[K12OSN] Problem setting up sound for thin clients: ALSA instead of ESD?!

[john]

Hi all,

I am trying to set up LTSP to use ESD so that I can have sound on my thin
clients. However when I do:
esdplay /usr/share/sounds/phone.wav

I get the following message:

ja at ltsp:~$ esdplay /usr/share/sounds/phone.wav
ALSA lib confmisc.c:672:(snd_func_card_driver) cannot find card '0'
ALSA lib conf.c:3493:(_snd_config_evaluate) function snd_func_card_driver
returned error: No such device
ALSA lib confmisc.c:392:(snd_func_concat) error evaluating strings
ALSA lib conf.c:3493:(_snd_config_evaluate) function snd_func_concat
returned error: No such device
ALSA lib confmisc.c:1072:(snd_func_refer) error evaluating name
ALSA lib conf.c:3493:(_snd_config_evaluate) function snd_func_refer returned
error: No such device
ALSA lib conf.c:3962:(snd_config_expand) Evaluate error: No such device
ALSA lib pcm.c:2102:(snd_pcm_open_noupdate) Unknown PCM default
ALSA lib confmisc.c:672:(snd_func_card_driver) cannot find card '0'
ALSA lib conf.c:3493:(_snd_config_evaluate) function snd_func_card_driver
returned error: No such device
ALSA lib confmisc.c:392:(snd_func_concat) error evaluating strings
ALSA lib conf.c:3493:(_snd_config_evaluate) function snd_func_concat
returned error: No such device
ALSA lib confmisc.c:1072:(snd_func_refer) error evaluating name
ALSA lib conf.c:3493:(_snd_config_evaluate) function snd_func_refer returned
error: No such device
ALSA lib conf.c:3962:(snd_config_expand) Evaluate error: No such device
ALSA lib pcm.c:2102:(snd_pcm_open_noupdate) Unknown PCM default

So I am obviously using ALSA instead of ESD. My question is, how do I use
ESD? My lts.conf looks like:
[Default]
        SERVER             = 192.168.0.254
        XSERVER            = auto
        X_MOUSE_PROTOCOL   = "PS/2"
        X_MOUSE_DEVICE     = "/dev/psaux"
        X_MOUSE_RESOLUTION = 400
        X_MOUSE_BUTTONS    = 3
        USE_XFS            = N
        SCREEN_01          = startx
SOUND = Y
SOUND_DAEMON = esd
VOLUME = 75

Weirdly enough, doing ps aux | grep esd and
ps aux | grep alsa shows no sound daemons running.

Your wisdom would be greatly appreciated.

Thanks!

John
