Alpine's pipewire-pulse binary is stripped (-a option removed); the only way to configure listening address is via config file. Add /etc/pipewire/pipewire-pulse.conf that overrides server.address to include tcp:4713 alongside the default unix:native socket. Server addresses now: - unix:native (for in-container clients) - tcp:4713 (for sibling containers connecting via PULSE_SERVER env var)
