I have the slight, high-pitched hissing frequency when ever I play back audio.I know other people have experienced this as well, but the threads were in a development section of the forum and are no longer open. Has anyone has the same issue yet found a solution?

View 4 Replies View RelatedI am getting a high pitched ringing sound coming from my speakers and headphones on 9.10.Does anyone have any ideas what is causing this problem and how to fix it? It is really annoying after awhile and is headache inducing.I've tried switching from PulseAudio and ALSA with no changes.
View 1 Replies View RelatedI upgraded to 11.04 today, and ever since the upgrade my speakers (and headphones; any audio device) emit a high-pitched shriek when connected to the computer. This only happens after I enter my password on the login screen, and only in Ubuntu. There's no problem when I boot Windows.
The sound is very high pitched and my speakers play no other generated sounds while emitting this static. Obviously, I'd like to be able to have sound and listen to my music, so this needs to be fixed.
I am looking for a daemon that will set the CPU to lower frequency if its temperature is going too high. I used an application like this in Windows.

My PC - intel i3, integrated 4500 vga and 4GB RAM, Ubuntu 11.04 64bit. CPU usage is around 30-70% and disk load is low.
Typical performance tweaks like "skip loops - all" and read buffer size doesn't affect current condition. In Ubuntu 10.10 everything worked flawlessly.
PS. whether 4500 gpu acceleration should work in Ubuntu 11.04 by default? I can't set it up...
Using Ubuntu 10.04.My fonts looked different today. Only slightly different. So I went into the appearance preferences to try to figure it out.In, Systems->Preferences->Appearance, click the "Fonts" tab and for "Rendering" select "Subpixel smoothing (LCDs)".Then click "Details". For hinting I choose "Full". Then I close the "Font Rendering Details" dialog box. And close the "Appearance Preferences" dialog box.
My problem is that my system won't keep my "Subpixel smoothing (LCDs)" font Hinting setting on "Full". It keeps changing it back to "Slight". When I go back into the settings one thing I notice that you can see in the picture is that for "Rendering" they all have the minus sign. Then when I re-click on "Subpixel smoothing (LCDs)" it shows up as "slight".
I'm using currently ubuntu 10.10. Having a nvidia gt220 with the proprietary drivers. I used compiz for a while. It works quite well, with vsync on and so on. But one thing bothers me all the time: In any opengl program (like a game or the unigen benchmarks) or on video playback (no matter if its the default video player, xbmc or what ever) I see some kind of stutter. About every second or so it jumps one frame forward and then two back. Till the next second it plays fluid.
To be able to observe this easily you need a video (or a opengl scene) where the whole screen scrolls in a medium speed but smooth. Than you can observ how it "jumps" every second. If the scrolling is too slow you wont observe it. Now, if I turn composite off this disapears. All play fluid. Ofcourse I get tearing as long as I do not also disable the composite extension in the xorg.conf, but this is another story. Is there a possibility to fix this stuttering with compiz active? Cause I use this pc to watch movies quite often so this would render compiz unusable.
So, "unable to update .IECauthority hit me yesterday in a big way. After trying all sorts of suggested remedies in the [solved] and unsolved threads, it became quite evident that the chown and chmod would not work coz ubuntu cant find the "file or directory specified" by .IECauthority. {pardon the n00bspeak}
So i looked around for the "new user" option, i.e. creating a new user so i can log in. That worked. i got to terminal and used sudo adduser guest and now i can at least log in but, predictably i cant access the files of my home directory that was under my "owner" login.
How i can access these files as my new "guest" user alias?
I feel like im so close to beating this friggin .IECauthority error though i am well aware i brought all this misery upon myself coz i just had to have the extra skins for this particular screenlet...
When I'm in OpenBox, I often have a termianl (lxterminal) open in the background. The terminals responds quickly when logged in as my standard user. If I, however, use su to switch to root, there's about a 2 or 3 second delay on the output for any command I type. This delay goes away if I type another character or tap the spacebar. That input is read as normal -- I've accidentally answered 'y' to prompts before.

Switching to and from insert mode in Vim is no longer instantaneous since I use tmux. After pressing Esc in insert mode, it takes a noticeable amount of time to actually get out of insert mode. After pressing Esc and any other key afterwards the switch is immediate, and the command for the key pressed after Esc is executed. Any idea what might cause this?The Vim configuration is not the problem as the delay does not occur when I run Vim outside tmux, so this is probably related to tmux somehow. I use gnome-terminal btw.
Also worth noting, it seems I can not define key bindings in tmux for Esc, my plan was to bind Esc to:bind Escape send-keys.Alas, it seems binding anything to Esc for tmux does not work. The same problem occurs in screen as well.
I upgraded from Slackware 64 13.1 to Slackware 64 13.37 a week or so ago. I am now having a perceptible delay of a few seconds when launching commands from the command line, say for example: screen -R.

In C, I want to make a program that will take a file and replace it with a file that's nearly the same but with some minor changes. Also, I would like to point out that I'm still fairly much a beginner with C. As for an example of the file, I want to take something like this:
Code:
Random Crap
More Random Crap
Even More
Something That Changes XXXXX
[code]....
I figured the best way to go about doing this was to open the file and a blank file, read the original bit by bit and when it gets to the point that needs to be changed exchange the part that needs to be changed with what it should be changed to, delete the original file, and rename the new one to the correct name. So the first problem I've run into (and I'll probably have more) is that when I'm trying to read stuff from the original file, my program doesn't seem to be finding the original. I'm sure much of my problems will be just from not knowing how to use the C functions so bear with me. Right now I have the following:
Code:
#include <stdio.h>
#include <string.h>
#include <stdlib.h>
[code]...
And when I try to run it I get the following:
Code:
Died Here: No such file or directory
Segmentation fault
Right now the length of 50 was just a random test length. Pretty much I was just trying to get it to read anything from the file. In the end I'm going to want it to read the entire file bit by bit, but at the moment I can't seem to get it to read anything.
Can anyone point me in the direction of how to set the screen to 60 as I find I get sore eyes. Sorry I don't know the tech jargon.

It says on guides that it will ask me to reboot but it doesn't, so I manually did it and put the CPU Frequency Monitor on my taskbar. It does not have the options like it shows in the screenshots to set my CPU frequency..
I'm looking for a CPU frequency applet which monitors the frequency of ALL CPUs at once.
Does it exist such applet?
I wanted to be able to see the frequency my cpu is running at

I'm running ubuntu 11.04 with a Pentium T2060 1.6ghz. Ubuntu only lets it go up to 1.2ghz. And no its not a cpu power saving feature. In Windows it gets to 1.6ghz fine
View 1 Replies View RelatedI have the CPU frequency scaling applet in the panel and it worked fine when I had 8.10 but now that I'm using Karmic, I cant get it to work correctly!
It won't change the speed to what I tell it to. I click on a different speed and it does nothing.
The CPU spins too slowly and videos lag or it spins at full speed and overheats even though I have nothing open! I really need to be able to adjust it.
how to fix the CPU Frequency Monitor 0.4.0~rc2 for AWN 0.4.0~rc2-rewrite-bzr674-karmic1-1 so that you can actually scale CPU frequencies?

I am new to ubuntu. I have just one question, everytime I reboot my laptop the CPU Frequency Scaling Monitor goes back to "On Demand." Why is that and can I also set it so it stays on Performance.
View 4 Replies View RelatedI'm a bit new in Ubuntu, but I am about to get a hang in it. I have previous use karmic koala and the version before that (cant remember the name for that) on my old computer and now I am using ubuntu 10.4 on my new computer. Ever since I installed Ubuntu for the first time, I noticed that the sound quality wasn't... the best. There isn't so much wrong with it, but like that this example. I played a FLAC file with some headphones (thru Ubuntu) and the sound quality sucked.. and then I played a mp3 file (with an ipod) and the sound quality was much much much better than the FLAC file.
I tired to play an HD movie over ....., where on Windows XP it sounds perfect, but with Ubuntu it kinda sux. The MP3 (Ipod / windows XP) is still better, than anything that is being played in Ubuntu. This is with almost every sound format I have tried. No matter if I play it with Rythmbox or vlc or some other player, the sound is wrong. I cant describe how it sounds.. but it is like it is going with a low frequency... or it is compress some how... Ever since I tried Ubuntu for the first time Ive noticed that something was wrong, but couldn't never really put my finger on it. I have dual-booted with windows XP and the sound in XP is really, really good compared to Ubuntu.
After some updates system doesnt login.In the monitor displays out of frequency.
View 2 Replies View RelatedI am doing a project on how power consumption of a CPU can be improved by underclocking the lower P-states and overclocking the highest p-state.In this way you can increase both the performance of the chip and it's average power usage (assuming you don't run the chip at 100% 24/7).
To do this project I need to be able to change the voltage and frequency of the chip for all of the different p-states of the chip. On Windows I can use k10stat, RMClock or AMD Overdrive.
What can I use in Linux? I found k10ctl, but it always complained about not being able to find /dev/cpu/0, so I looked in /dev and noticed that their isn't even a cpu directory in there!
I have a moderate amount of experience so I don't mind changing kernels or doing other hard tasks to get this to work.
A week ago, after some daily update, my cpu frequency monitor stopped working, i'm stuck with 800 mhz now Yesterday i upgraded to 10.10 version, but this applet still doesn't work. or maybe there are alternative programs that change cpu frequency as well? I was looking in software center, but found only monitors so far.
View 1 Replies View RelatedI'm using the latest kernel and after I boot up my computer the cpu governor changes from the fastest setting (2ghz) to the slowest setting (800mhz), and gets stuck there. Theres no obvious way to change the setting, the gnome applet to change the cpu frequency doesn't work - I've also tried to change the setting manually through the /sys/ directory but to no avail.
There was a suggestion to fallback on an older kernel, but my older kernels suffer from the same bug.Does anybody have any ideas? I can provide more information on request.
I'm not sure if this is an issue with Ubuntu or with the BIOS. Basically when I start up my computer, the ondemand governor seems to work just fine (ranging from 800 MHz to 2200 MHz). However after some indeterminate amount of time, it will get stuck at 800 MHz and I'm not able to figure out how to get it to scale properly again.
When I restart my computer, it acts normal again for some time before locking in at the lowest frequency.
It seems like it may be related to this post: [URL]. The last post in that thread mentioned that it could be related to the temperature, that may be the case in my situation. Even if the temperature is low after it locks to the lowest frequency, it won't increase the speed as needed
My question is, is there any way to override this and let the CPU continue to run at higher frequencies once it locks down to the lowest frequency? My computer doesn't feel like it's getting that hot (it's a laptop), and I'd like to not have to be able to restart it every time this happens.
I've recently reinstalled a computer with 10.04 for my parents to use, and it worked fine at mine, but after transporting it to theirs and hooking it up to their existing monitor it doesn't seem to work anymore!Well, it boots and I hear it login but I don't get a splash screen and at some point between the bios and the login sound it comes up with Frequency out of Range. On the warning message it displays a frequency of "72.9 kHz / 90.2 Hz" but in the monitor settings its reporting that its operating at horizontal 64,0 kHz and vertical 60.0 Hz. I also don't get any splash screen when starting up, just a flashing _ before the monitor stops things
What I can do however is drop into a the tty console (alt+ctrl+1) and login to the shell but don't really know what things to change from there.Having googled things a bit I've found references to xorg.conf but there's no such thing on my system so I can't edit that to fix this. Likewise I also have found references to fiddling with grub to get into the recovery, but grub doesn't even appear when I boot and I don't know what to press to get it to drop into its menu...
This is really urgent as I need to go home tomorrow at the latest and I want to get my parents system working before then. I also have no spare monitors here and I didn't think to bring with me a liveCD to fiddle with things (only a UNR netbook which I'm posting this from), so the console is the only access I have to the machine.Some specs: Ubuntu 10.04. ATi Radeon 9100 IGP, no proprietary drivers are installed. The monitor is an old CRT that still works beautifully and whose replacement is not an option.
