How to access sound cart from LXC

How to send mp3 file to headphone jack from a LXC?

LXC:
I try "mpg123 MySong.mp3", but there is no snd devices
ls -1 /dev/snd
ls: cannot access /dev/snd: No such file or directory

ProxMox host:
ls -1 /dev/snd
by-path
controlC0
controlC1
hwC0D0
hwC1D0
pcmC0D3p
pcmC1D0c
pcmC1D0p
pcmC1D1p
pcmC1D2c
seq
timer

Yes LXC is a container, not a full virtualisation. https://pve.proxmox.com/wiki/Linux_Container I use the sound over pulseaudio or x2go. Both are working fine.
