Hi all good afternoon,
I'm still working with LTSP Server (edubuntu 14.04) and now we're facing
a new "problem", the audio on the thin clients that we're setting it's
not working, actually he is working, when we play a music from GUI it
works, but the problem and the scenario is that we need to send a file
'.wav' to play on the clients via networking, but it's not working at all.
We list all the packages installed on the machine and the PulseAudio
(apparentelly this is the guy to do this work) is installed and
"working" fine.

Also, we're facing a "module problem", we discovered that all the
modules that is working on the old server is not loading on this new one.
This is the output from the old server:
# lsmod | grep -i snd
snd_mixer_oss 22602 0
snd_seq_midi 13324 0
snd_rawmidi 30748 1 snd_seq_midi
snd_seq_midi_event 14899 1 snd_seq_midi
snd_seq 61896 2
snd_seq_midi,snd_seq_midi_event
snd_timer 29990 1 snd_seq
snd_seq_device 14540 3 snd_seq_midi,snd_rawmidi,snd_seq
snd 78855 5
snd_mixer_oss,snd_rawmidi,snd_seq,snd_timer,snd_seq_device
soundcore 15091 1 snd
We did the modprobe on every single module by hand but nothing. Also we
notice that on chroot enviroment (ltsp enviroment) we can't list the
modules by typing "lsmod", we got a strange error:
root@srvltsp:/# lsmod

But on the old-server it works fine:
root@srvbase:/# lsmod | grep -i snd
snd_mixer_oss 22602 0
snd_seq_midi 13324 0
snd_rawmidi 30748 1 snd_seq_midi
snd_seq_midi_event 14899 1 snd_seq_midi
snd_seq 61896 2 snd_seq_midi,snd_seq_midi_event
snd_timer 29990 1 snd_seq
snd_seq_device 14540 3 snd_seq_midi,snd_rawmidi,snd_seq
snd 78855 5
snd_mixer_oss,snd_rawmidi,snd_seq,snd_timer,snd_seq_device
soundcore 15091 1 snd
Another thing that we saw it was that on the old server (the thin
client) when we send the command # esdplay to play on this thin client
it works fine, and we notice during this procedure with the # top
command that the pulseaudio command appear, but and the new one no!
Has anyone have any ideia what it's going on? Any idea, help will be
appreciate PLEASE PLEASE!
And sorry about the size of mail.
Thanks!
