Description Kevin Maximo 2005-06-19 21:50:37 EDT
Description of problem: No volume control elements and/or devices found Version-Release number of selected component (if applicable): How reproducible: Upon every log in and log out Steps to Reproduce: 1. Log in 2. Log out 3. Actual results: Just reports a pop up every time. Expected results: Just want to stop pop up Additional info: No sound card in machine or one that is supported - do not need sound just stop the error message.
Comment 1 Bob Chiodini 2005-06-23 07:07:54 EDT
This is a problem in FC3 also, even with a supported sound card. Oddly, gkrellm and the gnome volume control master control (left-click on the speaker icon) works correctly. Alsamixer also works correctly. Restarting the volume control applet causes the master control to disappear too.
Comment 2 Robert Nichols 2005-06-23 18:39:24 EDT
The problem is an out-of-date timestamp on /var/cache/gstreamer-0.8/registry-i386.xml . Just run /usr/bin/gst-register (as root) to fix it. The strange thing is that it's apparently st_ctime that is being checked, not st_mtime. When I tried restoring to a spare partition from backup tapes in an effort to see when the problem was introduced, gnome-volume-control worked just fine even though all the files were identical except for the st_ctime stamps. I consider that a bug. What's important is when the contents of the file changed, not when the file might have been restored from some old backup. All that was actually needed to make the volume control work again was "touch -ac /var/log/gstreamer-0.8/registry-i386.xml", which has the side effect of updating the ctime.
Comment 3 Kevin Maximo 2005-06-23 21:33:09 EDT
That did not cure it for me...
Comment 4 Bob Chiodini 2005-06-24 06:51:25 EDT
Running /usr/bin/gst-register restored the controls in the applet here. I had to restart the applet for the "master" (left-click) control to operate.
Comment 5 Kevin Maximo 2005-06-24 20:53:24 EDT
It does nothing for me. I don't have /usr/bin/gst-register. I have /usr/bin/gst-register-0.8 and I've run that but still no go. I don't want any sound item because I don't have a sound card that is compatible with anything. It's an ancient card. Others are getting this same error without having a card what so ever.
Comment 6 Kevin Maximo 2005-06-29 17:58:42 EDT
Just wish you could disable Sound altogether or even the hardware - to eliminate this message. Am I missing something somewhere as to why I do not have the file you mentioned to run but one similar with the -0.8 on the end???
Comment 7 Robert Nichols 2005-06-29 19:33:08 EDT
File /usr/bin/gst-register-0.8 is provided by the gstreamer package. File /usr/bin/gst-register is provided by gstreamer-tools. The two files are identical.
Comment 8 Kevin Maximo 2005-06-29 19:42:31 EDT
Ok just wanted to make sure I ran the right item. As I mentioned I did that but it did not resolve the issue. That same pop up message still happens upon every logon and logoff. As I said I shut off what I thought was all sound options I could find but it still didn't stop it from popping up everytime...
Comment 9 John (J5) Palmieri 2005-06-29 20:02:24 EDT
If you don't have the hardware you can always remove the sound applet from the panel and that should suppress the dialogs.
Comment 10 Kevin Maximo 2005-06-30 19:35:59 EDT
How do you go about doing that. I don't have any sound items on the panels. As I said I went through every preference I could find. I'm only a Linux novice but an Expert with computers and Windows. I've unchecked every possible thing I could dig up that had to do with sound. The pop up is still there. I have my linux box on a KVM switch and when I'm not even doing anything on that system but when I switch over to it I'll see two pop ups one about hardware and the other the one that I wrote this bug about.
Comment 11 Jim Caley 2005-07-01 14:44:29 EDT
I'd like to second Kevin's comments above. I freshly installed FC4 and have done no other work on it since, so I suppose a workaround would be to reinstall -- taking care to leave off any sound-related components -- but would rather just disable whatever it is that's causing this message. My box has no sound card, and I get the same pop-up he does upon login using Gnome. I have no sound applet in the panel. I also tried running /usr/bin/gst-register-0.8 with no luck. Neither esd or artsd is running.
Comment 12 John (J5) Palmieri 2005-07-01 15:38:34 EDT
It is most likely the applet starting up and exiting while throwing up the dialog. As a temporary solution try logging out and click the save current setup checkbox on the logout dialog. After doing that log back in to see if you get the error. I have to investigate this more and have it not throw up the error if you don't have sound hardware.
Comment 13 Jim Caley 2005-07-01 16:13:24 EDT
Yes, I tried checking the Save Current Setup checkbox (both for root and another user) when logging out but it didn't help; the pop-up still showed up on the next login. As a matter of fact -- and I don't know if this may be helpful or not -- as I tried your suggestion of logging in, closing the "No volume control..." pop-up, and then logging out with Save Current Setup checked, I had a warning come up about the user session lasting less than 10 seconds (no problem or surprise there), but *then* the "No volume control..." pop-up came up again -- presumably because the warning pop-up triggered a sound event. So my point is that whatever is generating the sound events apparently didn't go away after the first time I closed the "No volume control..." pop-up.
Comment 14 Kevin Maximo 2005-07-01 17:25:22 EDT
No that won't do it either, I actually do that after every single log off no matter what, always did that not know exactly what it was doing. As I said a linux novice. The error comes up twice on log on and once on exit. So during log in there must be two sound events or one for trying to load the hardware and one for the sound event it is trying to play. Both are the exact same error though. It's really no big deal but I think it does do something to performance when it happens and it's very annoying... LOL.
Comment 15 Ed Davis 2005-07-08 11:32:43 EDT
My situation is a little different. I've done a fresh install of FC4 (everything install). My system does have a soundcard. Sound works fine. I do not see the pop up "No volume control elemets and/or devices found" when I log in as root. When I log in a root the gnome volume controls work properly and sound works properly. The same is true if I log in as the user account created during FC4 installation. I have created a few more user accounts and all of these additional accounts get the pop up "No volume control elemets and/or devices found" upon log in. The sound works but the only way to control the volume is by using the knob on the speakers. The volume icon is not available for these additional accounts. Since I don't have this problem with root or with the first account I'm guessing this is a file permission thing. If I stumble upon a solution I'll post.
Comment 16 John (J5) Palmieri 2005-07-08 12:06:21 EDT
It does sound like a permissions problem. Can you give me the output of: ls -l /dev/dsp ls -l /dev/audio ls -l /dev/mixer Thanks
Comment 17 Ed Davis 2005-07-08 13:46:36 EDT
There is something strange going on with the permissions on those files. I changed them so that the problem goes away. Then on the next reboot and log in those file permissions are all messed up again and the problem comes back. Here are some file permissions from /dev crw------- 1 nub root 14, 3 Jul 8 05:01 dsp crw------- 1 nub root 14, 4 Jul 8 05:01 audio crw------- 1 nub root 14, 0 Jul 8 05:01 mixer If I chown root:root and chmod 666 it does not hold. It changes after reboot and log in. My problem is different than the others on this list. Everything works fine for root or the first user that logs in after a reboot. The second, third, etc users to log in get the pop up window. At first I thought it was everything worked fine for the user created during the FC4 install. That's not quite correct. Everything works fine for the first user to log in after a reboot.
Comment 18 Ed Davis 2005-07-08 14:22:05 EDT
I discovered one more thing. Everything is fine if the first user does Desktop -> Log Out before the second user comes to the system and logs in. To duplicate the problem log in a second user without logging out the first user. Applications -> System Tools -> New Login I'm not too worried about this bug. The workaround is to log out the first user from the console before logging in the second user. Most of the time this is no big deal, it just means the first user needs to close applications and save files before the second user can log onto the console and have volume controls. This is usually a minor inconvenience.
Comment 19 John (J5) Palmieri 2005-07-08 14:28:42 EDT
Ah, ok. So that is expect behavoir actually (well the applet shouldn't screem at you). When you log in all the permissions are switched to you and you grab the console lock. Anyone logging in after you can not grab the lock and can not steal permissions. If you log out you release the console lock and the next person is free to grab it and change permissions. In the future we want to change this but for now that is how it works.
Comment 20 Kevin Maximo 2005-07-11 09:54:35 EDT
Ok, I fixed my issue with this item. I Deleted all of my PANELS and simply re-created new PANELS. What I'm gathering is since the Volume Control is blowing up it does not show on the main PANEL on top of screen but that was the one that should of had the Volume Control on it. By Deleting the MAIN PANEL - the one that had all the icons on it - mine was on top of screen with applications, desktop, log in and out, and the task bar area with the RHN icon. I Deleted and rebuilt a NEW one and the error is now gone. This does not resolve the reason why it kept blowing up but it does stop the errors from popping up.
Comment 21 Tom Wood 2005-07-11 14:53:34 EDT
I get this same error on machines with no sound hardware. gnome 2.10 seems to expect to find sound hardware by default. And, with no decent way to edit the <blood-curdling scream>gnome registry<blood-curdling scream>, there seems to be no way except to delete the entire default panel as comment #20 stated. The RPM dependencies don't allow for reasonable removal of the multimedia packages responsible for this either. What's needed is a real registry editor for gnome, not gconftool-2, and/or a non-multimedia gnome core without all the unnecessary sound dependencies.
Comment 22 Kevin Maximo 2005-07-11 16:25:55 EDT
I just don't understand why I never had this error message pop up until I went to FC4, The Sound Icon or Volume Manager would always appear on all the previous releases from FC1 to FC3 on the panel and would not report error messages or blow up for that matter - but I am happy I ridded myself of those darn pop up messages - as I said I think it reduced performance also when this occurred as if in some kind of loop???
Comment 23 John (J5) Palmieri 2005-07-11 16:30:31 EDT
Most likely a bug in the upstream sources was introduced in GNOME 2.10. It could also be an alsa/dmix bug. I am still looking into the root causes.
Comment 24 Jack Tanner 2005-09-14 10:56:21 EDT
J5, any updates on this? Last comment is two months old. I also see this bug when connecting to an FC4 bugs via NX (set up per instructions at http://fedoranews.org/contributors/rick_stout/freenx/). I'm not forwarding audio, so the error message is understandable, but still annoying. A nicer UI would be something like the volume control icon in the panel getting a red slash through it.
Comment 25 John (J5) Palmieri 2005-09-14 11:26:14 EDT
This is fixed in Rawhide. I will look into fixing it for fc4.
Comment 26 David Childers 2005-10-23 01:12:55 EDT
Hi there. I am using FC3 with an Ensoniq sound card in a 700Mhz PIII. I have very similar symptoms. One thing that might be a clue is that when I open volume control preferences I see no audio channels available to control. I do get system sounds and I can hear streaming audio but when I try to listen to a CD there's no sound. The volume control is at minimum and when I try to move the slider up with my mouse it instantly snaps back to minimum with no change in sound level. Hope this helps. Thanks! /David C.
Comment 27 Jerry 2006-01-19 22:02:18 EST
I just got this error after an SELINUX relabel. On FC4. I have not had a wink of a problem with thi sbefore and i always use the volume control on the panel. Nw I can't get the panel volume control. Also gives the error when I try to add volume control to the panel and I tried the gst-register with no effect. SELINUX problem?
Comment 28 John (J5) Palmieri 2006-01-20 11:12:26 EST
if you /usr/sbin/setenforce 0 and then try to add the applet does it work?
Comment 29 Christian Iseli 2007-01-22 05:04:15 EST
This report targets the FC3 or FC4 products, which have now been EOL'd. Could you please check that it still applies to a current Fedora release, and either update the target product or close it ? Thanks.
