Software :: Audio Output Device Changes To 'dummy Output'?
Mar 27, 2010
I finally got audio working on my ubuntu 9.10 desktop... now I am having sound issues watching movies from a network share.The sound device continually randomly changes to "dummy output device" and then there is no sound output. The sound icon dissapears on the toolbar. To get it back and audio to start working I have to $sudo alsa force-reloadIt seems to happen everytime there is a network delay, the movie will stop for a second and then when it plays the sound is gone
Running 10.10 and win 7 on my HP dv6-2150us laptop and I'm having a few issues.
First how do I get HDMI audio output to my TV? I think I have just a integrated Intel graphics card. It works fine in windows but I can't seem to get it to work in Ubuntu. I tried searching but couldn't find anything pertaining to this issue.
I don't know anything about ubuntu. Could you guys help me out. I'm pretty knowledgeable with windows if you guys need a printout of something let me know. My friends getting really frustrated about this. Help!!i
So here's the situation. He plugs his audio jack into his computer and then into the speakers but it still plays from the computer speakers.
I use ubuntu lucid x86_64 with pulseaudio. There seems to be some issues with how the audio is sent to the sockets. When playing an MKV with surround sound "front" recieves none of the actors voices. it almost sounds like it is the rear sound. Centre/subwoofer sound works correctly. I also get a problem with headphones and front where I cannot mute front and allow only headphones instead I can just mute headphone socket. This is entirely confusing so I hope someone can help me in the right direction.
Hardware: Nvidia 7600 gfx P5QL-EM mobo with 8 channel surround sound audio and hdaudio/ac97 cable which is set to hdaudio on mine in both bios and physically connected cable.
Ubuntu 10.04 XFCE desktop.The Audio Output Device is "/dev/dsp1".When I specify this in VLC, the audio works perfectly.But when I am looking at a web page with flash, I can only see the video.There is no audio.How do you make Flash use the "/dev/dsp1" Audio Output Device?How do you make "/dev/dsp1" the default Audio Output Device for this system?
I have no more sound on my debian. The only audio output I can find is the "dummy output".
When I try ask to aplay -l to display my sound cards, here's the output :
Code: Select alldevice_list:268: aucune carte son n'a été trouvée... <=> french for "no sound card found"
But I can still see my card(s) using lspci :
Code: Select all00:03.0 Audio device: Intel Corporation Xeon E3-1200 v3/4th Gen Core Processor HD Audio Controller (rev 06) Subsystem: Toshiba America Info Systems Device fa49 Flags: fast devsel, IRQ 255 Memory at f7a14000 (64-bit, non-prefetchable) [disabled] [size=16K] Capabilities: [50] Power Management version 2
[Code] ....
I already updated the system, reinstalled pulseaudio and alsa without any success.
I am running openSUSE 11.2 with an hda-intel sound card (dell latitude d830) in x64. Pulseaudio is only giving me a "dummy" sound card, even though volume in the yast sound configuration works. Volume is definitely not muted.Here is the requested info:alsa-info.sh:[URL]
Sound used to work fine on my computer, but one day my headphone jack stopped working -- when I tried to use it, no sound played through the headphones but did play through the computer's speakers.After I tried to fix it, I lost ALL sound on my computer. I noticed in my sound preferences it says "Dummy Output" and no other hardware.The problem seems common -- I've Googled the issue to death and read many threads here about the same problem -- but no matter how many times I've tried, I can't find a solution that works for me.I'm relatively new to Ubuntu and so there's still a great deal of stuff that
I finally decided to transition to a 64-bit install (AMD64). (same machine, just reinstalling as a 64-bit kernel starting w/ a Debian squeeze netinstall image) My audio chipset is nvidia MCP61, and it was working perfectly under a 32-bit kernel (I did the transition because a poorly-written system backup script (my fault) hosed /usr, /bin, and /sbin) When everything was up and running:
*: KDE4 only recognized the output device as ALC1200 Analog *: kmix only had a single channel(master) *: alsamixergui did recognize all the channels *: some games (sauerbraten, for example) had no sound in KDE4. *: some games (warzone2100, for example) did have sound in KDE4. *: the games that had no sound in KDE4 did have sound in fluxbox.
I removed the following packages (some of which I had installed to try to get audio working properly):
Say I have 2 speakers connected to 2 different sound cards. Under Windows, is it possible to have some sort of virtual device that would forward an audio stream to both sound cards? If this can't be easily done under Windows, a solution for Linux is also fine. lternatively, if the 2 speakers are connected to different channels of a sound card, is there any vendor-independent way to duplicate audio to both channels?
This started today in my session: no audio output. In sound preferences, hardware, in Profile, the options are now Off and Analog mono input. In Output tab, I see Dummy output stereo as the device. Nothing is muted.
I have a problem with the audio output in Fedora 15. It seems 'dirty' to me, like with a lot of distortion. I use for the output a nice USB DAC that seems to run very good with Ubuntu and Windows, strangely with Fedora isn't the same. I say strangely because the sound pipeline must be very similar to that of Ubuntu, no? Kernel, ALSA, Pulseaudio and so on. How could I improve mine audio output? Tried with Flash videos and Audacious audio player. Lowering audio output (like to 50%) greatly improve audio quality! Why is permitted to the system to go over and distort?
So I have a DAC/Headphone Amplifier which plugs in through USB. Through the system settings I'm able to set it as the preferred audio output option. This makes all the windows manager sounds come through the headphones, but all the applications still come through the laptop speakers; i guess they are completely independent of the system settings. I have to set each application's output preferences separately, and some software (like Firefox) doesn't have any output preferences. So is there a way toirect the audio output of all applications to all come through the USB DAC
I am sure that this is very simple but I have installed sound juicer and the gstreamer plug ins. The problem is i still cannot select MP3 as an output output option
I am using a sound card with the C-media CMI8788 chip. This card has both analog and digital outputs, which Linux sees as two different output devices.
The Problem I am having with VLC is that it always changes the output device in its settings to analog. I constantly have to be going into VLC advanced settings and picking Alsa: Digital for the output.
After that the sound outputs fine.
This only happens with VLC. All other programs on my pc output sound perfectly fine. I am using Lucid.
How can I set the default to be the digital output?
I have a StarTech USB audio adapter which I have been unable to get output from in Suse. Pavucontrol allows me to adjust the output to this device, and even shows some signal when playing media. However, no output makes it to the headset/speaker jack of the USB device. There does not appear to be any issues with playing media to the internal sound card & speakers of the computer. I booted up a Live Ubuntu disk, the device was recognized, and output made it with no problem. This leads me to discount a hardware problem. I'm running Suse 11.4 on a Lenovo Thinkpad T420s.
I just got rid of pulseaudio because it breaks in so many different situations. I've switched to Alsa, and all of my sound is working except in mpd. It seems like I have to set audio_output in /etc/mpd.conf. Here is my config file:
audio_output { type "alsa" driver "pcm" name "whatever" }
When I start mpd, this is what happens: $ sudo mpd --no-daemon --stdout --verbose playlist: play 1:"Party Playlist/01 Block Rockin' Beats.mp3" decoder: audio_format=44100:24:2, seekable=true alsa: default period_time = buffer_time/4 = 371519/4 = 92879 alsa: buffer_size=16384 period_size=4096 output: opened plugin=alsa name="My MPD Alsa Output" audio_format=44100:24:2 playlist: queue song 2:"Party Playlist/01 Umbrella [Feat. Jay-Z].mp3" output: closed plugin=alsa name="My MPD Alsa Output" ^Clisten: listen_global_finish called db_finish took 0.000000 seconds
And I hear the song play for less than a second before the audio_output driver is closed. There really aren't any error messages printed explaining why it's not working. I've also tried "oss", "esd" and "ao" for the audio_output type, and none of them work.
I'm looking for a program that will visualize anything that goes through my audio-output (in this case it's Spotify) and display it on the screen. Does this exist?
I installed Kubuntu 9.10 one week earlier and installed VLC player in it. But from that day VLC player is playing the video but not the audio. Also Banshee player is not playing any audio in Kubuntu.
Have you ever wanted to record a sound heard from your computer or website? If yes outRec is perfect for you. This simple but powerful application let you to record your sound card audio output easily in a few steps and save it in different kinds of formats like wav, mp3 or ogg.

To get it work you need to install the dependencies with:
My audio setup is based on a single guitar amplifier, and from this I suffer from only being able to listen to one of the two stereo channels. Since I honestly don't care for stereo, I'd rather force Ubuntu to output all audio as mono instead of "upgrading" to a stereo compatible setup.Is there a way to do this?
I have this file:Code:vid-gd-19940626-peggy.rmI would like to extract the audio and copy to a file to burn on a CD.'pitivi' will load the file and show the audio timeline. But I can not find a save or copy button.'vlc' will play the file but I can not find how to seperate/save the audio.I found a 'ffmpeg' that is suppose to read whatever is being sent to your speakers.Code:ffmpeg -f oss -i /dev/dsp -f video4linux2 out.wavThis produce a file that 'mplayer', 'vlc', 'audacity' will load but it is empty of useful data. Black screen only.This is the second week I have worked on this. Either I'm googling for the wrong words or what I'm reading, I don't understand.
I have just gotten unbuntu install and was force to learn cuase while installing i accidently messed up the part of windows it needs to start i think on another hard drive.
i dont mind anymore. its a easy learn but now i down to the nitty gritty stuff.my audio outputs. i have a biostar board with reltek onboard audio.board model: TF8200 A2+ now i am just looking for a way to manage what one of the 6 ports do what.. like before in windows 7 with the realtek program. i could make every single on back their all fronts. or all line ins. or anything in between.
i dont really no what else to say. what ever other info you need just ask and ill reply fast.ps Ubuntu is awesome. its so slick with compiz and conky is nice to. only other problem i have now is music manager/player/mp3 sync. anyone know a good program off the top of your head?
I am honestly uncertain if I ever had audio. I thought I did, but that may have been a different machine or a different install. I don't frequentl use anything that requires audio. Nothing is obviously muted, amixer has everthing turned up at least half way.
