Device redirection issue

Oliver.Zhan

In the guacamole When i remote access a win7 that is playing a music, but I can not hear the sounds.

 

But In the guacamole User's Guide document, it say that Audio redirection will be enabled by default.

 

Then I enable the Support audio in console , I still can not hear the sounds.

 

What is wrong? Please help me Nick.

If you connect from another RDP client on the same system that you're logging in with Guacamole, can you hear the sound?

Can you describe your Guacamole environment:
- Guacamole Client version
- Guacamole Server version
- FreeRDP version
- What browser you're using, including version

?
 

But In the guacamole User's Guide document, it say that Audio redirection will be enabled by default.


Yes, it will -you must explicitly disable audio support if you don't want it.
 

 

Then I enable the Support audio in console , I still can not hear the sounds.

It's best to address the entire community - this isn't my project or my mailing list, so best to include everyone.  There are many people who have fought with RDP Audio issues and Guacamole, so their experiences may be much more beneficial than my advice.

Hi Oliver:

We have had our own set of struggles with sound. As Nick mentioned the first thing to do is to ensure that sound works when using RDP client. If not, you should set the right policies on the Win 7: Gpedit.Msc.

Another problem you may be running into is this problem:


When I look at the Chrome console on the Chromebook, there is an error: app.js?v=0.9.13-incubating:3 The AudioContext was not allowed to start. It must be resume (or created) after a user gesture on the page. https://goo.gl/7K7WLu

Apparently Google has introduced a new "feature" that prevents autostart of sound - But it was rolled back in Chrome for a few months based on pushback. https://bugs.chromium.org/p/chromium/issues/detail?id=835767. So sound is working for now but we will need to develop a fix before the re-introduction of the feature. 


If you are using an iOS device, IOS prevents sound from playing automatically unless it is enabled by a user gesture: https://bitmovin.com/play-not-play-new-autoplay-policies-safari-11-chrome-64/

Hope this helps...
Antony

答复: Device redirection issue

Oliver.Zhan

I get it .my guacaomole install on the Ubuntu , when I open the debug info :

 

The error is :

freerdp_load_library_symbol: failed to open /usr/lib/x86_64-linux-gnu/freerdp/guacai.so: /usr/lib/x86_64-linux-gnu/freerdp/guacai.so: cannot open shared object file: No such file or directory

freerdp_load_plugin: failed to load guacai/DVCPluginEntry

 

I copy the guacai.so to the /usr/lib/x86_64-linux-gnu/freerdp/,    the sounds can be heared .
