Ubuntu :: Terrible Sound Latency With Some Programs
May 15, 2010
It's an eMachines T2899 desktop, FIC AU31 motherboard, nForce2 chipset, AC97 sound (integrated), running Xubuntu 10.04 (wubi install), 2.6.32-22.I've got terrible sound latency (about one second between actions and sound) in some programs.Flash in both firefox and chrome (including ..... videos) and ZSNES (SNES emulator) are two offenders, as is Audacity.Videos played in the default "movie player" and VLC play with no delay, though.I've been told it could be an issue with the ALSA buffer size, or pulseaudio introducing latency... but I've no clue how to go about fixing it.Upon using the SNES9X emulator (which allows for choice of sound system)... Portaudio causes laggy emulation and bad sound latency. Open Sound System plays fine. SDL causes laggy emulation and bad sound latency. ALSA plays fine. Pulse Audio plays fine."sudo apt-get remove --purge pulseaudio" did nothing, so I reinstalled it just in case.
I'm finishing setting up my new computer.I'm installing ubuntu 10.04.The motherboard is a gigabyte GA-H61M-D2-B3When I plug the computer into my stereo, I get a horrible scratchy buzzing.How can I get rid of it?More info on hardware: Quote:lspci -v | less gives a lot of output, including this:Quote:
0:1b.0 Audio device: Intel Corporation Cougar Point High Definition Audio Controller (rev 05) Subsystem: Giga-byte Technology Device a002
So I recently installed Linux mint 64 bit version, and when I play certain songs, and it hits a certain bass, it crackles and pops. A lot. And I have tried a lot, but cannot figure it out. Any ideas? Musics fine on windows :/
After installing Catalyst with VA-API began a strange problem with the sound via HDMI. Prior to installing the sound worked fine. Platform: MSI E350IA-E45 with Radeon HD 6310 and AMD Zacate E350 Version of Catalyst 11.4. After installing the sound is playing with a terrible noise Sample: [URL]... I already tried all the audio outputs, but this does not solve the problem. The problem occurs only when the transmission of sound through HDMI.
I was wondering if there were any way of adding or changing where Rhythmbox gets its lyrics from as it never finds lyrics for any of the songs I listen to, making it a rather useless feature.If I recall correctly, Songbird was much better at actually getting hold of lyrics for songs I listen to, so is it possible to switch to whatever site Songbird (possibly a plugin for Songbird rather than it being native) gets its lyrics from? (Also, I just realised I posted this in the wrong section)
I'm on Ubuntu Karmic, and running Skype 2.0.0.72 -- since I couldn't get the latest version to work with my USB microphone. If I have Skype running, no other programs will produce sound (i.e. Amarok, VLC, flash in the browser, etc.). If any of those programs are active when I start Skype, Skype will fail to produce sound & won't work properly. Is there a way I can allow side-by-side usage of Skype and my other audio-producing programs, since all my other programs seem to get along just fine when it comes to sharing audio?
Audio Devices in Skype in case it will help: Sound In: USB Device 0x471:0x311 (hw:U0x4710x311,0) Sound Out: C-Media CMI8770 (plughw:CMI8770,0) Ringing: C-Media CMI8770 (plughw:CMI8770,0)
Again, both my current Skype configuration & sound in general programs works on my system -- they're just not playing well with each other.
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..
So there is sound but not from anything run thru jackaudio.Ardour and .9.5 hydrogen are not working i just upgraded a bunch of the programs using a ppa and now the jack ones are not working
After the latest update in testing, I found sound not to be working. I checked system config in KDE and found the wrong sound card set there. I changed it to the correct sound card, sound now works in some programs and not others (IE, Dragon Player and Amarok have sound, Kaffeine and Iceweasel do not).Sound does not work through the on board sound card.System beep sounds (through the onboard speaker) also fail to work.I've had similar problems in the past due to the inability to turn off the onboard sound, alsaconf has always fixed them, however debian has removed alsaconf from alsa-utils.
it's been a LONG time since I've used Fedora (I think 6 was the last I used) and I decided to check things out. Installed the LiveCD KDE respin x86_64 version. Once the installation was done, I installed the yum fastest mirror plugin, then did a yum update. I then yum installed firefox, and used the autoten script to install Flash-plugin, Mp3-codecs, Dvd-codecs, and All-codecs. I then installed amarok and tried playing a song.There was no sound, and the slider moved at least twice as fast as it should have. I then attempted to play a video file with VLC. The video played fine, but there was still no sound. Firefox seems to be the only program that plays sound properly, as both ..... and pandora play fine. Konqueror however does not play sound on ......This seems to me like a 64-bit related issue since I think firefox has all the 32 bit libraries for flash to work, but like I said, I've been out of this scene for a while now.
I reinstalled backtrack, and now have it working, except, it only works in a few things, there are many programs that don't recognize JACK (for instance, Firefox).Now, I have downloaded and installed libjackasyn0 which allows me to run,However I am unsure of how to make that work. Does anyone have any ideas of how I can enable libio2jack0, or does anyone have any other ideas as to how I might accomplish this?
II installed flashplayer by every different method I can so far, and all of them have the same problem. This problem presents itself, for example, while playing a video on ...... As the video loads, flashplayer is fine, but as soon as it starts playing, the browser tab begins to run at roughly 1 frame per 10 seconds. When I turn the browser priority to maximum in System Monitor, it improves slightly, going to about 1 frame per second. The strange part is, my CPU and memory usage barely spike at all, to less than 30%. This happens regardless of browser (have tried iceweisel and chrome). It happens with hardware acceleration on, and off. I have tried installing flashplayer from the tar.gz on the adobe website, from the repository (all three packages), and manually placing the plugin in the browser myself. The issue presents itself the same every time.
My system specs are: 1.83GHz duel core intel centrino processor, 3GB RAM, ATI Mobility Radeon HD 2600. Nothing fancy, but flash player performs as flawlessly as flashplayer can under windows (and also performed well in my previous Ubuntu 10.04LL install).
Ok first off, I love debian, but on my new notebook I am getting a little frustrated with the terrible, video performance.Direct rendering is enabled on both systems, and openGL is working (I can if I wanted to use compiz etc...) fine on both systems, just running slow on debian.
I have tried Lenny, Squeeze and Sid, I have compiled the intel driver (and Mesa3D) from git and got it working (I am sure its working because its given me a slight boost), I ahve also tried building the latest stable (and RC2) kernel.If I install ubuntu 9.10 I get pretty decent 3D performance, its not ground breaking, but hey its an intel chipset so I am not expecting to kick the latest nvidia / ati card's backside.I really dont want to use ubuntu, I find it unstable when compaired to debian, but I also want to be able to play the odd game when I am bored, and at the moment I just cant do that under debian
I am trying to get networking up on an old PII which I have successfully installed with FC4. There is a link and activity on the onboard interface because I see the indicator lights. The controller is a 3Com PCI 3c905 Boomerang 100baseTx @ 0xdc80.The only message returned by dmesg about eth0 is "Dropping NETIF_F_SG since no checksum feature."The driver module, 3c59x, is loaded as well as the mii module that depends on it.There is something about "unknown parameter`irq'" in the dmesg text regarding the driver.I noticed that eth0 is sharing an IRQ with the UHCI Host Controller.That should not be a problem, but it should not be necessary. And I could do away with USB if this is a conflict and that is the easiest way to solve it.When I drop to console at runlevel 3, and call dhclient, which is installed, I get a message telling me there is no reply to the dhcp request.I don't think the problem is on the router/switch side.
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?
Everything was fine last night, but this morning I signed into my Squeeze box and found that website play audio fine, Hulu Desktop works, some games work, etc. but Rhythmbox, VLC, Totem, and others don't . It all started with an attempt to diagnose a lack of sound in TVtime.
we are setuping high-performance web farm with 4 ubuntu servers (all 10.14 LTS 64bit, i5Core CPU, 16GB Ram). One server is "database" server with mysql installed, three servers are "webservers" with tomcat installed. All three webservers have public IP and are connected directly to internet by eth0 (onboard network card) and are connected to switch that is connected to database server by eth1 (pci network card). All servers has stardard instalation with no special modules/programes installed.
Web servers are already under load, but only on about 10 requests/minute. After several hours in production, strange thing happened - one of the web servers (each time another one, so it is happening to all of them but not at once) starts to have pings to database (that is connected directly on LAN) = 100ms (other two servers still has like 0,02ms). Pings stay high until we do /etc/init.d/networking restart, after that it is fixed and pins are again low again. Another strange think is, that when we let ping running for some time, it is slowly dropping from 100ms to 1 ms and then again jumps to 100ms (exactly to 100ms always) and again starts dropping - so it is cycling over and over again (one cycle takes about 2 minutes).
We were trying reconfigure network, play with switch (the same situation was happening even without switch when there was only one webserver and one database server directly connected), disable IPv6 but nothing helped. The only thing that we discovered is that it has to be caused by network configuration.Do you have any idea what can cause it? We went through systems logs but found nothing suspicious (at least according to our understanding).
I'm getting close to ordering the components for a new machine based on the AMD Deneb quad core and had one last question.I'd like to try a little careful overclocking, not only for the performance increase but also to learn how. Nothing extreme, no gaming, just whatever I can get with good stability with the stock heatsink and fan.I was going to get 8GB on 2x4GB strips but they are all CAS latency 9. The MB has 4 slots for a total of 16GB capacity. Would I be better off going with 4x2GB strips and try to get a lower latency strip like maybe 7?
I just installed Maverick Studio on a new hard drive, and am using an NVIDIA GeForce 7300 LE GPU. If I boot into the 2.6.35-22-generic kernel, everything runs fine, but if I try to boot into either the 2.6.35-20-Low Latency, or 2.6.33-29-Realtime kernels (installed from Synaptic), the computer boots straight to a command prompt instead of the desktop. Does anybody know what causes this? I need to be able to use one of these kernels for doing music production.
I'm experiencing massive latency/unreachable problems on my Linux machine. It's true for all network connections, here's an example of me trying to ping my router:
PING 192.168.0.1 (192.168.0.1) 56(84) bytes of data. 64 bytes from 192.168.0.1: icmp_req=1 ttl=64 time=15115 ms 64 bytes from 192.168.0.1: icmp_req=2 ttl=64 time=14107 ms 64 bytes from 192.168.0.1: icmp_req=3 ttl=64 time=13107 ms 64 bytes from 192.168.0.1: icmp_req=4 ttl=64 time=12107 ms 64 bytes from 192.168.0.1: icmp_req=5 ttl=64 time=11108 ms
[Code]...
I've tried now with both the maverick default kernel and 2.6.37-rc5 kernel (both 64 bit), same result. If I take the card up and down (ifup, ifdown) performance is restored for a little while, then it's back. I've tried changing cable, network card and router port but no luck.
As I am trying to understand if there are any advantages using a kernel optimized to have low latency for the desktop, it would very helpful if anyone using one could give me his opinion. I read about the liquorix kernel and found a controversy and used google to find more information.
I tend to use commands like 'aptitude search $something' or 'dpkg -S /usr/bin/command' (some command/variable in both) or 'apt-file search $something' and all/or many of its brethen. I do run updatedb every now and then but that command is for the overall health of the system similar to tracker perhaps (but not running continously like tracker and the daemon).
What I'm looking for is, if there is a way to get the package list (installed and otherwise) updated aggressively so that whenever I use any combination of aptitude or dpkg I get better response from the system. From what little I understand, aptitude or dpkg or somewhere there would be some sort of index/database where the current state of package availability and system state would be recorded. If there is a way that this could be improved upon would be nice to know. If there is some experimental package or road which the debian folks are looking for in the future so this latency can come down.
is there a realtime or low-latency kernel in a repository somewhere for OpenSUSE 11.4? I know I can just compile a rt kernel, but that's a bit tedious and I'd like to avoid it if possible.
I have a four-cores machine (core1,core2, core3, core4 ). I want to test the communication or latency between two cores (for example, core1 and core2; core3 and core4). Does anyone know how to write a code to test it under linux operating system?
I'm looking for a program that can measure disk latency. I would prefer one that could do it on a raw device. Also reporting average and max latency would be a plus.
