Bug Description

Just installed a new 11.04 Ubuntu on a new box. I can log in on the desktop, and sound works fine. "aplay -L" and "aplay -l" show lots of options. "mpg123 -a "hw:0,0" <song>" works great.

But I'm trying to make a headless server, that continuously plays music upon reboot. I don't want to log in.

Unfortunately, if I don't log in at the desktop (but instead from outside, via ssh), then there seem to be no alsa devices. /proc/asound/ shows lots of hardware detected, but "aplay -L" show no ALSA devices (except "null").

Similarly, if I log in at the desktop, but then log out again, all the alsa devices get destroyed. Or, if I log in, but then switch to a different user, that second user has no access to any valid alsa devices either.

I'm trying to make a script that will start up on system boot, and will continuously play music, hopefully with some special user id (= not me). How can I get all the software alsa devices to be generated at boot time, rather than per-user at desktop login time?
