Ubuntu Multimedia :: Weirdest Sound - Static Buzz, But Only If Mainly Light Screen Colors?
Jan 28, 2011
There's this low monotone electronic buzz coming out of my speakers. But only if the greater part of my screen is using lighter colors! Meaning, if for instance I have the terminal (black) full-screen there is no buzz. If I have it sized over the half of my screen there's a medium buzz. And if I am on the Google Search home page with the browser full screen (most of the screen white) there's a loud buzz. :SAnd it's only if I run the sound through my amplifier. It's not audible if I just use the laptopspeakers. Really, I have no idea even in what direction to start looking.
I installed Ubuntu 10.10 last night, it worked fine, installed my graphics drivers, worked fine, and then I ran "sudo apt-get update" and then "sudo apt-get upgrade". There was about 240MB of packages to be downloaded, and since I was going to be on for a while, I did. I didn't restart after it finished, I just turned off my computer and went to bed.
Well now, when I turn on my computer and boot to Ubuntu, after the boot screen, my monitors stay on, but show a blank screen. There is no boot up sound, the HDD light is solid on, and I can't access terminal through Alt + Ctrl + F1.
I love my new HP Mini netbook, but every time I click 'shut down', there is this horrible buzzing sound that comes out of the speakers. I have the sound muted, but still the sound comes blaring out. This is very disruptive in class and I get a lot of nasty looks. If I have headphones plugged in, the sound blares through the headphones, even if sound is muted.
I'm thinking that this is a problem with PulseAudio.I searched and there are two previous posts: here and here. The second one says 'SOLVED', but obviously it is not.I'm running UNR Karmic.
My speakers are making continuous slight buzz sounds. I don't know why this is happening but when i am making my sound to mute all, the sound goes off. When I hear properly, it seems to be the sound of the hard-drive spinning sound, I couldn't under from where it is coming, its happening from past 4-5 days.
For some time now, my laptop makes a quick but loud buzz sound when I shutdown or restart it. Muting my sounds doesn't fix it. Before, it didn't do this. It just started one day and got worse till it happened everytime I shutdown or restart.
Going to preferences > sounds > changing sound theme to no sounds helped a bit and after doing this, it doesn't happen all the time anymore. This is quite disturbing especially when I'm in libraries. What worries me the most though is that it might affect my speaker.
I've just upgraded to Kubuntu 10.10 recently, and everything's working well, except that the screen seems to display less colors than it used to. It's very noticeable when looking at smooth gradients, since there are no smooth gradients anymore.
I'm using a laptop with a Radeon HD 5650 video card. The drivers seem to be working well, since I can run a 3D game like Nexuiz without any problems. The lack of colors isn't even very noticeable when playing games, but I can see it clearly in KDE... for example, the window background gradient isn't really a gradient now, just a few different shades of gray next to each other.I've looked around in KDE display settings and ATI settings, but there's absolutely nothing about the number of displayed colors there.
For the past month or so I have been having some issues with screen crashing and displaying funky colors. Basically it happens at completely random times, doing completely random things. The screen goes to a pink color then freezes the the only way I can gain control again is if I restart the machine or restart gdm via ssh. This is really puzzling me. Perhaps there are some logs I can look at? A little bit about my system:
Code:
Processor2x Intel(R) Core(TM)2 Duo CPU E8400 @ 3.00GHz Memory4059MB (1321MB used) Display[code].....
I have had linux 10.04 installed for a while now and have always had this problem. There is a constant static noise in the background in my headphones, it amplifies whenever I move the mouse or scroll etc.
I have tried searching for a way to fix this but nothing came up that was able to help me. I can't think of any other information I could give,
When i try to install Fedora 15 on a clean machine it freezes as soon as the pixelated load bar with the white, light blue and dark blue colors show.
I have tried several different versions of Fedora (64bit and 32bit) and have tried to burn it to a CD and/or DVD (For the larger version) and copying it to a usb pen with universal linux usb, liveUSB creator (from Fedora) and last one i don't remember the name on.
The sound stopped working on my Macbook Pro 1,1. It was working fine before, and I can't think of any changes I made that would make it stop working. I know it's not a hardware problem because the Apple sound plays when I turn on the computer. Everything is unmuted in ALSA Mixer. None of the hardware options in Sound Preferences produce sound. Plugging in headphones or speakers does not solve the problem. I'm using 10.10.One curiosity: Whenever I do something that would normally cause sound to play, the optical audio red light in the headphone jack turns on, but no sound plays.
Every time I login I get the abrt flashing light at the top of the screen, but nothing comes up. When I try to run it manually from Applications->System Tools->Automatic Bug Reporting Tool I get a popup with:

Error while loading the dumplist. org.freedesktop.DBus.Error.NoReply: Message did not receive a reply (timeout by message bus)Is anybody else seeing this? If so, any idea as to what's going on? How to fix it?
I could just dump abrt since it's hardly a necessity, but I'm inclined not to as I think it's a good idea which could potentially be of great benefit to us all.
Despite being warned from a friend of mine who works for Intel that the new version of Ubuntu 11.04 sucked? I upgraded from 10.10 which worked perfectly fine and did everything that I wanted it to except work with my COBY MP3 player which is what I hoped 11.04 would do. It all worked great until I rebooted. I previously had the main screen on the left where all of the menus are and the right screen was the 2nd monitor.
Once it rebooted it let me login and loaded the desktop but the main screen is now on the right with that stupid application bar going up the side, all of my folders, etc. are all there but NOTHING is clickable, even the icons up in the right corner where you logout, etc. will not do anything other than highlight that you have clicked on them, the hard drive light flickers for a few moments then nothing.
Also the left hand screen is completely blank unless I move the mouse cursor through it. If I just leave the computer sitting there eventually the screens go dark and the monitor lights start flashing like it is supposed to but if I wiggle the mouse the screens come back on and the mouse is there but there is no login prompt to let me log back in. Pardon my French but this OS is a piece of <bleep> and sucks just like I was told.
I'm using xterm/screen/vim, and set them up to 256 color mode. Everything went well, except when background color for the theme I choose is not black.
Here's the theme I use in this example:[URL].. Here's the situation: as long as I only use vim, the background is well rendered, meaning everything is grey in vim background. But when I try this with screen, the background is back to black, and only the text get some kind of highlight with the background color.Here are the magical lines I added to screenrc:
Code: term screen-256color attrcolor b ".I" # Tell screen how to set colors. AB = background, AF=foreground termcapinfo xterm 'Co#256:AB=E[48;5;%dm:AF=E[38;5;%dm' # Erase background with current bg color. Not needed if TERM=screen-256color defbce "on"
Colors are well rendered in 256 color, I only have a problem with this background. Anyone knows how to 'fix' this?
I installed the Cairo dock and wanted to get rid of the taskbar on the left side. Found out that getting rid of Mutter would do that. Not satisfied, so long story short, reinstalled Mutter. Now I only get a white screen. No wallpaper, colors, themes, nothing. As I shut Ubuntu off I will get a flash of my wallpaper and then it's gone. 2 questions really: How do I get things back the way they were? Can I keep the dock but lose the standard sidebar?
I have just upgrade from 10.04.to 11.04 When I restarted after upgrade installation I got message that I didn't have the hardware to run Unity, then I clicked on ok, now ununtu start, but it is very slow to start and the screen freeze and has different color, but after while it start. I am looking for advice to solve this problem.
I'm running a VNC server along with a local VNC viewer on the same RHEL5 box. The colors for my GUI components look O.K. in the VNC viewer, but a map that the viewer displays is messed up. The color of the map is too blue. My system is using X11 protocol. I'm a newbie when it comes to Linux.

how to get sound to my flat screen. Here is what i have graphics card (GeForce 8400 GS), ubuntu (9.10), tv (vizio va320e). currently hooked up dvi to hdmi
I'm running the latest version of Ubuntu and have been for a while now without issue. However today (actually now yesterday) i made the giant mistake of upgrading my on board HD3150 graphics to a PCIe HD5570 since then my whole life has fallen to bits.
First i noticed some visual noise on the screen. Concluding this was due to incorrect or out of date drivers i attempted to update them from the Hardware Drivers section. This gave the error:
SystemError: installArchives() failed
Activating from the command line using jockey gave the same error.
Deciding a reboot might be needed i did so. On power up all ubuntu and recovery modes produced an unskinned GUI with no desktop icons that responded to no mouse or keyboard input.
I was forced to reinstall the operating system.
On reinstalling and losing everything i had installed previously (it's going to take many days to get that all back and working again!), i still have the screen noise, have still been getting the same errors on attempting to activate the drivers, except now i also get this:
the installation of this driver failed.
Please have a look at the log file for details.: /var/log/jockey.log
Code: 2010-09-22 01:40:58,589 DEBUG: querying driver db <jockey.detection.LocalKernelModulesDriverDB instance at 0xa332aec> about HardwareID('modalias', 'usb:v045Ep00E1d0007dc00dsc00dp00ic03isc01ip02') 2010-09-22 01:40:58,589 DEBUG: querying driver db <jockey.detection.LocalKernelModulesDriverDB instance at 0xa332aec> about HardwareID('modalias', 'usb:v046Dp0804d0009dcEFdsc02dp01ic0Eisc01ip00')
I have installed XVidCap Screen Capture. If I record my screen with XVid Cap Screen Capture there is no sound. But if I record with Desktop Recorder there is sound. What is wrong?
I haven't installed or changed my system in anyway apart from the usual updates and all was fine until about a week ago. I can play videos back through any of the native linux players VLC, Movie player - But I only get black screen with sound - it was working fine and then suddenly - boink? The only program that can play back sound and video now is avidemux
I purged VLC - but I already knew it wouldn't fix it - since it was system wide So I installed VLC through winetricks to check and guess what - it works - all formats Anyone know what the problem could be? or more importantly how to fix it?
I am new to Linux (Ubuntu 10.4 LTS on a Thinkpad T40), now just two days, and had everything working nicely. But since I wanted a better higher resolution I tried to set the monitor resolution to a higher value. After selecting a higher resolution first the screen went black and now it has a white background and is steady but has flickering areas. The system is still working. How can I go back to the resolution that was working?
I have used Ubuntu and Linux Mint for quite some time now until I got a new machine. Some friends told me to try OpenSUSE because it has really been polished over the last few years.Install went smoothly got everything working properly except for my video card. My video card is an ATI HD4890 with sound support over HDMI. I had the sound working in Ubuntu using the non-oss ATI drivers. I was wondering if someone could please teach me how to install them again here on OpenSUSE 11.3. My screen fonts and colors also look terrible compared to Windows or Ubuntu.
Is there a way I can make it look better? I remember CCC (Catalyst Control Center for ATI) had two color formats (RGB and YCbCr). I had to set it to YCbCr because my screen is an HDTV and it looked much cleaner than RGB. Is there a way I can acheive similar results with OpenSUSE?
My problem started when I updated Ubuntu 10.10 developer release (or whatever it's called ) to Ubuntu 10.10 Final. When I switch user or lock the screen and log back in, my computer makes no sound. I know it's not muted since I can see that in the volume control. The only way I can fix it is by restarting my computer
i use forefox4 shiped with ubuntu 11.04, performed all updates but i noticed that pages colors are too bright or has more saturation than it is normally displayed.the attached file illustrate an image opened with image viewer on left and firefox on right.How can i fix the colors on firefox.
I noticed as I was watching a video that the colors are totally off. I don't have any problems with the Monitor or the display of websites, it's only videos that aren't displayed correctly. Could that be due to the graphic card? I thought about updating the drivers but since I did that when I installed Ubuntu and had the problem from the beginning I wonder what it could be.
I have a ASUS K52J.I tried cheese.It was initially upside down. Then I tried Video for linux device preferences.When I checked vertival flip, that fixed cheese. But it was still upside down in skype.I tried downloading skype from the webpage, and from synaptic.I tried running skype in sudo.I tried: export LIBV4LCONTROL_FLAGS=3 && L
D_PRELOAD=/usr/lib32/libv4l/v4l1compat.so skype but i get: ERROR: ld.so: object '/usr/lib32/libv4l/v4l1compat.so' from LD_PRELOAD cannot be preloaded: ignored
and I tried: export LIBV4LCONTROL_FLAGS=3 && LD_PRELOAD=/usr/libv4l/v4l1compat.so skype ERROR: ld.so: object '/usr/libv4l/v4l1compat.so' from LD_PRELOAD cannot be preloaded: ignored.I tried this:
LD_PRELOAD=/usr/lib32/libv4l/v4l1compat.so skype When skype loads up, i go to the options>video>test. The green light comes on by the built in webcam, then i get a segmentation fault and skype crashes: /usr/local/bin/skype: line 2:4055 Segmentation fault LD_PRELOAD=/usr/lib/libv4l/v4l1compat.so /usr/bin/skype
Then I tried:LD_PRELOAD=/usr/lib/libv4l/v4l1compat.so then running skype and i got the segmentation fault again.I may have missed some threads on this but everyone else seemed to be thanking someone for fixing their problem by now.Finally I tried threating my computer with a Windows installation. But I think both me and the computer knew it was a hollow threat,
I just installed Moonlight but except for the clock that starts running, buffering and connecting to the video server nothing else works.The screen stays grey and there is no sound. I thought it might work when I install Java applet, but also that doesn't fix.
