Thanks Stuart,

I have same container in other server and it works great with other sound
device.

If I try the speaker-test, it fails:

$ speaker-test

speaker-test 1.2.4

Playback device is default
Stream parameters are 48000Hz, S16_LE, 1 channels
Using 16 octaves of pink noise
ALSA lib confmisc.c:767:(parse_card) cannot find card '0'
ALSA lib conf.c:4745:(_snd_config_evaluate) function snd_func_card_driver
returned error: No existe el fichero o el directorio
