Do you know how to do that.

I commented allowing audio access in the config file
 #lxc.cgroup.devices.allow = c 116:* rwm
I also did not creare the devices in /dev/snd in the container.
Now I can list the sinks and see all the audio cards in the container.

I still cannot play anything because it is suspended. There is some
improvement
I also commented in /etc/pulse/default.pa in the host and guest. It is
still suspended.
#load-module module-suspend-on-idle
