Fails in a docker

[augnustin]

Has anyone tried to use this within a docker?

I get the following error:

ALSA lib confmisc.c:768:(parse_card) cannot find card '0'
ALSA lib conf.c:4259:(_snd_config_evaluate) function snd_func_card_driver returned error: No such file or directory

node: pcm_params.c:2286: snd_pcm_hw_refine: Assertion `pcm && params' failed.

According to the web this is related to the fact that the sound hardware is not connected...

I'll report along if I can make it work. Any suggestion welcome!

+1 leads to issues on Travis-ci.org as well

+1. Does anybody know the solution?

So I have a similar problem with this library, even if I just import the node-speaker it tries to open the default device. I would suggest moving this check into a specific function (open?)

So your docker container cannot find a output device the program will crash with your error.

If you want that the docker container has access to the sound card add --device /dev/snd:/dev/snd to your run command. See Runtime privilege and Linux capabilities
