Slackware :: Excessive Audio Buffering Required - Distortion Still Remains
Mar 25, 2010
I use my system as my stereo. It's the only thing I listen to. For quite some time now though, I have had a problem with audio not being properly played. What I get is what sounds like reverberation in the audio feed. I found that increasing the amount of time for the feeds to be buffered helps, but only partially.
I also installed another parallel system in this very same computer (on a different disk) which initially didn't have this problem. But then I did an upgrade and the problem became apparent on that system also. However after having done a couple of reboots, I noticed the problem disappeared. Now that system running is running clean as it was initially.
This may be an issue with my nVidia drivers. I'm not sure. Because I noticed problems on the second parallel system after attempting to install the proprietary nVidia graphics driver, which had numerous unpleasant side effects. So I removed it. But the problem didn't go away immediately. Only after I had rebooted a number of times did the sound begin to play as it would normally be expected to.
My primary system, the one from which I am now posting this runs KDE. But on the parallel system, due to a much smaller disk space, I am running XFCE. So this isn't a KDE-only issue.
I've been messing around with fail2ban regex and heard that you can get better performance by disabling syslogd buffering. By better performance I mean that fail2ban can detect more login failures per second than with syslogd buffering turned on.How do you disable syslogd buffering
Quote: The precompiled Slackware kernels are available in the /kernels directory on the Slackware CD-ROM or on the FTP site in the main Slackware directory. I am unable to reach it, what's the proper login?
When I was running Windows OS on my laptop I was able to buffer and pause movies I watch on Dvix. Now that I'm running Ubuntu, I cannot pause the movie anymore. Whenever I pause it, I have to watch the movie from the beginning. Also, I cannot let the movie buffer to completion.
After updating my system today, sound stopped working. VLC said I should update alsa-lib. Slackbuilds had none to offer, so I got the sources from http://www.alsa-project.org/main/index.php/Main_Page. It compiled and installed without problems, but the error from VLC states the same. Is my system the only one affected by the update, and how do I fix it?
I am running Slackware64-13.1 on my laptop. I need to install skype on it. Searching this forum suggests that I install Alien Bob's multilib [URL] However, skype is the only 32-bit package I need and I will not need to compile any 32-bit software. So what is the minimal multilib install (the minimal set of 32-bit libraries) that make it possible for the 32-bit Skype to run on a 64-bit system? Will running
Code:
ldd /usr/bin/skype
on my 32-bit desktop machine provide me that minimal list of 32-bit packages? Also, will the installation of these libraries somehow interefere with the original 64-bit system?
Can someone please tell me what packages are required for compiling source on Slack 13? Something is missing in my box and I get errors, I can't figure out what it is.
I keep time sheet entries at work in an sqlite database called 'timesheet'. I have a shell script called 'today' which queries for all timesheet entries which are less than 24 hours old; it looks like this:
I understand that the linux pipe is a buffer and that any data written to it will stay there until it is read, and if the max capacity of the buffer is reached, any additional writes will block (by default).
HOWEVER, the behavior of the pipeline below suggest that the write operations are buffered/cached before ever being written to the pipe on the client side here is write.sh, which creates 1000 byte string and writes it 100 times to stdout... the idea being that it'll block as soon as the 64kb linux pipe size is reached:
[Code]...
This is not what I was expecting: I was expected that once the capacity was reached, any reads would be followed immediately by a write to take advantage of the freed space. Instead, the blocked write operation seems to wait for some random amount of time/space to free until it unblocks and writes.
Are there any quick and easy ways to find all of the dependencies required for a package to be installed, so that we dont have to spent a lot of time searching for each package or downloading them individually?
I'm trying to bring my Slackware system back to life as my XP HDD is dying... I've got everything working except for my audio. I got a new motherboard (ASRock P43DE3) and it has a VIA VT1708S as the onboard audio. Is there any way I can get this working without rebuilding the kernel?
Just got Ubuntu 10.04, Ive had some experience before with it but this is the first time I have completely removed Windows (7) from my system....
Okay, short and sweet, I have a Gateway Lt31 series netbook, It has a {Ati X1200 Graphics/video card}. I get really bad distortion on the top of my screen at all times, and at others the entire screen becomes Distorted. Sometimes the text becomes no mre than mere blurs and I cant see particular letters ( I cant see the "v,n, or o" right now).
Im downloading the 9.10 iso now and will downgrade if necessary
I can barely use the live session CD of Ubuntu 11.04 because,everything gets corrupted,i cant open new windows because it starts to get horrible, like if i had a graphics problem, managed somehow to open Mozilla and write this, but its impossible to do anything else that needs to open more windows layers...
I never had this problem with ubuntu before... my graphics are intel extreme graphics 2.i cant even use the terminal because it is in few words... invisible, unless I move it but then, disappears.I can work normally using windows. Also i have ubuntu karmic live cd and works perfectly.
F12 current updates. The Gnome Desktop Background images are compressed in the horizontal axis enough to make a cessna 182 look like a disney cartoon. I am running 1280X1084 75 hertz update rate. The Gnome Image Viewer gives a correct image. The image I am running had to be stretched to fill the screen. I suspect the stretching algorithm is at fault. Is this a bug that need reporting?
I upgraded via the terminal from 9.10 to 10.04 and after the upgrade I've been having these weird horizontal screen distortions. I was wondering if there will be a fix to this, and if I'm the only one experiencing this.
I am using Natty and its favoring me with too much of screen and cpu overloading problems.After some usage with movies or browsing, it gets a distortion and whole horizontal lines appear on the screen like a 8BIT distorted Video game. The background actually runs good, since i tried playing mp3 and got the error after wards. After distortion, the windows start flicker and changing. Is there any way to stop this?Second thing,The cpu easily becomes full while mounting drives or surfing itself.
I upgraded via yum to 2.6.32.9-67 today and rebooted.
Running Google Picasa under wine is pretty much unusable. A quick reboot to the previous 2.6.31 kernel provided via the Fedora repositories previously solved my symptoms.
I don't think the problem is limited to Picasa but haven't done anything scientific to show what the problem could be.
Because I run on a trusty six year old laptop I visually monitor the system with the System Monitor applet. Usually slowness is i/o wait while the disk is retrieving information but on 2.6.32 it's pegged as system time eating up my CPU.
Before I report this in bugzilla, can anyone else tell me what their experiences with 2.6.32-9.67 have been?
Also, are there any fine-grained performance monitor tools that might explain what's going on to peg the CPU so high? top just shows Picasa running.. and it can be a hog doing background work at times. If it is, a reboot just continues the cpu needs not eliminates them as in my case.
i'm using a m-audio delta 44 card and if i play anything through vlc it sounds great. however my problem is using flash, any sound through flash sounds terrible. all distorted, glitchy and crackly and with lots of white noise mixed in for good measure.i feel like i'm going round in circles now and i'm at the limits of my knowledge. i've tried all the packages i can think of for flash, reinstalling oss numerous times and a different browser but no lucki've been tearing my hair out all day..
I have a 64bit desktop and 64bit laptop. I upgraded both to 10.10 and they both have the same problem with compiz. Even though I selected the cylinder distortion, the rotating desktops will not deform to a cylinder unless I select "Wallpaper" in compiz but when I do that, the cylinder is completely transparent AND objects (like windows or bouncing/squishing icons in AWN appear not to refresh. Like a window will not disappear after closing.
As an aside, I have four different wallpapers selected for the four different desktops, but none of them display when I select "Wallpaper" in compiz, I just get the transparent cylinder.
If I deselect "Wallpaper" in compiz, the problem with the refresh disappears immediately, as does the transparent wallpapers but the cylinder becomes disabled and I am left with a cube with a single wallpaper and no ability to decrease opacity during rotation.
This has happened with both my desktop and laptop. I have tried uninstalling all compiz components in Synaptic Package Manager and adding them back one at a time in case I added some conflicting components but this doesn't seem to help.
I did not change settings in the updates, so I have to assume that the problem has something to do with a bug in Compiz. The two computers have different video cards and the drivers are up to date, so I'm at a loss.
Has anyone else found this problem? Has anyone been able to display the cylinder distortion with four desktops with different wallpapers?
Just installed Fedora 14. My HDD LED is flickering constantly about 7x a second. This only happens after I start X-windows and continues if I log out. Top shows dbus-daemon at 15% CPU. I'm sure this is causing it as it only starts after X-windows.
i'm looking for a webcam viewer/recorder that can remove the perspective distortion. (ie a square looked at from an angle becomes a trapezium). Mplayer can remove the distortion but it can only view the webcam, not record to file. Mencoder can record, but not view. But I need to view and record simultaneously (sigh). ...
Just noticed from the "top" command that one of my least heavily used box is swapping excessivly by a program called setroubleshootd. Following is the top section of the "top" command sorted by Swap used for both boxes. Also tried checking it out to see if there's a "service setroubleshootd restart" but when I checked the status I got the following.
Code: [root]# service setroubleshootd status setroubleshootd: unrecognized service Lightly loaded box with lots of swapping
For some reason, if I leave my Linux box running for several days, the swap space and RAM slowly fill up until my system is so slow that it takes around 15 seconds just to open a new tab if Firefox (Iceweasel, specifically). I have 512GB RAM and almost a gig of swap; how on earth does it fill up so much? Even if I close all my programs, there's still over 600MB swap used and all RAM is full. I've included a screenshot of 'top' running just about two minutes after I closed all my running programs.
(Before I closed it, I had only 71MB swap free.) I know that Linux is supposed to make good usage of RAM, but isn't this over the top? Is there a way to force it to use only required memory with no or little extras kept in RAM? Just thought I'd add in the fact that I'm running Xfce as opposed to KDE or GNOME in an attempt to have a smoother running system on my old hardware. Also, what's the "VIRT" column?
When I ps -e, I see a whole bunch of processes, many more that when I ran Slackware.Is there a list of processess I can look at to see what they are and what ones I dont need, instead of googling each one and getting some cryptic explanation?
When trying to "Leave" the system (either via the small button on the lower right of the taskbar or by right clicking on the Desktop and selecting "Leave") the logout / shutdown / restart screen comes up. I have the "Logout" desktop effect activated, which is supposed to desaturated the background when the Leave screen appears. However, instead of simply greying out the background, the image on the desktop and the rest of the screen also gets slightly distorted, with seemingly random distortion effects cropping up all over the place (e.g. horizontal lines or large blurs).
These distortions are different every time the Leave screen comes up. The Leave screen itself is displayed fine, and apart from the dodgy background I have no other issues with the whole process (the system shuts down or restarts properly according to my choice). I am using the Radeon drivers, and all other desktop effects I have on (Magic lamb, cover switch, present windows, etc) work fine and without a hitch. It's only the Logout effect that seems to glitch. Are the distortions intentionally created by the effect in order to emphasize the focus on the Leave screen?
I'm using Firefox 3.6.12 on Fedora 14 (64 bit) and have noticed that after using it for a while (and/or leaving the browser open for hours at a time), it becomes almost unusably slow and uses an excessive amount of memory. For example, any of the following can cause Firefox to temporarily (for 5 to 10 seconds or so) stop responding:
- clicking on a link - opening or closing a tab - scrolling It will always start responding again, sometimes after the window darkens (to indicate that it's not responding) but it's so bad that it can't really be used. Closing it and opening it (restoring the tabs) again fixes it for a while, but the problem recurs. Regarding the memory usage, it was using 850MB (according to System Monitor) when I closed it, and having re-opened it and restored the tabs, it's now using under 200MB (but appears to be rising).
Another way that this manifests itself is that when trying to watch a Flash video (like iPlayer), it pauses for a second every 30 seconds or so, making it very annoying to watch them (I've switched to Chrome for this now, and am tempted to switch for general browsing, but like the plugins in Firefox).Is anyone else having these issues, and does anyone have any suggestions on how to fix it?
At times, the disk I/O will go through the roof and cause the system to slow to a crawl. X becomes really slow and can go completely unresponsive, dropping all keyboard input, preventing me from restarting X. Sometimes I will switch to a virtual terminal to log in and run iotop to check what is using all the I/O, but it will be so I/O bound that the login times out. Sometimes I do manage to get in and can run iotop and then it is a matter of waiting 10 minutes or so for python to load up. Usually by this time, whatever was causing the slowdown has finished and so I don't even know what the problem is. Other times it never recovers (I once left it over night, since it was at the end of my work day and just went home)
This is my work computer so it is very inconvenient to have to wait for this I/O blockage or lose all my work rebooting. I thought it was due to swapping, so I disabled swap, but that hasn't helped. I'm running the cfq I/O scheduler, but I've tried both deadline and noop.
Also, is there a way to disable the login timeout so I can at least get logged in to the box from the console when this happens?
