pactl is the same in the host and the lxc

but when I type *pacmd list-sinks* on the guest I get only the dummy card
I do not get the long list of cards that I get on the host. That is the
problem. Is there anything else that I am missing. It seems that the
connection is correct, but the device list is not passed to the guest.
