Hi, I've been doing some strace on this and I found out that Java was trying to access some sound control devices and they weren't there.

Looking a little bit more I've found that it could be done by pulseaudio, I've installed it and looked good ( before I was having the same issue ).

Another thing is that the user that will start the tests must be part of audio group, eg:

audio:x:29:ubuntu,pulse

Shall I add this to Ansible scripts?

[smlambert]

Yes please update the Ansible scripts Allan, and thank you for looking into this.

[allandequeiroz]

Nice! Thank you @smlambert.

[neomatrix369]

@allandequeiroz Interesting the way you have debugged the issue out, can you share any resources or some writeup (in the form of a blog) on how it is done or how you did it, it will certainly help me and others understand and debug such systems.

[allandequeiroz]

Hey @neomatrix369 not anything fancy, the source is a guy that I worked with years ago.

Once I saw him using strace to see what was going on when he was executing one of our applications, how that was quite interesting.

What I did was just execute tests through strace. strace make test than traces and tests output started to appear in my terminal, when I saw the test failing I just stopped it and started to take a look, I've found some -1 EACCES (Permission denied) related to /dev/pts/*.

After that I googled for /dev/pts and found this page Man pts basically saying that a process try to open a channel to read and write data from/to a device through pseudoterminals.

At this point I was guessing that the problem could be something related to a lack of a "bridge" to application connect to a device or something like that, like the Display one, then I remembered about pulseaudio

PulseAudio is a sound server that is installed by default in most Debian desktop environments. It's main purpose is to provide a high level interface for controlling how multiple "sources" (programs that want to play sounds) are connected to "sinks" (sound cards).

I've decided to give it a try and I was luck.

@allandequeiroz That's some fine debugging :-)
