Ubuntu Multimedia :: Audio Suddenly Stopped Working?
Oct 24, 2010
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.

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 bought a Dell Inspiron with pre-installed ubuntu. All has been working for the last year and recently my integrated webcam stopped working. I was trying to use it on skype and it did nothing, although the program recognises I have a webcam, I tried cheese and the power light on my webcam comes on but again the screen does nothing.

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.

I have been using Skype 2.2 beta on Ubuntu 11.04 using a Logitech 260 camera/microphone -- all with excellent results -- for the past couple of weeks.Today, for some reason unknown to me, my Skype contacts began telling me that my audio was nearly unintelligible, though I had no problem hearing them. I initially thought the problem was at their end; but then I did a test call and listened to the play-back of my own voice recording, and it was awful. It's sounds like I'm speaking under water with a buzzing sound in the background, and the words are barely audible.I wish somebody could tell me what's going on. I do not recall changing anything on my sound system. I wonder whether the problem is with Skype or Ubuntu 11.04 or my own machine (which is brand new

I tried upgrading from Jaunty to Karmic, which borked booting on that partition. I made a fresh install of Karmic on another partition which is booting fine, but I can't get Audio CDs to work, period. They worked in Jaunty and every release before that I had installed. Data CDs work fine in Karmic. I'm using plain ol' Ubuntu 32bit. I'm not sure where to start. There have been other threads where other people had identical symptoms. Either the problem went away mysteriously on its own, or they gave up because nobody believed them. In any case, I'm beginning to wish I had stuck with Jaunty.

ok, everything worked fine after a fresh 10.04 install, and after some days now i suddenly got several disconnects from the wifi somehow (all other devices in house does not get disconnected, so its a local issue), tried to restart networking, and when i reboot, it works for some hours, then cuts of again. but, after the latest reboot, the sound card is "gone" i suddenly have no sound and a wifi that disconnects at will 13:24 everything worked 110% in all previous ubuntu versions

Been using openSUSE 11.4 64-bit for a couple of months now, things seem to run very smoothly, and I'm very pleased with it. But sometimes things just seem to stop working as intended although this probably have nothing to do with openSUSE and is most likely a bug in Banshee.Well, the title says all about the problem really, and it's not a big issue since I most certainly can use another program to rip my cds.

My Compaq Presario F739WM laptop has a Connexant HD Audio/NVidia MCP51 (reported by lspci) sound card.Ubuntu has always supported the card with no problem except the random popping noise but then I found a work around for that.Now for some reason, when I first turn on my computer and at login screen I can hear Ubuntu noises, yet seems once I login, no more sound or sometimes the successfully logged in sound.
The only changes that I have since the sound worked, was I installed pulseaudio but that caused no problems with that. The other change was a few kernel upgrades and other packages through normal update manager.I have checked that snd_hda_intel driver was loaded in the kernel and in alsa, all seems well.Pulse detects audio output in it's meter.I also tested the sound card to make sure it wasn't bad, in Windows 7 (dual boot) and it wokrs perfectly.

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.

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 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.

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'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'm using Ubuntu 10.04. I was happily connected to internet and surfing some forum, when wireless connection suddenly stopped working.
Now I can't find any access point, and I'm pretty sure I didn't do anything to justify this behaviour.
It already happened a month ago, but I had to format my drive, so I didn't really bother to try to solve the problem.
Anyway. I'm posting here the results of the commands I think I can help with a diagnosis; if something else is needed.
I'm using a different computer to post this thread, so I'm manually writing the output.
Code:
sudo iwconfig wlan0
wlan 0 IEEE 802.11bg ESSID: off/any
Mode:Managed Access Point: Not-Associated Tx-Power=20 dBm
Retry long limit:7 RTS thr:off Fragment thr:off
Encryption key:off
Power Management:off
sudo iwlist wlan0 scan
wlan0 No scan results

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 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.

Earlier in natty this was working completely. It's only just started happening about a week ago. I don't know what changed, all I know is it suddenly stopped working. Basically the bar at the top is still there but there is black underneath. I can put windows there but I cannot see them (Just black). If I click on an indicator it looks on the bar as if it is being clicked but I cannot see the menu. I have attached a screenshot.

I use a small application called bendometer.jnlp. On my desktop running 10.04 it runs fine after opening with "OpenJDK Java 6 Web Start".
I have installed the same application on my brand new laptop running Ubuntu 11.04 and it was running perfectly until yesterday. Yesterday it hung during the startup and since I killed the hung process it has refused to start again. If I now run it in a terminal using the command
Code:

Recently I had made some udev rules to communicate with a few devices using USB ports. For some odd reason, they suddenly stopped working. Here are my rules:
Code:
ATTRS{idVendor}=="0403", ATTRS{idProduct}=="6001", SYMLINK="HCS12"
ATTRS{idVendor}=="067b", ATTRS{idProduct}=="2303", SYMLINK="Driver12"
ATTRS{idVendor}=="050d", ATTRS{idProduct}=="0109", SYMLINK="Driver34"
According to the documentation, all that is needed to write proper rules is one match operator (relevant info) and one assignment operator (name of port). I am running kernel 2.6.31-22, so udev rules are valid for use (they require at least 2.6.15). My only guess is to include something that identifies the serial port.

Recently my wireless stopped working on my Debian testing system. It just doesn't connect. The best I get (only after a reboot) is that it says it did connect, but failed to get IP address. But usually it just tries to connect, disconnects straight away, connects again etc. so it never manages to associate correctly.
I am sure it did work about a month ago, stopped working after recent upgrades from the repository.

I installed Ubuntu 10.4 side by side with my Vista. This is on a PC I leave on permanently and use as a sort of Sever, so Security and Network connection are VERY important on this device. I use it for documents and IP PBX (telephone system). I currently use Vista and 3CX, but I plan to roll it over to Unbuntu full time once its up and runnng correctly - I will just need to change the Grub2 conf priority. After install, all was fine and I managed to make many changes to settings, apps and updates, but I have noticed in the past week when going in to make further changes the network has suddenly stopped working! According to Network Manager and the icon on the panel it is connected and I can not see anything obvious that is not correct. I tried doing a PING (192.168.1.1) from Network Manager to the main router, but it failed. I know that there is nothing wrong with the network nor the card or PC it all sits on. It's working now with Vista and my other machines. It must be a config some-where.

After several days of searching, reading and re-installing, I'm at a complete loss as to why autofs has suddenly stopped working.
Basically, I can see the shared folders on the host computer but as soon as I try to cd into the folders I get "-bash: cd: [directory]: No such file or directory" (where [directory] = shared drive.
The setup used to work and the exact same setup on another computer computer works flawlessly.
I'm running Ubuntu 11.04
Here is the content of auto.cifs:
Code:
Here is the content of auto.master
Code:
And credentials are stored in /etc/auto.smb.goblin (where goblin = name of windows computer sharing folders.
When I do "ls -l /home/shoryuken/TerraDrive/goblin" I get:
Code:
Now if I try to "cd" into any of the shared drives (like D-Drive, GW_Share or TerraDrive) I get the following:
Code:
A second or subsequent attempt at "ls -l" results in:
Code:
Note the question marks that are now everywhere.
I'm not sure where to look to find out why this is failing. The shared drive are visible, but then disappear when I try to access them. The same exact setup, on another machine works perfectly fine.
