before pull, there is a ros:kinetic-robot image, which is based on ubuntu, and then hang up the previous ALSA playback wav code to execute
.docker run -it \
--device /dev/snd:/dev/snd \
-v /media/dyan/project/projects/voice/:/data/voice/ \
ros:kinetic-robot
error occurred when playing audio. There was a problem when opening the sound card device
ALSA lib pcm_dmix.c:1029:(snd_pcm_dmix_open) unable to open slave -sharpsnd_pcm_open()
cannot open audio device default (No such file or directory) -sharperr_num=snd_pcm_open()snd_strerror(err_num)
looked at some related problems run apps using audio in a docker container
but still cannot be solved.
in the container apt search alsa
, there is a library of alsa, and the code can also be compiled in the container.
root@72b53ba14730:/-sharp apt search alsa

I don"t know what the problem is. Is there something wrong with the device mapping?
