How manage volume remotely on pulseaudio

I am in the office with my computer ( Linux tumbleweed), and my kid of 3 years old iw in another computer showing videos.

Some videos are quieter and another are very loudness. With my first kid i do: 1)SSH as root 2)amixer and upper or lower the volume.

Now i cant a way to do with pulseaudio. I do 1)I do ssh as root successfully 2)

# amixer
ALSA lib pulse.c:242:(pulse_connect) PulseAudio: Unable to connect: Connection refused

# alsamixer
ALSA lib pulse.c:242:(pulse_connect) PulseAudio: Unable to connect: Conexión negada (Connection refused in spanish)

How i can control the sound volume? Thanks All

if i do sudo to the same linux user that is showing the video:

user @computer> amixer
XDG_RUNTIME_DIR (/run/user/0) is not owned by us (uid 1001), but by uid 0! (This could e.g. happen if you try to connect to a non-root PulseAudio as a root user, over the native protocol. Don't do that.)
ALSA lib pulse.c:242:(pulse_connect) PulseAudio: Unable to connect: Connection refused

Thanks all

Solution

  • After post on pulseaudio mailing list i found a cheaper way to do: Using PACTL tool.

    Set to 50% pactl set-sink-volume 0 32768

    Can use +10% pactl set-sink-volume 0 +10%

    Thanks to all. Christian
