| 16:08 | <urly> Hi I have a sound problem. Clients don't speak. Tried bennybiy trick, anyway
| |
| 16:16 | vagrantc has joined IRC (vagrantc!~vagrant@freegeek/vagrantc) | |
| 16:19 | <urly> Hi vagrantc I followed the chan last days, about sound problem on clients. I tried the bennybiy solution but it didn't work. I'm a bit lost (google is quite mute, too)
| |
| 16:20 | <vagrantc> urly: what exactly did you try?
| |
| 16:22 | <urly> the -L module-suspend-on-idle line add in the initscripts client
| |
| 16:22 | ltsp-init-common script
| |
| 16:27 | <vagrantc> what distro?
| |
| 16:28 | <urly> ubuntu 12.04.2
| |
| 16:28 | server 64bits client 32 non-pae
| |
| 16:29 | <vagrantc> you ran ltsp-update-image after applying it?
| |
| 16:29 | <urly> yes
| |
| 16:30 | <vagrantc> are you able to get sound at all, or inconsistantly?
| |
| 16:32 | <urly> no sound at all, sound icon shows sounds mutes at first sound client occur. No sound at log neither.
| |
| 16:32 | at login I mean
| |
| 16:35 | urly_ has joined IRC (urly_!58b1a4bc@gateway/web/freenode/ip.88.177.164.188) | |
| 16:35 | <vagrantc> might just not be recognizing your sound card... are you sure the sound modules are loaded??
| |
| 16:36 | <urly_> no I'm not sure, but I think, what module? (and got freeze got to reboot now the urly one)
| |
| 16:37 | urly has left IRC (urly!58b1a4bc@gateway/web/freenode/ip.88.177.164.188, Ping timeout: 250 seconds) | |
| 16:43 | <urly_> snd used by 8 on the client
| |
| 16:46 | chipset via ac 97
| |
| 16:49 | client's built-in speaker works on ubuntu 10.04 LTSP
| |
| 16:53 | but not on 12.04
| |
| 16:54 | <vagrantc> might b ean OS driver issue
| |
| 16:56 | <urly_> ok what should I do?
| |
| 17:04 | <vagrantc> urly_: can you boot an ubuntu live image off USB stick or something? see if sound works?
| |
| 17:11 | vagrantc has left IRC (vagrantc!~vagrant@freegeek/vagrantc, Ping timeout: 240 seconds) | |
| 17:18 | vagrantc has joined IRC (vagrantc!~vagrant@freegeek/vagrantc) | |
| 17:20 | <urly_> trying right now, issues with ubuntu pae, loading lubuntu...
| |
| 17:36 | 7 0 0 MHz + 2 5 6 Mo is not fair
| |
| 17:41 | <vagrantc> ?
| |
| 17:42 | <urly_> freeze reboot reload... but when I launched audacious, notifier didn't seem to show any break, I am retrying

| 17:48 | <urly_> sound works (nice) on lubuntu 12.04 32bits liveUSB
| |
| 17:48 | <bennabiy> Someone having sound issues?
| |
| 17:50 | <urly_> Yep bennabiy, without your 'luck'
| |
| 17:51 | <bennabiy> what distro?
| |
| 17:51 | <urly_> ubuntu 12.04.2, server 64bits, client 32bits non-pae (linux-generic)
| |
| 17:53 | <bennabiy> Are you able to get any sound on the clients?
| |
| 17:54 | <urly_> right now with lubuntu live usb yes, but
| |
| 17:55 | with ltsp no, sound seems to break when some sound client start
| |
| 17:55 | no sound at greeter neither
| |
| 17:57 | eg ubuntu sound test or firefox youtube html5 test makes mute the sound icon notifier
| |
| 17:58 | and modules unload themselves as well
| |
| 18:03 | <bennabiy> Can you pastebin your /opt/ltsp/i386/usr/share/ltsp/ltsp-init-common
| |
| 18:04 | <urly_> sorry I've never.. howto?
| |
| 18:05 | <vagrantc> !pastebin

| 18:11 | <bennabiy> urly_: do you have a command shell on the local machine set up?
| |
| 18:11 | !SCREEN_02
| |
| 18:11 | <ltsp`> SCREEN_02: To get a root shell on an Ubuntu thin client: https://help.ubuntu.com/community/UbuntuLTSP/ClientTroubleshooting#Using_a_shell_SCREEN

| 18:12 | <ltsp`> Admin, Channel, ChannelLogger, Config, Factoids, MeetBot, Misc, Owner, RSS, Seen, Status, Time, User, and Utilities
| |
| 18:12 | <urly_> ok I leave lubuntu liveUSB and restart LTSP client now until screen 2
| |
| 18:13 | <bennabiy> If you set up your lts.conf to enable the shell screen, I can walk you through how to manually restart your audio, and see if that fixes it temporarily
| |
| 18:15 | <urly_> I see, client booted
| |
| 18:15 | I've got a root account on screen 1, good?
| |
| 18:17 | <bennabiy> yes
| |
| 18:18 | do you know if you have a text editor installed in your chroot?
| |
| 18:18 | <urly_> vi I guess
| |
| 18:18 | <bennabiy> Are you comfortable with vi?
| |
| 18:18 | <urly_> more middle yes than middle no
| |
| 18:19 | <bennabiy> Ok.
| |
| 18:19 | so vi /sound.sh
| |
| 18:20 | <urly_> sound.h in root new file opened
| |
| 18:21 | sorry /sound.sh new file
| |
| 18:21 | <bennabiy> good
| |
| 18:22 | I will make a pastebin for you to copy from, so I do not flood the room with text
| |

| |
| 18:23 | but before you run this script, we will have to clobber the current pulseaudio session
| |
| 18:24 | on the client shell
| |
| 18:24 | ps -ef | grep pulse
| |
| 18:24 | look for the entry that has pulseaudio --system
| |
| 18:25 | tell me when you are caught up
| |
| 18:26 | <urly_> no pulse thing (no user logged...)
| |
| 18:26 | <bennabiy> log in a user
| |
| 18:27 | Now do you have a pulse session?
| |
| 18:28 | <urly_> I log before pasting or after?
| |
| 18:29 | <bennabiy> You can make the script, and then log in
| |
| 18:29 | two different systems at this point
| |
| 18:31 | <urly_> yes and some more ps grep pulse
| |
| 18:32 | <bennabiy> Actually, you can also make this change for the sake of having a log... vi /usr/share/ltsp/ltsp-init-common and add in after the --system -vvvv and for the --log-target=syslog change it to --log-target=file:///pulse-debug.log
| |
| 18:34 | What that will do is enable debugging logging, and log all output to the root directory of the chroot, where you can copy it to the home directory of the logged in user if you need to access it.
| |
| 18:34 | after you do that, go ahead and clobber the pulseaudio session on the client
| |
| 18:39 | <urly_> ok 1) I kill the ps id of pulse ? 2) I hope you will tell how to catch the logs between systems
| |
| 18:42 | <bennabiy> yes
| |
| 18:42 | the pulse which has the --system
| |
| 18:43 | You should see an bash entry, a pulse entry and your grep search
| |
| 18:44 | tell me when it is killed
| |
| 18:44 | <urly_> ok ps with blablabla pulse blablabla killed, user connection killed
| |
| 18:45 | it was a ssh blabla pulse ... no more pulse entry
| |
| 18:46 | <bennabiy> Hmm, sounds like you killed your user session
| |
| 18:47 | you should look at the client syslog and see if something prevented the pulseaudio from starting in the first place.
| |
| 18:49 | <urly_> ok, ... how ? (never done the log things, but really want to)
| |
| 18:49 | <bennabiy> less /var/log/syslog
| |
| 18:49 | type "/pulse" and press enter
| |
| 18:50 | it will search for the term pulse
| |
| 18:50 | you can press n to go to the next instance
| |
| 18:51 | <urly_> allright, pulse events
| |
| 18:51 | Parker955_Away is now known as Parker955 | |
| 18:52 | <urly_> may I pastebins?
| |
| 18:52 | <bennabiy> sure

| 18:58 | <urly_> http://pastebin.com/nqVaUpEF
| |
| 19:02 | <bennabiy> hmm. did you log your user back in?
| |
| 19:02 | <urly_> yes
| |
| 19:02 | <bennabiy> ok
| |
| 19:03 | do you see a /usr/bin/pulseaudio ps entry?
| |
| 19:03 | should be with the user pulse
| |
| 19:04 | possibly root
| |
| 19:06 | <urly_> ps -f g| grep pulse doesn't say /usr/bin/pulseaudio, only ssh and grep
| |
| 19:06 | <bennabiy> ok, did you make the changes to ltsp-init-common?
| |
| 19:06 | Phantomas has left IRC (Phantomas!~Phantomas@ubuntu/member/phantomas, Quit: Leaving.) | |
| 19:07 | <bennabiy> if so, then do a chmod +x /sound.sh
| |
| 19:07 | then /sound.sh
| |
| 19:07 | <urly_> I did your -L change in ltsp-init-common
| |
| 19:07 | wait sorry my user is not in -G audio, should he?
| |
| 19:08 | <bennabiy> Nope, should be in the pulse-access group
| |
| 19:09 | If your user is in audio, you can clobber permissions on the server potentially
| |
| 19:11 | <urly_> ? I give the group audio or pulse-access to user?
| |
| 19:12 | <bennabiy> pulse-access
| |
| 19:12 | not audio
| |
| 19:12 | audio gives the user control over the actual hardware, which means you would be able to output sound to the server, rather than your client
| |
| 19:13 | in LTSP, the client machine is actually the audio server, and the server is the client
| |
| 19:13 | <urly_> user added, and ok... very good
| |
| 19:13 | <bennabiy> ok then type /sound.sh
| |
| 19:14 | after doing the chmod I listed above
| |
| 19:14 | then do a ps -ef | grep pulse
| |
| 19:14 | and see if you have a new listing
| |
| 19:14 | Parker955 is now known as Parker955_Away | |
| 19:16 | <urly_> I have some
| |
| 19:18 | <bennabiy> test if you have sound
| |
| 19:20 | <urly_> no sound, I relog my user?
| |
| 19:21 | <bennabiy> Can you pastebin your current ltsp-init-common again?
| |
| 19:25 | <urly_> http://pastebin.com/jARu7xAk
| |
| 19:32 | <bennabiy> can you list the /usr/bin/pulseaudio process?
| |
| 19:36 | vagrantc has left IRC (vagrantc!~vagrant@freegeek/vagrantc, Ping timeout: 268 seconds) | |
| 19:37 | <urly_> no such ps
| |
| 19:38 | vagrantc has joined IRC (vagrantc!~vagrant@freegeek/vagrantc) | |
| 19:38 | <urly_> I do /sound.sh and then there is one on tty1
| |
| 19:39 | <bennabiy> can you output it?
| |
| 19:39 | the whole ps entry for it
| |

| |
| 19:45 | <urly_> http://pastebin.com/Rtabtt7X
| |
| 19:47 | <bennabiy> You should check your audio now..
| |
| 19:47 | otherwise, you might try going to #pulseaudio and posting your log there, and see if there is any wisdom...
| |
| 19:47 | It looks like your user should have audio now
| |
| 19:49 | <urly_> no sound and ps disappeared
| |
| 19:51 | <bennabiy> Are you trying to log out and log back in to test, or all while logged in?
| |
| 19:51 | <urly_> all while logged in, You want I dis-re-log?
