guacamole as Gateway.

That helped somewhat! Syslog showed

Mar 13 21:44:34 ubuntu guacd[34423]: Failed to load guacdr plugin. Drive 
redirection and printing will not work. Sound MAY not work.

Mar 13 21:44:34 ubuntu guacd[34423]: Failed to load guacsnd alongside guacdr 
plugin. Sound will not work. Drive redirection and printing MAY not work.

Googling for that got me to:

 

 
https://sourceforge.net/p/guacamole/discussion/1110834/thread/76764d35/?limit=50

as one directory was missing I did a 

ln -s /usr/local/lib/freerdp /usr/lib/x86_64-linux-gnu/freerdp

and after that got

Mar 13 21:58:03 ubuntu guacd[34679]: guacsnd connected.

Mar 13 21:58:03 ubuntu guacd[34679]: guacdr connected.

In syslog.

 

Unfortunately sound is still not working and the virtual OS (still) indicates 
this with audio crossed out (“No Audio Output Device is installed”).

What to check next?

Thanks, Joachim

There is some work in progress on this:

https://issues.apache.org/jira/browse/GUACAMOLE-38
https://github.com/apache/guacamole-client/pull/181

I am trying to see if we can use Guacamole to provide RDP access for

Ideally, you would pre-configure the connections for these people so they
have access to only their specific computer(s) after logging in to
Guacamole, pull that information from LDAP / AD, write an extension which
dynamically derives these connections on a per-user basis, etc. Having an
input box which allows users to connect to any arbitrary machine is not a
precondition for having 700 users.

Unless these users truly need absolutely unrestricted access to everything,
I would instead recommend leveraging Guacamole's gateway nature and taking
a more principle-of-least-privilege approach.

Input box to type ip?

[michel.deschenes]

Hey,

I've been poking around but can't find anything on this..

Is it possible to display an input box so that the users can just type in
the ip (or FQDN) of the machine they wish to RDP to? I am trying to see if
we can use Guacamole to provide RDP access for roughly 700 people so they
can remote into their work computers if working from home.
