Is this on the host, the one with sound card?

I'm not sure what makes it that way, perhaps you set PULSE_SERVER on
the host as well? You shouldn't need that on ubuntu to play sound
locally.

You don't have to. The command doesn't even run on my container, yet
container sound works fine. "pactl list sinks", however, works
correctly, and shows the same sinks as on the host (I'm using
bluetooth headset).

# pacmd list-sinks
No PulseAudio daemon running, or not running as session daemon.

# pactl list sinks
