Comment (by hrubi):

 first of all you have to set correct PULSE_RUNTIME_PATH environment
 variable set (this is not documented as far as i know). on my system i set
 it to /var/run/pulse, can differ on your system.

 as i've looked in the code, pacmd is trying to send signal 0 to the
 daemon, to check if daemon is alive, then it tries to send SIGUSR2, so the
 module-cli-protocol-unix is loaded. none of these succeeds as you lack
 permissions to do that as an ordinary user.

 i've made a workaround for this via sudo, it's rather ugly, but it works:

 put these lines into /etc/sudoers

 {{{
 Defaults:<your_user>    env_keep=PULSE_RUNTIME_PATH
 <your_user> ALL=(pulse) NOPASSWD: /usr/bin/pacmd
 }}}

 then you can create some alias like this:[[BR]]
 {{{
 alias pacmd='PULSE_RUNTIME_PATH=/var/run/pulse sudo -u pulse pacmd'
 }}}


 i know it's just a weird hack, but it works for this time.
