Hardware :: Sound Device Disappeared?
Feb 21, 2010
I'm afraid I don't know much about h/w and I'm not sure how to proceed at the moment... My Linux system is running Fedora 12, and it has been working fine since I bought it several months ago. But when it got rebooted the other day after a kernel upgrade, the sound system appears to have disappeared. I can play movies but there is no audio channel, and games have no sound.Checked in /dev and things like sndstat, pcmixer, audio don't exist.I don't know what sound card was originally installed or if the sound is built into my motherboard - I can probably find out if necessary but I have not yet taken the machine apart to look.Question - is there any easy way to probe the system and figure out what hardware is installed? Can I reload the sound drivers? Not sure what the correct procedure is in the current situation.

I installed Kubuntu 10.10 Trinity, ran the updates, installed a number of programs, and somewhere along the line all the device icons disappeared from the desktop. I didn't notice exactly when it happened because I couldn't see the desktop most of the time. They're all still checked in Configure Desktop / Behavior / Device Icons; I can check or uncheck whatever I want there, but it has no effect. How I can get them back?

For those that use Virtualbox on their slackware host and have a windows (xp) guest running. I have tried various settings for sound (Alsa, PulseAudio), the AC97 drivers are installed in the Windows xp guest os, but there is no sound and there is an unknown audio device (in the windows device manager). If I remove the AC97 drivers and use the soundblaster16 drivers in the Vbox settings there is no unknown sound device, but there's still no sound. why I can't get sound working?

So I was watching a video, and I changed the volume, and then the sound cut out, and it has not come back. No sound can be heard, from flash nor from files; through my laptop speakers nor my external speakers

On a system with a PCChips P17G motherboard, the sound has "disappeared".I was running Slackware 12.2, and sound worked fine. I upgraded to Slackware 13.1, and found that the sound didn't work.Looking into it, the sound devices are not found at boot, viewing dmesgSo I checked BIOS, and found the onboard sound capability enabled.

My Sound and Network Applets have disappeared. Probably with help from a seven year old. When I right click the panel to "Add to Panel" neither Sound/Volume nor the Network Applet are available in the list. So how do I fix it?

I have a fresh install of Natty and i'm having some issues getting sound to work. My laptop has a built in sound card which works just fine. However, i also have a usb 5.1 sound card which isn't working at all. Both devices show up in 'Sound Preferences' but when i select the 5.1 device as the output device sound doesnt work. I ran the alsa-info.sh script and the output can be found here.

I had good working installation of Fedora 12 x86_64 on my desktop, but few days ago, during watch movie in mplayer, sound disappeared. Till today i can't figure out, what happened - no errors displayed, no changes in configuration and no sound (both KDE and Gnome).
I checked soundcard in ubuntu live cd and it works fine. Also on login screen in my current Fedora 12 "beep" plays when i choose user, but after this i have no sounds.
I have up to date system, pulseaudio installed (i tried to remove it, but with no effect - without it also no sound).
Strange thing is, that sound disappeared during normal work, not after update or install anything.

I have been so happy using Debian Lenny. But just lately my sound has disappeared. I have checked the system and apparently it is SoundMax Integrated Digital Sound that I have on board. I have tried lots of things to get it going but to no avail. I have the Debian CD's. Is there a chance that it might be on these and I could re-install it?

Recently I installed JACK and Ardour to try out. Later I decided against it and so I uninstalled them. After restarting my computer, I noticed that the sound applet has disappeared from the panel, although the battery and mail icons are still present. There is still sound coming out of my laptop speakers, but it is stuck at whatever volume I had it set on before the last time I shut down. Volume sliders inside Banshee and suchll function, but I cannot change the overall system volume, and my keyboard shortcuts for this have stopped working as well. When I go into System->Preferences->Sound, all I get is a message that says "Waiting for sound system to respond." and nothing happens. I've tried searching around for a solution, but nobody I could find seems to have had aimilar problem, and none of the various other solutions proposed have worked for me. I'm on Ubuntu 10.10 by the way.

I've followed the steps outlined in the Fedora FAQ regarding sound issues. I am attempting to play some MP3 files using RhythmBox, and there's no sound. I have dug a bit deeper. I've tried alsamixer, and when I press F6 (Select Sound Card), I see three entries:
- (default)
0 HDA Intel
1 HDA NVidia
I have tried selecting a different sound card. When I select 1, I see this text: "This sound device does not have any controls". I have an NVidia GeForce 480 video card, but it has been suggested to me that I don't want to use it for sound. My speakers are in my monitor. I would assume that has ramifications on how I set things up for sound within Fedora. I have used some kind of sound test utility by executing this at the command prompt:
"speaker-test -c 2 -t wav".
I hear nothing. I don't know what to do next. If anyone can IM with me using Pidgin, that would be perfect

I'm trying to figure out what in the world is going on with my sound in OpenSuSE. I put in a brand new Audigy chipset soundcard and finally got some sound to come out of the speakers. I used the guide here: SDB:AudioTroubleshooting - openSUSE. to fix the permissions on my sound and am able to get sound-test to play sounds as well as connect to the sound device in my vmware and play sounds. That being said, I have terrible sound quality coming out. There is a lot of static sound like white noise and the volume of the actual sound played is very low compared to the noise. The sounds also distort somewhat.
I have tried the pulse audio change in the tutorial above also and have been searching around google. The only problem that I saw similar was a person who fixed the problem by updating KDE. I don't have KDE, I'm using Afterstep.

I have the impression that the sound device is still occupied. Probably I do not properly kill the recording process and I guess that invoking the script 'record.sh' via fcrontab contributes to the problem as well.Is there someone who has an idea what could lead to that 'silence'?

I've just installed GTick, a metronome application, (didn't find its forum, probably not supported), and it does not work - gives the error: Couldn't start metronome.Please check if specified sound device and sample file are accessible.It simply looks for the files at: /dev/dsp.I'm using Ubuntu 9.* and no such directory exists.Where are this files located?

I am trying to record a video clip, using my webcam, but sound synchronisation is always poor. I have used Cheese, UCView and VLC. One possible cause is explained in the reply to this question, but I am not an expert. In desperation, I now want to try ffmpeg. The ffmpeg documentation gives the following example
Code:
ffmpeg -f oss -i /dev/dsp -f video4linux2 -i /dev/video0 /tmp/out.mpg
My system has no /dev/dsp, but does have /dev/snd with these files
Code:
$ ls /dev/snd
[Code]...

I installed "Theocracy" on my 9.10 Karmic system. The installer asks for a sound device, dev/dsp is the default and I didn't change it. When I now try to start the game, I get the following error:
Unable to open sound device: Device or resource busy
Aborted
Execution of /usr/games/theocracy_base/theocracy.real failed!
What is the sound device when using PulseAudio on Karmic?

I don't have any sound in my external device (TV). I'm attempting to watch a movie on the VLC player but I can't seem to get the sound to work through my television speakers! They are coming out of my computer speakers just fine though.

There was a thread about this but no solution came about. mp3blaster always gives me the error Failed to open sound device whenever I try to play a song, and I'm not sure how to fix that.

Code:
ffmpeg -f oss -i /dev/dsp -f video4linux2 -i /dev/video0 /tmp/out.mpg
I want to use alsa, not oss, but need to know the alsa input device name (/dev/dsp is created by loading the oss modules). By running alsamixer, I have nutted out that /dev/snd/controlC0 refers to the HDA Intel sound card, ~controlC1 is my USB webcam and ~controlC29 is the microphone built in to my notebook, but these are control devices, not inputs.
[Code]...
However, that does not explain which device is the mic built in to the laptop: by my calculation, it should be pcmC0D1c, but there is no such device. In /proc/asound/card0/pcm0c/ I have directories for sub0 and sub1, which I am guessing relate to the mic jack and inbuilt mic respectively. Do two physical mics share one logical device somehow? I am starting to really confuse myself, if you haven't guessed that already.
I think my question boils down to "How do I record a video clip on Fedora 14 using ffmpeg?", but I am specifically interested in knowing how to specify each of the alsa sound input devices for my system.

I have old app that by default is looking for /dev/dsp as an audio device. The source is configured as such and I want to change that so sound will work on current versions of Fedora.
What is the equivalent of /dev/dsp in F15 ?
I think /dev/dsp was the default generic sound device .. ?

I have two sound cards active on this machine and they both work fine. However I would like to blacklist one card from being used for audio capture in KDE, because I am already using it outside of KDE for timed recording. The problem is that when I start amarok while timed recording is going on, it attempts to probe the card and this causes the recording to abort.
In Configure desktop > Multimedia, I can see the two cards. I can alter the priority but the Remove button is greyed out. So I can't remove a card from phonon.
Searching around for where phonon stores its configuration led me to ~/.config/kde.org/libphonon.conf. This certainly looks like the info I was trying to edit, but it's encoded in some way code...

i know skype on Linux is crap but i have no choice as i now have only Ubuntu installed on this pc & I NEED SKYPE.so with the new version how do i select a particular sound device.i ask because skype only lets me select a specific sound 'platform' (pulseaudio).i have a motherboard with on-board sound & a USB voip phone (us robotics) and it the usb voip phone i want to use solely for skype
so is there something i can tell pulse audio that i want skype to ONLY use the usb phone or do i have to use the stupid sound preferences to change the system wide device to the usb phone which makes the whole thing a hindrance because i have no idea when someone calls me & when i have to quickly change the settings then turn off music then try to answer the call the person calling has gone!!!i like to have music playing in the background out of my hifi & the error noises come out of the usb phone as well when this is selected & to be honest it makes having a pc setup with multiple devices pointless and a hindrance

Just when I thought my hardware configuring woes were put to an end, I don't have any sound. Here is my lspci list.
Code:
debian:~# lspci | grep Audio
00:1b.0 Audio device: Intel Corporation 82801I (ICH9 Family) HD Audio Controller (rev 03)
And the aplay -l
Code:
debian:~# aplay -l
* List of PLAYBACK Hardware Devices *
card 0: Intel [HDA Intel], device 0: HDA Generic [HDA Generic]
