I haven't do any updates so it shouldn't be anything wrong with the system...Even after restarting my comp, it still won't work.I was plugging in my earphones to the jack last night as I didn't want to disturb my family while watching starcraft 2 commentaries...So this morning i plug it out and wanted to use my speaker and it don't work anymore...it was working fine all the time...so is there any way using the earphone might have cause the problem?
Ubuntu and I'm using the latest stable version. Yesterday I had my sound working, but today my sound has stopped working.I've taken the following steps without success:System -> Administrator -> Hardware Devices (finds nothing)
I'm running 64-bit Ubuntu 11.04. I recently updated virtual box and wine. I also installed the expansion kit for the virtual box. Now Ubuntu doesn't read my sound card. I tried reinstalling alsa and pulseaudio but that did not help.
aplay -l shows no sound cards.
I have a Realtek ALC892 8-Channel HD Audio sound card.
I have Fedora 12 and I am only running ALSA (not PulseAudio) for my sound.[URL}.. It was working fine until one day I noticed I'm getting no sound. There have been countless Fedora updates (prompted by the Fedora updater) so I'm suspecting some update horsed it up somewhere.
So when I go into System > Preferences > Sound it just hangs waiting for the sound system to respond. The sound card works fine because when I dual boot to Windows XP I do indeed get sound and I haven't changed anything since it worked before under Fedora. Everything is unmuted and turned up in my alsamixer settings.
I am running Ubuntu 9.10 on an HP dc5100MT workstation. Sound works nearly all the time, but once in a while, the sound stops and I have no idea why. The channel is not muted, the volume is 100%, and not even rebooting fixes it. It will just start working on its own.Under the Sound Preferences panel, the output volume is 100%. The channel is not muted. I can get sound out of the internal speaker by changing the connector to "Analog Output (LFE) / No Amplifier", but not out of the "Analog Output / Amplifier" which is the green sound cable plugged into the sound card.I only use this machine as a video player using VLCNothing else.I would like to know some tricks to isolate and troubleshoot this when it happens.
I'm using Ubuntu and my sound was working fine and then suddenly it just stopped working.
It does however, have odd spells where its working (for like 2 minutes) but those spells are few and far between. So basically the sound is not working.
When it isn't working my speaker seem to be making these hissing/screeching noises.
I've tried looking up on Google on how to fix it, i.e. running terminals, etc. but still haven't come round to fixing it. Could someone explain to me how to fix the sound please?
And no, the speakers aren't on mute. I checked volume control and everything is full.
Summary: Laptop: Acer OS: Ubuntu 9.something Sound card: hda-intel Problem: Sound not working
I recently installed ubuntu 10.10 (Maverick) on my new laptop. Sound was working just fine until today morning, when all of a sudden no sound would come out of my system. It is not a hardware problem as sound is working fine on windows.
When originally installing 11.04 I had problems getting my Ralink 5390 wireless card to work.
Today my computer froze completely and I had to turn it off via the power switch. When I turned it back on, wireless was no longer recognized! My iPod can connect to the network just fine, so it must be an Ubuntu problem. There are no problems with my ethernet connection either.
I researched this and found several threads about blocking and unblocking wireless devices using the rfkill command. Well, unfortunately for me the rfkill command doesn't work. When I type sudo rfkill list or sudo rfkill unblock all, nothing happens; it just returns me to my bash prompt. I even tried uninstalling and reinstalling rfkill...nothing.
After performing an update that the OS told me to do, I no longer have any sound available in any application. I tried rebooting into older versions of 9.10 and the problem persists. It is not a hardware issue, because the sound is fine in Windows.
So I was watching a video, and I changed the volume, and then the sound cut out, and it has not come back. No sound can be heard, from flash nor from files; through my laptop speakers nor my external speakers
I believe I heard the KDE fanfare when I booted up the first time after installation, but now - nothing.from lspci:00:1b.0 Audio device: Intel Corporation 82801I (ICH9 Family) HD Audio Controller (rev 02)I tried some of the stuff from here http://ubuntuforums.org/archive/index.php/t-940689.html Adding the boot option: kopt=irqpoll to grub- and the three lines:
I'm running on Debian Testing, and I just distro-upgraded from Squeeze just a month ago. When I did, I had some strange sound and video problems. For the sake of this topic I'm just talking about the sound ones. Back then, my sound would only work as root, otherwise without any visible errors, I would play sound files and no audio would come out. I'm aware that this usually means that my user is not a member of the 'audio' group, but I did and Ihave confirmed it and all of my users are. Then, suddenly my sound inexplicably started working again, so I took it as it was. However two hours ago it disappeared again. The important information here is that nothing I did as a user could have effected it. All I did was let a video file buffer, write a text file to my documents, and send an email.
According to Alsamixer my sound card is HDA Intel & my chip is SigmaTel STAC9200. When I upgraded to Wheezy, the terminal told me that I would need to install proprietary drivers to get my sound (and especially) video working, however every tutorial I've found on how to do this seems to dead-end for my computer on the current testing branch of Debian.
when i tried to watch a videos video today, i noticed that i suddenly didn't have sound anymore just yesterday, it still worked fine. changing the video volume didn't do anything, so i looked at the mixer icon in the taskbar - and noticed to my surprise that it was suddenly set to mute, without me ever having touched it!
i set it back to full volume, but still nothing. i then tried to play ordinary videos in nmy video layer, but also there - no sound! so it's not limited to flash videos. the sound test in yast doesn't play any sound, either, it produced just a very short popping sound, that's all. i tried turning off pulse audio there, but that didn't change anything, so i turned it on again (i use pulse audio for sound).
next, i tried the kde control panel, but got no test sound either, just again the very short popping sound on htting the test button and nothing else. i've even tried switching the preference from xine (which i normally use) to gstreamer, but that didn't change anything either. then i did a reboot and tried things again, but no change. finally, i checked my headphones. they were plugged in properly, and plugging them out and back in again didn't do anything either.
so i'm out of ideas what i could still try. sound hardware is realtek hd onboard sound, which is identified as "hda ati sb alc889a analog". kde is 4.4 rc3, which i've been using already since over a week without problems, so i doubt that's the problem.
I'm trying to copy folders from one ubuntu machine to another. Both have ssh and openssh-server installed and have worked in the past.ing "scp -r Pictures username@192.168.1.1:/home/username" after entering the remote password, I get a bunch of lines.
A couple days ago I booted up my Ubuntu 10.10 machine as usual,but the wired LAN connection did not work; it doesn't seem to see any wired connection devices. I can still connect to a wireless network with no problem, and if I plug that same ethernetable into another machine it works fine. I've been happily using this setup for weeks; the LAN only stopped working a day or two ago. So I figure there's two possibilities:A recent update caused NetworkManager to stop working with wired LAN connections, but I'm e only persothed affected (unlikely)My motherboard's ethernet port died (this motherboard only a couple weeks old, so this also seems unlikely)I'm not good at diagnosing problems with networking, so who can tell me where to st
I've been running Ubuntu 10.10 (Maverick) x64 quite happily on my Dell e6500 for the past few months until today when I woke the computer up from sleep mode and could not use the wireless. The network-manager applet simply has 'Wireless' greyed out. I tried rebooting, thinking it was an issue with the wireless card not re-powering on properly after sleep, but to no avail. how to begin here?
I have no idea what happened. When I restarted my laptop a message telling me that my hardware cannot support Unity came up. This is quite impossible, because I've been running Unity with no problems since 11.04 was released.
Compiz says that the interface is unity, and when I checked in login screen, it's not set to Ubuntu Classic or anything, just Ubuntu.
I have an asus EEE 1015N. Everything worked fine yesterday. I packed my computer, and went back home. After turning it back on, not only it didn't connect to the wifi network, but it did not even detect it. I know it's not broken or anything like that because when I boot into windows it works fine.I've been trying every solutionven in the "sudden wifi problems" threads in the forum (including checking the wifi power button, and trying to manually assign an access point to it), but to no avail.
My skype has suddenly stopped working. It starts then stops halfway though the startup. If i run it from the terminal it say Aborted as it stops. I've triedupdating the whole system, including enabling thee and backports options in software sources. I've tried re-installing skype, I've even re-installed the whole system.
I've started to set up a server at my house, where I eventually want to run it headless, and I can just VNC in from my other Desktop. I installed Ubuntu 10.10, setup remote desktop on the server, and from there was able to do any work remotely. That was nice. I turn the computer off at night, and the next day when I was going to work on it, I cannot VNC in anymore. One day passed, and now every time I try to use VNC it comes up with "Failed to connect to server" I also set a static IP address on the server too, so I know the address isn't changing every so often.
I am a proud user of ubuntu and basically this is my desktop: I have got rid of the bottom gnome taskbar and replaced it with cairo-dock and the top toolbar is only showing one pixel with a delay scroll down so when i hover by it it doesnt keep popping down unless i leave the mouse there. anyway thats besides the point. i use cairo-dock and have done for over 4 months. then all of a sudden it stopped working. I don't have a clue why, perhaps you have encountered this problem and know of a solution. im using 9.04 jaunty and latest cairo-dock. when i type cairo-dock -c into terminal i get:
I am running Karmic on a Compaq Presario V3000 and this morning my wireless card is not being detected by Ubuntu's NetworkManager. I have no idea what caused this... literally, it was working when I shutdown my laptop last night. When I right-click the NetworkManager icon in the panel it does not show "Enable Wireless" (only "Enable Networking"). When I run ifconfig in terminal it shows my wireless card as being there (UP Broadcast Multicast). One weird thing - on the front of the laptop there is an LED which lights up blue when the card is working (ie normally), but right now it is orange (ie, if you flick the switch on the front of the laptop to toggle the wifi on or off... I have toggled it back and forth but nothing changes!)
Version: Ubuntu 10.04 Relavant hardware: P5QL Pro built-in ethernet, cable modem with linksys wireless-G router (although problem is with ethernet connection, not wireless)
One minute my ethernet was working, and the next it stopped working. The only thing that I did between it working and not working was install electricsheep from Synaptic and then I shut down the computer. When I restarted a bit later, no ethernet connection shows up.
I checked the cables, made sure they are in tight.
My laptop connects using the same ethernet cable fine. So its not the cable or the router.
I reset the router and the computer at the same time. Still doesn't work.
I don't know where to even start with troubleshooting this sort of problem. Everything to the extent of my computer knowledge seems to be working fine.
I can't get any sound from either online audio or from a CD in drive. I've watched videos with sound with only occasional problems until today. I have been using MPlayer with internal audio 1 output - analog stereo output. When I start a vid, it will begin to D/L and play, but without sound. When I try to check the volume level everything pauses and then my system freezes. Sometimes it will release in a few seconds, but mostly it won't allow me to close Firefox and if I try to close the tab or window or Firefox, I have to reboot. Sometimes the vid will D/L without a problem, but no audio on playback. Oddly, when I bring up the system monitor, processors will show 1 or 2 cores stuck at 100% while the others fluctuate wildly. Download speed falls to almost nothing with occasional blips or nothing. I checked several sites and they all have the same problem. I have checked my physical connections, and bios settings.
There is an option for a RS780 Azalia controller 1 output Digital Stereo (HDMI) output, but I have not been able to make it work since the system was new. I don't know why.
This is the most recent SYSLOG file. The pulse audio errors have always been there, but since it didn't seem to affect playback, I didn't run it down.

My PS2 keyboard randomly stops working. Sometimes instead of this it get stuck on a letter/number (for example, it starts writing "aaaaaaaaaaaaaaaaaaaaa" non stop) and it stays that way until i reboot my computer. Even the leds (num lock, caps lock, scroll lock) stop responding. Yes, i have tried to unplug and plug in the keyboard but nothing really happens.
I have been using ubuntu troublefree for some month, but yesterday, suddenly the wireless internet connection stopped working. It happened after i used the turn off wireless network shortcut, now i cant turn it on again (usually this works fine).The situation is now, that when i click on the tray icon showing connection it says, wired network disconnected (it never said this before), then if i click on the wireless shortcut it also says wireless disconnected... But if i click again it doesnt show connections, the disconnected sign just disappears...?
I have recently noticed that my keyboard shortcuts stopped working.Things like F2 to rename files/folders, I think its ALT+F1 to bring up applications menu, however it comes up with a dialog saying Power Information. I also can not use backspace in FF to go back a page and things like that, which I find very annoying because I prefer to navigate with the keyboard and that deal.Yes I have Compiz installed however I have for a few months now without this problem which appeared only within the last fw days. I have had k at the keyboard shortcuts in Compiz and set them to default but nothing changed
I'm running a gateway lapbook w/10.04 LTS and an etheros wirless card. Card has been working fine for almost a year - from cold boot, warm boot, and recovery from standy (shut lid, open, press power button). I was fiddling with setting a static IP for the wirelss card by modifying the interfaces text file. I made some changes, and restored the file to its original contents after some noodling around. Wireless still worked fine after that. Last night I took the laptop out of suspend as usual - lifted lid, pressed power button - but the wireless indicator remained grayed out and I haven't been able to reenable wireless connectivity since. ifconfig shows the wireless card is there, and cabling the e-net port directly to my hub works fine.
