no sound until graphical login

[seamanjeff]

I have vlc 2.0.3 installed on Ubuntu 12.04 LTS.

When I start vlc (with -I http) from a terminal window via ssh, I don't hear anything until I log in at the GUI. If I log out in the GUI the sound stops, and then when I log back in it starts again.

Is audio somehow muted when I'm not logged in ? How can I work around this? I eventually want to disable the GUI entirely on this system.

This is what I see on the terminal:

Code: Select all

Well.. I just had to learn the bare minimum about pulseaudio. This was one of the rare instances where putting the pulseaudio server in system mode was the right thing to do. To do this I had to set PULSEAUDIO_SYSTEM_START=1 in /etc/default/pulse and set system-instance = yes in /etc/pulse/daemon.conf (and reboot).

To start vlc I have to su to a non-priveleged user and then use vlc-wrapper, which is a little backwards:

Code: Select all

su jeff -c 'vlc-wrapper -Z -R -I http --http-port 80 /usr/local/music'

Because this has to run at boot time.
