I installed Ubuntu Core 14.04 AMD 64. Now I want to play an audio! What exactly should be installed?! (I got this message on webkitgtk: jack server is not running or cannot be started)

I got this by run "lshw -short" command:

I'm assuming you have some embedded board and intend to plug in some USB Audio Class device to have it play audio?

JACK is a sound server that can be installed with the jackd package, if you didn't know that already.

Note that JACK is intended for professionals. If you didn't use JACK before and just want to play audio similar to what is used in the Ubuntu Desktop releases you should have a look at the alsa-base and probably pulseaudio packages to get things started (be aware of the dependencies that are being pulled in!).

The error message requiring "jack server" may just be misleading, as most applications should work fine with PulseAudio or ALSA alone.

Finally, I solved it!

We need only the alsa-base and gstreamer0.10-alsa packages.
