Docker audio

[psychemedia]

Is it possible to also generate audio?

For example, would it be possible to run Audacity using dockergui?

Yes it is.

I managed to get so far but couldn't get the audio to work?

[hurricanehrndz]

To be honest it's been awhile since I have worked with this docker. I'm
going to rebuild it from the ground up, but I'm not sure when. I do
remember getting audio working but that was on a Linux box using a
pulseaduio sink. I might have done some forums post on it. I will try and
see if I can find some info. Which version of the docker Gui are you using?

I rebuilt my own image this morning from this repo, so I guess that would have reasonably recent versions of most things in it. (I'd also tried against hurricane/dockergui:xvnc).

Errors that spewed from the latest build include:

Never got audio on vnc only on xrdp

Ah.. ok - I was presumably using xrdp when I tested it - access via a browser; (screenshot was just a bit I'd pulled out where it was complaining!)

[hurricanehrndz]

When I refer to xrdp I mean the x11 server. Judging from the tag it seems
you are using the version that has xvnc as it x11 server.

I am way out of my depth on this - just a hopeful technologist trying to get things to run...

I note from looking at the guac-dev site that the packages have moved on from the ones used here (0.9.9 vs 0.9.6) and that docker support for guacamole was introduced, though I don't have a good understanding of what that means.

In my mind's eye, I'd (think) like to be able to fire up a guacamole container and then use docker-compose to link in an application container that would be exposed to a browser via the guacamole http endpoint. Or maybe it is better/simpler to keep to the current model and include a guacamole base image at the top of my own application container and let it wrap the application with the ability to view it over http in the browser?

[hurricanehrndz]

Yes that is totally possible. It will not help with the audio. You need to
look into x11vnc and figure out how to edit the configuration to support
audio. Like I said it is easier using the x11rdp server. Please look at the
tags on github and the commit history. There should be some mention of
audio.

Ah - right - just tried with hurricane/dockergui:x11rdp1.3 and it works, though the audio struggled at times (too much else running on my machine, possibly)!

Thanks for you patience.
