Ubuntu Multimedia :: Lucid 10.04 No Sound As Normal User / But Sound OK As Root
May 1, 2010
I've got a custom compiled kernel, just built on Lucid 10.04 from the kernel sources.System works fine, except for sound.When I log in as normal user and try to play a wav file using.The sound file is being played, but I hear no sound.However, when I do "sudo -s" and become root, execute the same mplayer command then I can hear the sound.My Sound preferences shows no input device and only "Dummy Output" as output device.On the generic kernel as came with the Lucid 10.04 CD, sound preferences shows different devices.The strange thing is: when I compiled my custom kernel, I changed nothing to the sound options in the kernel config file.
I cannot find a post that matches this scenario...the id created during the install (from CD) of Karmic has fully usable sound. However, users created from the Users and Groups app do not.
I have made sure that all users are defined to the audio, pulse, pulse-audio, and pulse-rt groups. No luck.
I have followed every step I have read having to do with the alsamixer. No luck.
I have verified that alsa and linux itself are at the latest versions.
If sound on F12 works as root user but not as a normal user, try this simple fix! I've been struggling to get sound working as a normal (non-root) user since F10. Until now I've had to run X as root user to get any sound out of my machine.
Sound actually works OK now for me as a normal user. Here's how I fixed the problem.
First I uninstalled pulseaudio with:# yum remove pulseaudio Then reboot back to the hardware. You might want to keep pulseaudio, but I have no need for it. PA wasn't running on my system anyway.
Running X as root user, I did the following: As a test I opened a root shell and typed the following:
[root]# alsamixer c0 That started the alsamixer OK, and all the controls were accessible.
I have installed Fedora 10-x86_64. I was happy and content with the distribution. Earlier, I found that there is no sound on my headphone's jack where as the normal sound output from my laptops's speakers is OK. I fiddled with the available mixers but couldnt get anything. There seem to be 5 different mixers (HDA, ALSA, OSS), 3 for the playback and 2 for the capture.
I am using an acer 4530 laptop. It has a nvidia Nforce MCP77 chipset. and the o/p lsmod| grep snd :
I have a laptop DELL Latitude D600. The sounds works great and I can control it with the laptop buttons (increase/decrease/mute volume).
I just upgraded to Ubuntu 10.04. In prior versions, I could control independently the volume for the speakers and for the headphones. And I was able to "join" them together so that when I increase the volume, it increases in both.
Now in 10.04 I can't find where to join them. But that's fine. The problem I have now is that the volume for the headphones seems to be a 10x multiplier of the "master" volume. For example, in order to hear "normal" on the headphones, the master volume has to be almost on mute. If I increase to 1/4 of the way out, the sound is too loud for a human being.
I went to alsamixer to see what's going on and started with everything at 0.
So I put my mouse on top of the volume control on the taskbar and with one "click" on the wheel (to increase volume) I get this code...
That's just one 'click' of the wheel... and the volume control shows almost nothing on the volume bar (the tooltip says Output: 5% -75.70 dB.
In the past the 5% gain in the output was proportional for the headphones. But now it's multiplied by a lot. This makes the volume control useless when using headphones. I have to go to alsamixer to adjust manually.
And to top it off, the new Ubuntu doesn't have the "old" volume control where you can see the level of each output element.
I installed Slackware 13 in VirtualBox 3.1 (seehere)When I'm logged in as a normal user, I get a mesage that Intel *** (sound device) doesn't work anymore and I hear no sound.But it works very fine when I'm logged in as root.
I used to listen music and watch films with my with my laptop but, after an upgrade (to 10.04 lucid) it is impossible to hear any sounds. The sound card is detected and it works since making the laptop boot from live CD (of ubuntu 10.10) I get sounds without problems. I tried to reinstall alsa-base and alsa-utils with no results. Everything looks OK, but the sound! (It's not muted!)
I just installed Ubuntu Lucid beta 2 on my desktop, and I can't seem to get the sound to work. I have a Soundblaster Audigy 2 card and the motherboard has built-in sound, but ubuntu doesn't recognize either of them. The only hardware option I have in my sound preferences is for SPDIF, and thats the only thing that shows up in alsamixer as well.
I get no sound for anything, I am running Ubuntu Lucid-amd64. Pulseaudio detects my sound card, and appears to be playing to it when I look at pavucontrol. But I get no sound for anything, not even alerts. I don't eve know how to debug it, because everything I have looked at looks like it should be working. I have checked every mute button I can find, and nothing is muted that I can see. The relevant information for my sound card from lspci -v is:
The title pretty much says it all, the sound on this system was working fine until I ran the upgrade to Lucid. I've tried everything in the standard troubleshooting guide, the sticky threads and plenty of forum searches but so far I've come up with nada. For some reason Ubuntu refuses to see my soundcard, no matter how much I twist and tweak it. It's an Asus M3A78 motherboard with an on-board Realtek ALC1200 chip (snd-hda-intel). Here's most of the relevant output, hopefully someone can easily spot what's going on because I'm getting snow-blind staring at the monitor. code...
So i upgraded to 10.04 a few months ago, right after it was released. clean install. it worked perfectly out of the box, or so it seemed. I had had sound problems in 9.10 that i didn't experience after i upgraded... until i tried to use some headphones a few days ago. when i connected the headphones, the speakers wouldn't mute. i thought it was no big deal. i had the same issue in 9.10 and it was fixed after i upgraded alsa. i figured i'd try the same thing. I used the same alsa upgrade script i used last time [URL] and it fixed the jack sensing and the sound worked perfectly... for about 5 minutes. after a short while of playing audio, sound would stop playing. i'd stop getting sound from video files, audio files, and even from my browser. i'd have to reboot to get sound again... only to lose it again in about 10 minutes. Now it's regressed to the point where i have no sound even after i reboot.
weird thing is, when i test out an audio file with aplay, it works... even if i just get garbage sound from some mp3 files.
anyway, i've got an HP dv7 and this is my aplay -l output
Code: sleepee@sleepee-laptop:~$ aplay -l **** List of PLAYBACK Hardware Devices **** card 0: Intel [HDA Intel], device 0: STAC92xx Analog [STAC92xx Analog] Subdevices: 1/1
My sound in Lucid was working fine (for months), and then, for no obvious reason, it stopped working today. I get no sound from any application. I have no idea what could have changed on my system to cause this.When I re-boot Lucid, the login sound plays, and sound works briefly, but it always stops eventually after I login.I am overwhelmed by the large number of different Ubuntu sound problem fixes
I can't get sound to work and am not sure how to trouble shoot. The sound DOES work when first booting, and I can make it play a test beep with the sound config app. But I cannot get sound from any other application. One possibly relevant fact is that I see a lot of I/O errors early in the boot process, but they flash by quickly so I cannot quote them.
Upgraded via Update Manager from 9.10 sound-previously-working-just-fine-system. Now, for example, running any audio-producing app (Rythmbox is a good example but its the same for anything including out of a VirtualBox XP install or with MythBuntu): The main volume control functions, but goes from muted to full volume in just 4 steps; raising it higher has no effect. It gets stranger: in Alsamixer or gnome-alsa-mixer I can see that lowering the desktop volume control to mute causes Master, PCM, Front, Surround, Center, LFE, and Side all to go to zero. Raising the desktop control one step causes all of these but Front to go to 100% instantly. Increasing the desktop control by a few more steps causes Front to step to 100%, after which no further volume increase is perceived. It's as if each step in the desktop volume equals some 25% of the Front setting, and 100% of the others. The audio setting in System, Preferences, Sound, Hardware is "Analog Stereo Output."
If I click 'Mute' on Master in the mixer then all the speakers mute, but unmuting Master does not unmute anything else. Only after I move and release the mouse-down state from the master volume do the other channels unmute. The volume control in Rythmbox, on the other hand, works seemingly correctly (maybe its going thru Pulseaudio?) And as an aside, why are there no controls for Pulse if it sits on top of ALSA?
I'm really confused by this, as all of it work as "expected" while running 9.10. Here is some output from this system (an ASUS M4A78T-E):
I've installed a clean Ubuntu 10.04 Lucid Lynx on my ThinkPad T61, and everything seems to be OK, but I am unable to get any sound output at all (internal speakers and external audio).
No system sounds, no sound from Movie Player, Rythmbox, Sound Recorder.
On my previous Ubuntu 9.04 and 9.10 I had no problems with sound (as far as I can recall).
Any hints to what I should do to try to get sound output?
The output from various sound related commands included below.
I have bought a laptop 2 months ago with pre installed windows7 and installed Ubuntu 10.04 64bit but still didnt get sound from the speakers. With headphones everything is OK . I have unmuted everything and searched forums but nothing so far. In windows I get speaker sound so it is not hardware problem. In alsamixer it appears I have 2 soundcards, one HDA -intel (chip Realtek ALC272) and a second one HDA nvidia ( a virtual one propably from my nvidia VGA ) that lacks controls . With lspci -v , it appears both use the same driver :Kernel driver in use: HDA IKernel modules: snd-hda-intel . Tried to disable the first one from bios but it didnt help I also tried sound adjustment in preferences -> sound and gnome-alsamixer, nothing From gnome alsamixer, when I mute speakers, the headphones also get mute so may be the system doesnt recognize speakers and headphones separately ? May be it has to do with config files but my linux knowledge is low
The only user that can make the sound card work on a F10 x86_64 system is root. For non root users, I am not seeing any error messages when a app tries to use/access the sound card, just nothing plays. As I said, for root everything works as expected. I am sure this is a permission/setup issue, but I have no idea where to start.
For the last 3 release all my hardware have been working like a charm. But after upgrading to Lycid I have problems with skype. I fix the camera issues with the following command
LD_PRELOAD=/usr/lib/libv4l/v4l1compat.so skype
But the sound of my microphone is totally jagged. I have an ICH8 Intel integrated card. I have worked the last 2 years (with an ocasionally glith in the volume) but not having Mic is a real PITAo what can I try to fix it? Please, don't tell me "remove all pulse audio stuff"... It must be another way.
I've spent the past 2 days attempting to get the sound working on a Toshiba A75 notebook. Here is what i've tried so far: remove/purge alsa and pulse audio then reinstall set up/configure OSS download and compile latest alsa drivers. code...
My questions are: is there anyone using this laptop on Lucid with sound? Can anyone provide a new idea how to make this work if it is compatible hardware.
I have had sound issues with Ubuntu since I switched from Windows. I must say I am enjoying using Linux but, am consistently frustrated with my sound issues. Infortunately, I still can't "fix" my sound to use it to its full potential. The steps I took to get to my current setup are shown in this past thread. [URL] I will sum up behavior and specs:
1. I have a 4.1 speaker sound system that includes, headphone port, mic input, and some usb game ports.
2. I have pulse audio all updated but I have it set to audio duplex otherwise the connection terminates. Meaning, I can't set it to 4.1 output. If I do set it to 4.1 the sound is uneven (amplitude) out of sync and poppy.
3. When I have it set to duplex, I hear decent sound except when I play audio or video files on vlc or rythmbox. Internet vidoe sounds and startup sounds are fine.
4. The sound card for the system is recognized as CS46xx. I have a Hercules Game Theater XP sound card. This is consistent with the alsa.org listing.
I just updated the kernel to fix nvidia video problem. But now I have problem of no sound. I think it may be unrelated to the upgrade of kernel because most or all of the symptoms were already present, or the upgrade may have complicated things even more. Another recent symptom in conjunction with this problem is that "restart" and "shutdown" from panel dropdown do not work -- they just log out. May or may not be related at all.
Here is link to output of alsa-info.sh: [URL]. I saw this thread about upgrading alsa, but it seems to indicate that later than 2.6.32 kernel not supported (????): [URL] Here is my /etc/modprobe.d/alsa-base.conf. The last line, "options snd-hda-intel model=basic" was from suggestions I found in other threads.
I have sound if I use aplay or start totem using sudo but neither have sound if I try aplay or totem as ordinary user. The groups command shows my user name is a member of the audio and video groups. If I look at the /etc/group file it also shows pulse as a member of audio group.
This is a command line install from the 10.04 Alternate CD to which I installed xorg, icewm, gdm, nautilus, synaptic, totem, firefox, gstreamer, alsa, pulse, and others. Every thing works except the user audio. Totem will show videos but no sound. Totem will play MP3 music files (show the cover art and the progress) but no sound. But it all works ok, good sound, if I start Totem as root.
What am I missing? I don't expect in depth help with this installation but thought maybe something would just pop out at someone?
Quite some time ago I managed to get sound working perfectly on my DELL Inspiron 1720 under openSUSE 11.2 and KDE 4.3.5. Then suddenly some months ago for one of the four regular users on my system sound stopped working! KMix is always muted after KDE session startup for this user and even if you unmute it there's still absolutely no sound; in particular, the commandspeaker-test -c2 -l5 -twavdoesn't generate any sound (while I do see the printed output which doesn't contain any error messages). Even if I su to root in the very same Konsole window speaker-test remains silent!
Since sound is OK for the three other regular users I've already compared KMix settings as well as System Settings > Multimedia for each of the regular users but found absolutely no differences. BTW: In System Settings > Multimedia I have XINE set as the backend and "PulseAudio" has priority over "HDA Intel (STAC92xx Analog)" for all sort of audio output, and - perhaps needless to mention - all the four regular users are members of group "audio".
I'm not able to hear any sounds from my system. The panel does not have the volume control button anymore. I'm not able to run System -> Preferences -> Sound. I get an error saying "Waiting for sound system to respond" And if I run 'pavucontrol' in the terminal, I get "Connection failed: Connection refused"
Also recently I've noticed that when I run some commands in the terminal I often get this message "Home directory /root not ours." Can this be related to the sound problem? I am on the system as root.
My problem started when I updated Ubuntu 10.10 developer release (or whatever it's called ) to Ubuntu 10.10 Final. When I switch user or lock the screen and log back in, my computer makes no sound. I know it's not muted since I can see that in the volume control. The only way I can fix it is by restarting my computer
