Ubuntu Multimedia :: Sound Is Not In Full Potential In Lucid Since Switched From Windows
Jul 11, 2010
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'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 recently purchased an external USB audio card [URL] All worked fine except the volume that comes out is BLASTING, and changing the master volume does nothing. Individual applications let me change their volume, but this is extremely anoying and often leads to me accidently blasting the room.

This is just a data point because these observations are semi-irreproducible results:
* sound. Sometimes the sound cuts out and no sound producing applications are able to use sound. I do not see any evidence for what happened in /var/log/messages. If there is something else I should look at, it would be nice to know. Nothing in the alsa stuff jumps out as a way to trace the activity, so I don't know how to provide any diagnostic info. After several reboots, it eventually restores itself and works correctly.
* video. Sometimes when I boot up, the secondary monitor has residual trash on the boot up/login screen. Other times, it is switched off entirely and I only get one monitor functioning when the desk top is finally up. Rebooting a few times clears this up, too.
The clear-up reboot requires a full shut down, not just a KDE restart. That is always ineffective when these problems present themselves, so these are likely driver level issues. I do not know where developers get their suggestions, but here's one: for each subsystem, have some well-named "I need diagnostics for this" thing available under the yast administrator stuff. That would turn on diagnostics for the subsystem. Then, I could turn it on for X and get something a bit better than the .xsession-errors (which showed nothing obvious for this problem) and for sound (aka "alsa" for those in the know).

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

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 just installed Lucid X64 on my PhenomX4 machine and I can't get my 5.1 speakers working. Only works in stereo.
Sound Preferences have only stereo options, how can I get surround 5.1? If it helps, I have Realtek for sound.

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.
Code:
$ sudo lshw -C sound

product: 82801H (ICH8 Family) HD Audio Controller

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

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 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.
Code:
# autoloader aliases
install sound-slot-0 /sbin/modprobe snd-card-0
install sound-slot-1 /sbin/modprobe snd-card-1
install sound-slot-2 /sbin/modprobe snd-card-2
install sound-slot-3 /sbin/modprobe snd-card-3
install sound-slot-4 /sbin/modprobe snd-card-4
install sound-slot-5 /sbin/modprobe snd-card-5
install sound-slot-6 /sbin/modprobe snd-card-6
install sound-slot-7 /sbin/modprobe snd-card-7

I put ubuntu on an old 3 ghz p4 and I went on to ....., the video was choppy especially when I switched to fullscreen. I have heard that flash is slower in linux, but here's the thing I have an old live cd for a distro called artistx, I think I burned in 2008, and I remember watching flash videos fine on it. I put it in the pc just to test it and then after it booted I went to ..... and watched the same video in 480p and fullscreen and it played back smoothly. Has flash gotten slower or is it ubuntu?

i'm trying since ubuntu karmic to set up a xorg.conf for a special purpose. I've a htpc connected to my tv. Intel GMA 4500, DVI->HDMI-cable connected, Lucid Lynx installed. When the machine boots with the TV powered on, everything is perfect. xrandr reports all valid modes on output "DP2". Without the TV powerd on, Lucid starts in the low graphics mode, with the funny zenity-message. So far, i managed to disable all useless outputs (VGA1, HDMI1, DP1, HDMI2), leaving DP2 enabled. I managed this by assigning outputs to monitors and adding Option "Ignore" "True" to the corresponding monitor-sections. My only remaining problem is, that the intel-driver reports no connected monitor on output DP2. The TV is connected, but shut off. Has anyone got a hint to tell the driver to ignore the presence of a monitor?

My Compaq Presario F700 laptop has Conexant HD-Audio SmartAudio 221 (checking from my Windows partition). I had everything working just fine until yesterday when I attempted to manually install an alsa-linux package that I downloaded sometime ago. Although the .deb package failed to install, it seems it messed things up and now there's no sound. The speaker icon shows "All mute" and I have no clue how to fix this. How do I 'unmute' it?

Is there any way to make Ubuntu play sound like Windows 7? I mean when i, for example, listen to music in Windows 7 the sound is much clearer and besides that i can use room correction to obtain a better surround feeling, but when i listen to music in Ubuntu the sound is not very clear and it sounds like stereo even though the sound is played back through all the speakers (the bass is also a little bit to high).
So far i've tried installing the alsa driver and modifying the output levels of each channel, but didn't quite have the same result as the room correction feature in Windows, and the sound wasn't any clearer either. Note: I have an onboard Realtek soundcard and Logitech x530 speakers

I run "aptitude update;aptitude full-upgrade" today, then I updated /etc/default/grub changing only the default boot line number, and I dully run update-grub, with no error messages. Now Kubuntu will not boot. The new kernel 2.6.32-22 is in the boot menu. When I turn the computer on, a blinking cursor appears on top line, column 8, and after a few seconds this cursor disappears and the screen is blank - my monitor indicates no video signal.
The failsafe 2.6.32-22 grub line does not boot either. I tried pressing Ctrl-Alt-F1, Ctrl-Alt-F2 etc. up to Ctrl-Alt-F10 to get to a text mode login prompt, but the screen remains blank and my monitor indicates no video signal. The workaround is to boot to kernel 2.6.32-21. The machine is Athlon XP, 2GB RAM, ATI Radeon 9600

This is my third Ubuntu installation, and even with identical hardware, sound volume is dramatically less than under Windows. I turn every slider up all the way, and it is still less than half as loud as Windows.

I've just installed Ubuntu and it seems the sound isnt working in it. Anyway - i have two screens. One is a tv and i want the sound to come out of there(its running through a hdmi cable).Works completely fine in windows. I havn't installed nivada plugin thingy as it stops my dual monitors working =(. So maybe this is the problem? From what i remember it worked in wubi though (without nivada drivers)I followed the troubleshoot and couldn't seem to find anything wrong?

I have configured PulseAudio with an MPD system-wide as I want to run PulseAudio without an X-Window Server environment, as I'm going to let my netbook act as a "wireless speaker" for espeak to speak out; thus, minimizing the expense of getting a "whole-apartment audio equipment." This is something that I can figure this out, as I have configured PulseAudio to act as a sender by having a separate RTP stream when I configure it in a VNC client.
Plus, I want my Windows Vista 64-Bit machine to receive the output from PulseAudio. I did download the Windows version of PulseAudio from Cendio, but I have problems getting PulseAudio to work, even if I added load-module module-rtp-recv to default.pa in the PulseAudio directory that I installed in PulseAudio directory. I get error after error messages when I run pulseaudio.exe, so it looks to me that it's not going to work anyway.
So I deleted the entire PulseAudio directory. It said something about entropy that I did not know anything about it. So anyway, is there some sort of a server program that listens to PulseAudio output and then send that audio to the client? The server program in the Ubuntu Server (that I plan to use as a sender) must be able to run without an X-Window environment. Is this possible?
I tried to do a search when it comes to streaming audio from Linux to Windows, but the Google search result came up with "Streaming audio/sound from Windows to Linux" which did not turn out very well for me. As a result, I have no luck with doing a Google search for what I'm looking for. In short, is there some kind of daemon that listens for audio and distribute the sound to Windows? It will be for my internal network only.

how I fixed my sound problems, that happened only for "windows media 9" videos, after struggling for days changing the players etc. (using Ubuntu lucid 10.04 up to date)First search for "Ubuntu install w32codecs" (or w64codecs depending on your system bus width) and... install them as root or 'sudo'
Code:
$ sudo apt-get install w32codecs (or w64codecs)
After updating totem to the very latest version (May 12, 3 days ago) the problem happened to be likely from the source: gstreamer. So I tried to install the latest version of gstreamer, and it worked (the default one packaged in Ubuntu is dated 2008...).
Code:
try
{
install latest developer version
}
