Ubuntu :: Recording Several Desktops And Each Sounds At Same Time / Stop It?
Sep 28, 2010
I'm trying to develop a system that records different desktops at the same time. I have developed a audio-videochat system and I want to be able to record what happens in every room, so my starting idea was:
1) Open a graphic terminal for each room. I have succeeded using vncserver :NumberDisplay.
2) In each terminal, run firefox at each URL. I succeeded too because firefox lets me specify in wich NumberDisplay I want it to be open
3) In each terminal, run recordmydesktop to record. It allows too to specify the NumberDisplay.
My problem now is that it seems that the sound card is "shared", so the sounds recorded in the display 1 includes the sound generated in all others firefox windows. I havnt found an analogy for the sound as the display is for the graphics.
I have thought some ideas but I havnt been able to materialize anyone.
Im tried to create virtual sound cards and specify one for each vncserver, I tried to redirect the sound of each firefox window to one "channel" (read firefox delegates the sound so that might not be an option), I read many things about pulseaudio, jack and several stuff that I just havnt been able to work.

I want to start recording when someone starts talking, and stop recording when it becomes silent. I guess if there is stream audio processing tool like ImageMagick, so I can strip away blank sections like this:
$ rec -t wav - | wavefilter -strip-blank=3sec | lame - >record1.mp3
EDIT This question is resolved by using:
$ rec -t wav - silence 1 0.1 3% -1 1.0 3% | lame - >record1.mp3

I'm trying out Konqueror on Debian Lenny. I'm annoyed by the sounds it plays along with message boxes (for instance: sound of a breaking glass on message boxes showing an error). I can't neither find any setting for that nor I've been able to find some general setting.

I want to record conversations and stuff from skype. Now, I want the sound to be as good as possible, so what settings do I choose, what do I mute and all the other volume combinations and settings do I configure etc... To get the best record possible, I need to record from both pc and mic at the same time, but how? As my settings are now I can only record through the mic. So, what do I do? Also, if you could give me a few tips on how I can filter useless background noise.

Does anyone know of a good time keeping/recording program for Ubuntu that I can use to log hours spent on a project for billing purposes? I'm getting back to doing some web work to make some extra cash, and would love to have a program that does this.

I have a problem regarding speech recording and i couldn't find a way around it. I want to record voice while at the same time processing it. Let me explain some more, what i want to do is to keep on speaking and it should be recorded in a file which i can process at the same time. If somebody knows of any such program or way to do this(like some code in C which can auto direct the recorder to keep on recording and saving).

I've worked out how to get ALSA libasound code working for an application. However I can't workout how to get multiple sounds working at once. I can't seem to find any google examples of mutiple sounds. EG tune plays while pressing buttons makes clicks. I'm using an embedded board so need to use ALSA not an addon e.g. sdlmixer, jack, etc.

I have a HP laptop model HP G72 Notebook PC, Processor Intel(R) Core(TM) i3 CPU M 350 @2.27GHz & the Sound devices are Intel(R) Display Audio & Realtek High Definition Audio.
This machine came loaded with Windows7 & I have successfully dual booted it with Ubuntu Lucid 10.04.3.
The problem I am having is that I cannot get the sound to work at all in Ubuntu. No opening sounds or anything else that I have tried. No Web sounds, no CD sounds... All sounds work fine on the Windows side, but nothing I have tried so far seem to work with Ubuntu & I have tried many options from many threads.

I've been using opensuse for about a week.(although I'm not completely a linux noob) I've been slowly moving more of the stuff I do on windows over to suse. I thought my sound was working fine until I decided to get mp3s running on amarok. I followed a bunch of guides which didn't work. While I was messing around with stuff I noticed a startup noise. I just assumed it didn't have a startup noise. At some point I broke all of my sound except running wine, so I reinstalled.
Now that I've noticed, none of my notification sounds work. Stuff like skype, firefox, and wine still give me sounds.
(If anyone could point me in the direction of a good place to get mp3s working on amarok would be nice as well.)

I think I selected the wrong time during the installation and now at the top right corner, my time keeps changing back to one hour ahead. Not sure why.I've went into the Preferences of the Time/Date > Time Settings > and set an hour back manually. I check back in 30-45 minutes, it's back another hour ahead. I'm on a Dell Inspiron 1545.

I recently bought a Shuttle XS-35 Mini-Barebone-PC and filled it with a 2GB Corsair RAM and a 1 TB WD Scorpion Blue Drive.After assembling all the parts I simply wanted to install Ubuntu but it simply doesn't work. However then I had the idea it would be good to kinda get the drive to a completely clean state and used the tools to safely wipe the whole HDD (by writing zeros everywhere as the tool tells me). The tool ran good for around 30 minutes but suddenly the write speed showing in the console window would go down to 0B/s (meaning basically nothing at all I suppose). I tried it 2 more times and it always came to a halt at the 10-20GB mark.
So this lead me to belief that that is also the problem while installing, that my drive doesn't want to wark anymore but rather just sleep a bit.What could be the problem? Is it a hardware error? Is there some linux system setting that could whip my HDD whenever it gets lazy? Did I do something else wrong?

Every time I boot up I have to go through a disk check and then restart, how do I stop it from happening? When the disk checks happening I press escape and it usually says its deleted inode something because it has zero Dtime or some thing similar and also a paragraph of repeated lines saying something like all system files need alsa base.cnfg it will be ignored in a future release then the disk check completes and it restarts and is fine then, also sometimes it says dev/sda5 (my ubuntu partition) was not cleanly unmounted check forces. Is their a way to stop this happening as it ends up taking ages just to login.

What is the correct way to stop upstart services from staring at boot time ? I'm doing something like this example in /etc/init/mysql.conf:
Code:
#start on (net-device-up
# and local-filesystems
# and runlevel [2345])
start on runlevel [!0123456] # I ADDED THIS LINE (and commented the above ones)
stop on runlevel [016]
1. Is this the correct way ?
2. Is there no way of doing something like we do with update-rc.d -f apache2 remove ?
3. When will ubuntu ship a gui to add or remove services from boot ?

lenny gives me either system sounds, or other sounds like flash plugin sounds like videos, cd playback etc., but not both. to hear videos i have to disable system sounds. as soon as i tick enable software sound mixing (esd) in system -> preferences -> sound -> sounds, videos goes. a message saying it could not open the resource as something else is using it comes up when trying to play a cd. sounds like a threading problem in some program. what should i do to get sounds to be equitably shared by all?

I have Ubuntu 10.04.1 32bit installed on my flash drive so wherever I go I can have my own mini personal computer, but one problem I'm having is every computer it is run on the next time it's rebooted to the OS on the hard drive it has UTC time instead of the actual time for the timezone you're in that Windows uses. So is their a way I can make Ubuntu not automatically change the clock to what it wants?

Just installed F15 using preupgrade (from F14) and now, every time I reboot, time jumps backwards 4 hours. If I reboot twice in a row without correcting the time, time will be off by 8 hours. Time zone is set correctly (Eastern Time). "Synchronize date and time over the network" is unchecked.
Since the difference between GMT and Eastern time is 4 hours, there appears to be some confusion over that but I can't find anything in the "Date & Time" app relative to that to try to play with to see if I can correct this. II do remember a similar issue many releases ago but I can't remember how it was dealt with.
Any ideas on how to diagnose and fix this?

i'm running 11.2 kde 4.3. i'm having issues with both smplayer and vlc. first, when i play an audio cd through smplayer, it pauses every 14-15 second. by pause i mean that the sound and time counter stops, and i actually hear the disc drive make a sound, the *typical disc-read sound. i tried a few discs, in case it was a specific cd; same thing for all. i also looked through the preferences to see if there was a setting that addressed it; nothing i see seems to address the issue.
playing the same cds in kscd works fine. but kscd really sucks....excuse me, it really really sucks. with vlc, whenever i start vlc, it will appear in my taskbar, but there is no other sign of its existence besides this. no system tray icon, no gui or any other sign of its presence besides the taskbar.

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.
