I have a huge set of events in Mathematica that I need to react to, and it's not practical always checking for it, especially since events are randomly distributed in time.So I wanted to add a simple sound to remind me to go check the event. I wanted to use Beep[] but I get no results, in fact, I didn't realize till now that mathematica is making no sounds whatsoever.I use Debian Squeeze Stable and have no trouble with any other application using sound.
Many commands in Mathematica 8 (Integrate, Simplify, etc.) seem to only be using a single core on my system. Is there any way I can change the affinity so that it utilizes all cores for computations?
I Install Mathematica 4.0 on Ubuntu 10.04 and fedora 13. When i create new notebook file and save it, Mathematica front end automatically disappear. It shows message "Mathematica has received the signal: SIGSEGV and has exited" on terminal. But this not happing on older Linux version such as suse enterprise desktop 10. if i first create aaa.nb file using vi editor i can open it with Mathematica front end and save it. but cannot do "save as option" and also cannot open edit-> preferences menu.
I'm an undergraduate Physics student, and I would like to install a software for helping me with relatively simple tasks, such as calculating integrals, plotting graphs and performing some general numerical calculations. Can someone indicate me a good software for these purposes, preferably an official Debian package?
I use Mathematica 7.0 through my school's SSH server. This involves:
-loading their font server via "xset fp+ tcp/c1.ucalgary.ca:7100"
-connecting to the SSH server via "ssh -X useruser@servername.ca"
-entering my password Then I choose to run Mathematica via ". use mathematica 7" then to load the GUI "mathematica".
Sometimes, and only sometimes, the screen goes to the error in the attached picture, stays there for about 5 seconds, brings me to the login screen. When I log in again, all of my applications that were running, open folders, and my terminal windows are closed.
sound card is working well inside SuSE and everything is ok there. But when I install Windows 7 or XP inside Xen Virtualization software, I can't use sound card and Windows is unable to find any sound hardware.
trying to get everything set up in Debian lenny on my new Toshiba staellite L500. I have successfully installed the wireless drivers and graphics card and have them both up and running. But I'm having trouble with the sound card. Specifically, it appears to be installed but I cant get any sound or any devices related to sound (speakers, volume control, alsamixer) to work at all.
This problem presented itself upon upgrading to ubuntu 9.10. Any time something affects the sound system the buzz goes away. If a song plays, no buzz. If I simply adjust or mute the volume, no buzz. But after 10 seconds of no sound related activity, the buzz returns. This is a very loud and aggravating buzz, most likely made worse by the fact that I run my sound through an amplifier.
I'm trying to use an application (e.g., mplayer) to play sound that comes in my sound card (via the mic jack). (What I'm really trying to do is sync a sports broadcast by putting a delay on AM audio, as described here. I'm stuck at the part where it says "this shouldn't be too difficult".) I've seen some hints that there might be code-heavy solutions using LADSPA or some JACK SDK, but there's just gotta be a simpler way. I'm hoping for something like
Code:
mplayer -delay -7 - < /dev/mic
but I'm darned if I can find it. I'm sure there are plenty of other sports fans who would find this useful for syncing radio with the digital TV feed...
My usb sound card has been identified by alsamixer, however it won't make any sound when i put headphones in it. The volume is up, I know the sound card works.
I was just using the mic and watched it stop working suddenly. I was in the middle of a skype test call when the graphical mixer level died down to zero in the middle of the call. When the test call was played back, the first part sounded fine then the sound got lower until it became inaudible. Since then I can't get any sound from my mic in skype.
Also, the audio input level graphically shown in Sound Preferences shows no fluctuations in sound as it used to before. The input device is enabled. I tried using Sound Recorder to record some sound clips and that worked fine. So the mic is working but Sound Preferences and Skype seem to have the mic level really low. I'm not sure what else to think considering it was working perfectly a few minutes ago. I've tried restarting, but that didn't fix it either.
After installing an external sound card, Im having some weird issues. The cards chipset is fully supported by suse, (CM8738) so I dont think thats the problem. Besides, I'm getting sound, but not in some applications. The system's sounds work just fine (login, logout themes) amarok plays without any problems, kaffeine, mplayer they all work flawlessly, in fact I can see the difference in quality between the onboard sound and my new card. However, no web browser is able to play any sound at all, firefox, opera or chrome, nothing,zip. Plus, vlc cant reproduce sound either, nor can smplayer.
I've tried switching channels on and off(muting)in kmixer and in alsamixer, on the console, with no results. I disabled the onboard audio on the bios before installing the new card, however my ati video card has integrated sound, which I cant disable.... I used to get this exact same problem randomly with the onboard sound, but I just had to go to kmixer and turn up the "pcm" channel volume, which was set to 0, and I had sound again on my browser. However this card's pcm channel is at max and turning it up or down affects the whole systems volume, not just the browser's. Is it better to just reinstall the sound system, if so how could I do that.
I bought a Diamond Xtreme Sound 5.1 sound card because I had read online that this card was a good choice with Linux and came with universal driver software. I installed the hardware correctly (as it works with WinXP) but I'm not able to get it working with Ubuntu.
Since I upgraded to Ubuntu 10.40, I no longer have sound, except for the Ubuntu sound when it loads during start up. Does anyone know how I can recover sound on my computer?
I've got an urgent problem! I had some viruses as my program told me and in the end I had to restart my eee pc!Problem is now after it starts and you click on the log me in icon for the netbook it makes the nice hello sound, takes some time and then does the shut down (goodbye) sound. So basically the netbook booted already right? But I cant log myself in! What can I do?
I have been using Ubuntu as my main OS on my desktops for a couple of years now. Started off with a HP with a Creative Labs XiFi soundcard, but am now using a Dell with a Creative Labs Audigy. Sound worked perfectly on the Dell since a clean install (about 7 months ago). I turned it on a week or so ago, and no sound! Even the little sound indicator in the notification area has gone.
After installing I was not able to get many of the audio programmes to work. After some reading, I realised that this was probably due to jack not starting.
I was unable to get jack to start normally but have been able to get it started with the playback only option selected. Programmes that use jack now work, however there is no sound once jack has been started. The sound does work in other programs when jack is not started. Strangely, I only have to open qjackctl for the sound to stop, and jack is not even started. Initially I thought these problems were due to my sound card not being supported, but I believe that alsa support was added for the via 1708 codec at some point. I found that support had been added in a document showing the changes between alsa versions; however I cannot find the exact model listed as a supported sound card on the alsa site.
I believe that altering jack settings could fix the problem, as i have been able to get audio to work in hydrogen by selecting plughw:0 but there is still no sound in other programs. I have tried altering many other settings but to no avail, however I do not really understand the meaning of the settings that i am adjusting.
Does anyone know what settings to adjust or know something else that might fix this problem so that sound works once jack has been started?
Also, would programmes that use jack such as audacity, hydrogen, and ardour work with pulseaudio as the main sound server if I were to install normal ubuntu - it might be worth seeing if my soundcard works with the puleaudio sound server
if this helps, here is the error message received when jack does not start when the normal duplex option is selected.
21:24:04.867 Patchbay deactivated. 21:24:04.868 Statistics reset. 21:24:04.886 ALSA connection change. Cannot connect to server socket err = Connection refused
[Code].....
also, when i open alsamixer in the terminal for some reason the headphone part is greyed out, even when the sound is working before qjackctl is opened.
Running Compiz as a standalone WM.Managed to get Slim working, will post how later, but have no sound. If I boot using gdm3 the sound works. Obviously gdm3 loads something Slim doesn't, but can't workout what!Tried adding /usr/bin/pulseaudio --start --log-target=syslog & to my script - no dice, still no sound
I installed Mangler and one of its requirements was pulse-audio. I installed pulse-audio everything worked great except i couldn't get sound out of wow if i started mangler first and vice-versa. I then found a version of Mangler that worked with alsa. So i uninstalled mangler and pulse-audio, installed mangler-alsa. Everything works great now. The problem is when i uninstalled Pulse-audio i lost all my sliders in Yast > Hardware > Sound > other > volume. The only thing that shows up is master volume > Test. My sound works great just can't adjust anything. How do i get my sliders back. I would like some advice before i screw something up. (lol) My Sound card is according to sound configuration SBx00 Azalia(Intel HDA) - Driver snd-hda-intel.Opensuse 11.2 KDE 4.3.5
I have a newly set up computer with 11.4 64 bit. Intel Core i5, under Sound Configuration in YaST I have '5 Series/3400 Series Chipset High Definition Audio'and 'nVidia Corporation'I have built in speakers in my screen, connected via HDMI. I hear no sound from any source, neither via HDMI, nor via a separate sound cable connected to the sound connector on the back of the computer nor via the head phone jack on the front.
I have suse 11.4 installed and I wish to replace the on-board sound chip with an add-on sound card. The following are available at my local shop but they cannot advise whether any will work on Linux Suse 11.4.
Anyone know which of these cards will work on Suse 11.4?
Sound Blaster X-Fi Titanium HD Sound Blaster X-Fi Xtreme Audio Asus Xonar DS
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 have no sound, is it possible to restore the default sound drivers/settings in 10.04?It was work well before except for one issue, I couldn't get mic in for Rosetta Stone using wine. I have followed so many howto's to try and get Rosetta Stone working and then my sound working again.I think this is my main problem I upgraded alsa to "alsa-driver-1.0.23". I could easily be wrong about that assumption though.I have a Dell XPS M1210Ubuntu 10.04 64bitI think this is my sound card, "lspci -v | less"00:1b.0 Audio device: Intel Corporation N10/ICH 7 Family High Definition Audio Controller (rev 01)Subsystem: Dell Device 01d7Flags: bus master, fast devsel, latency 0, IRQ 11 Memory at efffc000 (64-bit, non-prefetchable) [size=16K]Capabilities: <access denied> Kernel modules: snd-hda-intelBut I don't think it is being recognized,
For a couple of days ago, maybe a week or two I beguinne to get a 'snap-sound' in my compurt sound, like an eletrick charge or someting. I comes with about a minutes period. I resently find out that it came from the center-speaker. I run Ubuntu 10.04 LTS and have this sound-card: 00:09.0 Audio device: nVidia Corporation MCP73 High Definition Audio (rev a1)
My speaker system is Logitech X-530 I have located the problem to center-speaker, but the snap-sound only disappear if I mute the center, not lower the input, in the GNOME ALSA Mixer. I have tried to disconnect the antenna to the analoge-TV-tuner. Has anyoe a similar problem, and a trick to fix it? I don't know if it's related to any recent update of the system?
Playing a song works at first; then it quits after 1-5 minutes. If you select a different output device, it will work for another 1-5 minutes, but switching back to an already used up device will not play sound. Running 'sudo killall pulseaudio' resets everything and each output device works for another 1-5 minutes. This is on on 9.10.
Recently I have started using my netbook (Acer Aspire one D250) alot more due to travelling and I noticed that the mic didn't work. Headed to the Ubuntu forums and saw a thread about installing ALSA. So I did and now I have no sound. From what I can tell ubuntu is no longer picking up my sound devices but I'm sure. Hence why I am here. I need to get my sound working again (obviously) and then in turn get my mic working for mumble and other VOIP programs.
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.
Strange one. Just upgraded my mother-in-law's computer from 8.04 to 10.04 via the update manager. All seems to be working beautifully except ...
* When I run gstreamer-properties and do an output test I get a test sound through the headphones plugged into the front audio socket of the machine using the 'Analogue Headphones' setting in Sound Preferences. (This rules out dead headphones.)
* When I try to play audio through any app I get no sound through the headphones, but if I change the setting to 'Analogue Output' in Sound Preferences I get audio loud and clear through the speakers which are plugged into the audio socket at the rear of the machine. how the gstreamer-properties test is getting audio to the front socket I guess I'd be getting somewhere.
