General :: Ubuntu Audio Output Per Workspace / Application
Oct 20, 2010
I'm looking into building a media server that will output to 2 channels. I'd like to use Ubuntu however, if there's a better alternative, I'd be open to using it. I'd have 2 audio and video cards for output and what I'm interested in knowing is if there's a way to set the audio output to a specific card per application or workspace. Is there an easy way of doing this?
I want to output two applications one to a headphone and another to the regular speakers, what app can I use?? it would be better if I don't have to move from audio player, I tried with alsa sound mixer but for some readon it doesn't list the speakers
I currently have my desktop setup with two displays, one of them being my living room tv that I run Boxee on. My problem is that all the audio runs through the same speakers preventing me from listening to music or gaming at the same time as when Boxee is in use.
I would like to know if it's possible to split the audio so that an application of my choosing only outputs sound through my headphones. I was thinking it would be possible with some of the controls in pulse, but if it is I cannot figure it out.
How do tell an application to open in a specific workspace?
More info:
I like to have my C++ IDE in workspace 2, my Java IDE in workspace 3, and my email, browser and miscellaneous in workspace four. I also use a shell script that executes upon log in code...
Of course currently it all opens in the current workspace... Is there a way for me to specify which workspace each command should start in?
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?
I am using ubuntu 10.04 and opensuse 11.3. I would like to know how to assign each application to a specific worksapce. For example,when I open a pdf file, it will be moved to workspace2. When I open a movie, it will be moved to workspace3. In Leopard, "Space" have such features. I would like to know the way to achieve this in ubuntu and opensuse, in an easy way, meaning that just need to install a small package, not a big one , like compiz
Just installed a new computer with ubuntu 10.10. I assign shortkey alt+1 to move workspace left and alt+2 to move workspace right.When I move workspace the focus application move with me to the new workspace. That is kind of annoying since I usually build up my workspace with mail here, music here, surf here. After sometime with this new "feature/bug" I got application all over the place.1) How do I turn this off?2) How do I enable dragging application from one workspace to another.
1) I got a dual screen and I can drag applications on screen No2. But if I log out, reboot or close the application, it will go back to screen No1. Is it possible to memorize the position of an application on Screen No2?
2) I use workspace a lot. I like to split them by function. I got "Development": Netbeans, firefox (one on each screen), "communication": Evolution, gwibber, empathy (Evolution on 1 and the rest on 2) and "Entertainment" (anything not involving work)Every morning, I have to move my applications to the diferent workspace. It would be great if on startup they just go where I told them to be!
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 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
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 have two machines on a local area network (xp box and xubuntu box) and I want audio from both machines to be played from the same set of speakers. The problem is, the xubuntu machine doesn't have any sound output. There is no onboard sound card and all expansion slots are pci-x, so short of buying a pci-x sound card my only option for playing sound is to route audio through LAN to my xp computer.
I already have a program that will let me play music on one computer from another's speakers, but I am trying to set up a stream so that games and internet sound can be heard. Is it possible for me to do this?
Has anyone come across a means to output rss feeds to audio? A Google search led me on a "wild goose chase". I was looking for a newsbeuter or snownews plugin of sorts. Either realtime output to speakers or piped to speex/ogg/mp3 I *really* need to learn how to code, so I can do these things myself
The default output audio port Ubuntu doesn't work on my system. It should be "Analog Mono Output/Amplifier", instead of "Analog Output/Amplifier". I can easily change that in sound preferences, just by choosing the right port in the "Output" tab. The problem is this would only apply to a single account, and I would like to change it system-wide, so it applies to all accounts on the system (I have more than 100 users...).
Update: I can achieve the same effect as I would by changing it in sound preferences using the following command: pacmd 'set-sink-port' 'alsa_output.pci-0000_00_1f.5.analog-stereo analog-output-mono;output-amplifier-on' Unfortunately that's still not system-wide,
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):
I believe I may have found a bug in Unity. Under the right circumstances an application will jump from the workspace where I left them to my current workspace. This is most noticeable with VirtualBox. I built an Ubuntu 11.04 virtual machine so that I could test out new packages before I push them out to the rest of my machines. But the window for the virtual machine constantly appears in my current workspace. It may take a few minutes, or 30 minutes, but it will happen.
I can kind of understand it if a new window appears, but at least with VirtualBox, this happens on a running virtual machine seemingly randomly.
Is there any way to have workspaces on multiple rows without the workspace switcher added to a panel? I have limited screen space so i want to try and remove any unnecessary items. I have tried using a drawer, but the workspace application is not loaded until the drawer is opened once. Also note I am not running compiz as the computer is a netbook.
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'm using Busybox's Hush shell on an appliance running uClinux, and would like to make sure I'm not packing shared libraries that aren't actually used by any application. I couldn't figure out how to compile "ldd" for that environment, but I could compile "readelf" which does the job:
Quote: find /bin -type f -print0 | xargs -0 ./readelf -d File: /bin/myapp Dynamic section at offset 0x7f4c contains 20 entries: Tag Type Name/Value 0x00000001 (NEEDED) Shared library: [libgcc_s.so.1] 0x00000001 (NEEDED) Shared library: [libc.so.0]
I was wondering if it possible to format the output so that I would get something like this instead:Quote:
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 just installed Ubuntu 10.10 last evening and all has been going well. Lucid didn't work out for me, so I used other distros. 10.10 fixed all issues except one thing. This is a need for me; e-courses I take require that I use Elluminate Live, a Java-based conference software. It runs flawlessly on every distro except Ubuntu. I had to use another PC running a different distro in order to get to a class. I really don't want to do that all the time. I thought it may be OpenJDK, but I found that Sun Java was installed and in use (I installed the extras while installing). I tried OpenJDK (worth a shot eh?) and the exact issue persists. All other programs have perfect audio.
