Ubuntu :: WIFI And Sound Loss After Kernel Update In Hardy
Jun 9, 2010
I have a Hardy which last night asked for updates that included kernel changes. Today I find I no longer can connect using WIFI and have no sound. The GUIs are just not there and it's as if the controllers themselves have disappeared. For example lshw -C network reveals a Cisco Airon Wireless, but it's not listed as a wireless device, just as network controller.Can anyone advice me on how to approach this? Is it possible to revert changes or something?

I just lost the sound to Xine after updating Hardy. It works fine otherwise and I have sound with Totem and VLC so it would seem to be a Xine-only problem.

I just installed 9.10 Karmic Koala and everything was kosher. I installed Amarok and the libxine plugins etc and was getting sound and able to play my mp3s, I let the update manager run and voila now without any sound. Machine is a gateway desktop using Realtek High Definition Audio.

I've installed opensuse 11.3 few days ago on my laptop, and it seems after kernel update, wifi refuses to work. I'm using gnome and after the update the iwlagn module was not present in the 'ifup'. So i run modprobe iwlagn and here is the output.

I just upgraded (included kernel updates) using the normal update manager on my wife's Dell 1420 Inspiron Ubuntu 8.04.4 LTS with security, proposed and backports. After the upgrade reboot the sound and wifi were broken--- the system reported there was no hardware. I suspect this is simply a bug with the new kernel. A couple years ago a similar bug to the sound driver forced us to skip a kernel. I suppose I should file a bug report about this somewhere?
It is simple enough to boot into the previous kernel where sound/wifi do function, for now. However I'm also getting a strange dependency problem for the packages linux-generic linux-image-generic linux-restricted-modules-generic These packages "have been kept back" according to aptitude. They are stuck at 2.6.24.28.30. I'm unable to force install them to the newer 2.6.24.29.31 to match the other latest installed packages and the latest kernel listed on the GRUB menu. I wonder if the reason the sound and wifi are broken is that these won't update.
If I try to update the aptitude dialogue gives me solutions with +259 to remove the linux-generic package. But isn't that an important package that I need? Why is it suggesting I remove these? Maybe they are obsolete meta-packages? I can't get it to install 2.6.24.29 no matter what I do. I removed and then installed these packages and none of that get the sound working. To remove and install I had to run aptitude and it would give me solutions saying -29000 but I did it anyway to try and force it. None of it worked so I just put it back to the way it was, with the "held back" 2.6.24.28. I don't really understand package dependency.

After i updated to the kernel version 2.6.34.7-61.fc13.x86_64 my wireless stopped working!
My network card is a Broadcom Corporation BCM4311 802.11b/g WLAN (rev 02)
The interface is not listet anymore under ifconfig, under the network icon i see only wired networks.
If i boot using the old kernel (2.6.34.7-56.fc13.x86_64) everything is fine.
when i run lshw -C network i can see that the driver is not loaded correctly
Code:
*-network UNCLAIMED

Squeeze's latest update has upgraded my kernel from 2.6.32-3-686 to 2.6.32-5-686.My wireless stopped working and then I realised that I had to rebuild the wifi modules. I had followed this earlier.URL...For this new kernel, which I step of the process should I repeat? Rebuild module? Or just do a modprobe?

I am running hardy on my laptop and was thinking its time I upgraded. One thing that's been holding me back is I have a number of wifi keys stored in there somewhere and can't remember what they were exactly. Are they exportable?

Today, I installed the recent kernel security update (i.e. 2.6.32-24-generic #41-Ubuntu SMP). After a reboot, the sound is gone.
From my user account:
mpc@awd:~$ alsamixer
cannot open mixer: No such file or directory
Same problem with "aumix".
However, the commands "sudo alsamixer" and "sudo aumix" seem to work (but still no sound).
"lsmod | grep snd" will give
snd_hda_codec_atihdmi 2367 1
snd_hda_codec_realtek 203310 1
snd_hda_intel 21941 0

The audio stopped working since I upgraded my kernel from 2.6.35.6-45 to 2.6.36.6-48.
Is reinstalling alsa / pulse the only option ?

Well, the gdm issue was pretty easy to solve. Just reinstalled NVIDIA video drivers in runlevel 3.
But sound seems to be a litle more dificult. Before I spend some hours, I would like to ask if some had the same problem.
By the way, here is my alsa-info.sh url.

I just updated my kernel from 2.6.32-21 to 2.6.32-22 today. Now I am getting no sound. I have checked my mixer levels with both kmix and alsamixer. Nothing appears to be amiss. I tried rebooting with the old kernel and still no sound.

The latest Kernel update (2.6.35-25-generic) killed all my sound output on my Toshiba Satellite M115.
I tried reinstalling all ALSA components and plugins. No luck there.
Rebooting into 2.6.35-24-generic fixes the problem, in that my sound works again.

After I upgraded from kernel 2.6.32-31 to 2.6.32-32 and then 2.6.32-33, my sound started to lag(the lag occurred on 2.6.32-32 and stayed to 2.6.32-33, but it worked perfectly ever before). Sound does work in itself, but frequently lags and pieces that were already played before will be played again, pretty much like an old vinyl that occasionally jumps or hangs. When I start to replay something, it does not put out anything for a second or two and then starts, when I stop it will keep playing for the exact same amount of time. So, sound is synced to videos(video replay works perfectly well and without the lag). Problem is definitely related to the sound drivers, not to replay software or any buggy file. It occurs with DVDs, Flash Videos in Firefox, music in gmusicbrowser, movie files with VLC, whatever you want. I never experienced such problems with any kernel before. Although I've seen many others posting similar problems, I cannot see any valid solution for myself.
I'm running Ubuntu 10.04 and I sure don't want to go to 10.10 for the second.
I reinstalled Alsa and Pulse, no joy. My sound card is recognized correctly by alsa and can be found in aplay -l. It's a generic onboard surround sound device, although I only use stereo channels.

Meanwhile I have upgraded to Ubuntu 10.10 Maverick Meerkat and sound over HDMI works there without any problems so far after unmuting all channels.

So I just finished doing a Hardy based LiveCD. I made an installation in VirtualBox, installed some packages, and then compiled a totally new kernel, 2.6.35, actually this one: [URL] I compiled squashfs support in the kernel naturally Everything seems to be fine, the system boots up normally etc. But here comes the trouble: I make the iso file with remasterys (2.0.12-latest for Hardy) but this iso isn't able to boot.
It drops to busybox shell, casper.log says: /init: 1 /dev/sr0: no such file or directory Unable to find medium with the livesystem. My /dev folder is totally empty, it contains only the shells (8 pieces of tty). I don't know what's wrong...my rootfs is surely mounted, mount shows rootfs rw /

I am experiencing sound problems after an upgrade to kernel 2.6.29.6-213.fc11.i686.PAE from kernel 2.6.29.5-191.fc11.i686.PAE in several games like Neverwinter Nights (linux binaries) and Warcraft III (PlayOnLinux). The sound stops and changes into a very choppy annoying sound. When I boot into the old kernel the problems are gone.

I use the on-board sound chip of a Gigabyte motherboard (Realtek)and I have connected it with optical cable to an amplifier.
Everything worked fine, until February, when an update changed the kernel and the PC stopped giving sound signal! When I returned to the previous kernel (at grub), again everything worked. So,it doesn't seem to be a connection or drivers problem.
I supposed that with 11.04 edition this problem would be solved. But it isn't. In fact I have serious problem now because the old kernel isn't listed in grub anymore.

I've had issues with the later versions of Ubuntu, so in an effort to road-test Firefox 3.5 on Hardy I'd like to change my Karmic/Hardy dual boot to a Hardy/Hardy dual boot, and follow the instructions in [URL] to put the Mozilla build of 3.5 on the new installation.
I can't see any reason why a Hardy/Hardy dual-boot shouldn't work, but does anyone know of any issues with this I might not be aware of?

I configured my Xubuntu laptop to work with my Netgear Wireless router to connect to the Internet. I was able to connect, and downloaded Hardy updates of 184 MB. After installation of the updates, the system prompted me to restart. The Wireless network is not working since then. Tried reconfiguring, but to no avail. The proprietary drivers for my wireless network card have been downloaded and installed... remember, it worked well enough download the updates! Posting this from my Windows partition using the same wireless network A previous thread [URL]...k+Hardy+update) with the same issue seems to have hit a roadblock...

just installed hardy after I removed Maverick since it doesn't support my ati graphics. I installed it inside my windows xp pro and run smoothly after installation, added couple of widgets and so on... after I restarted it the next time, a balloon showed on top saying 113 or so updates are available, so I updated it.
After update I reboot my lappy and it won't get to my ubuntu anymore but works fine with my xp. I tried several searches on the net to find the solution but can't really figure it out. I just tried running Boot info script as it might help experts figure out what's wrong with my box and here's what it shows:

Not sure this right place for this. After updating from Ubuntu 10.04 to 10.10 lost internet connection - was instantaneous loss. Wired connection computer to router. Icon on computer shows "wired connection 'auto Eth0'active" The router shows line connected ok. Computer shows connection is established. Connection information menu shows details such as IP address broadcast address and other details. Where do I go from here to reconnect to internet.

I'm having problems keeping audio working. Using Sparky with 3.16.0-4 kernel on a homebuilt PC. AMD A10-7850K CPU on a Gigabyte F2A88FN-WIFI mobo.
I'm using a set of Logitech Z-5 USB speakers and I repeatedly lose all audio output. To get it back I need to do 1 or all of these steps:
1) Unplug the speakers
2) Kill all processes that may be producing audio (Chrome beta, IceWeasel, Exaile, etc.)
3) Start Alsamixer and select another source in sound card list then reselect USB card #2.
4) The weird one - Remove and then re-add the volume applet that I like to have in the panel. When I lose sound th slider gets "stuck" and will not move. It will not recover.
I may need to repeat this several times but it will come back. Not immediately after any step but after a few attempts it just begins working as long as nothing is trying to produce audio at the moment. Sometimes Alsamixer says that my USB Card has no controls when I reselect it, not every time though.
Most of the time if I have more than 1 source open at any time it is likely to die again, for instance I like to stream Google Play Music. If I pause that but leave it open, then try to watch a Youtube video or other source I will either get no audio from either source, or lose the streaming audio source when I try to restart it. Going through the above routine 1 or more times usually restores it.
I have created asoundrc.conf file to tell system to use USB audio as described here -> [URL] ..... In my case USB is # 3 in the list. So this is my file:
Code: Select allpcm.!default {
type hw
card 2
}
ctl.!default {
type hw
card 2

Machine: Win2000 Pro, AMD64 Athlon 2GHz, 2x80Gb HD, 2 GB RAM Symptoms: Running 9.10 with dual boot no probs for ~ 1 year. Decided to upgrade online via synaptic to 10.04. Upgrade went well no warnings, etc. On reboot all OS options present in Grub BUT clicking on Win2000 causes the screen to blank temporarily and then return to the Grub menu ie. no functioning Win2000 boot option. Ubuntu 10.04 boot yields blank screen with flashing cursor, a sudden stream of IO error messages (can't capture it but the lines look identical) then screen flickers and I'm at the purple log in screen and everything proceeds perfectly from there.
Observations: For the first time on any of my ubuntu installs (i've been using since 8.04 always installing from CD though) grub installation asked where I wanted it. In fact, the screen shows all devices with check boxes wth which to make my choice. That is sdb, sdb1, sdb2, ... , sda, sda1, sda2, There was a message that says that if in doubt install on _all_. Being in doubt I checked all the boxes: sdb, sdb1, etc. I noted in the message streams that followed after i continued that some lines had "... this is BAD ..." but since it was all rolling along very quickly no idea exactly _what_ was bad.
Action: I am not a linux newb but I am a grub newb. I fished the forums and googled only to come completely confused about what the problem might be or what to do. Example: have i overwritten my win bootloader? is my mbr corrupted? if i remove grub what will happen? if i remove and reinstall grub will i get windows booting back? if i use my win2000 install CD will it overwrite my whole disk (as many warn) or can i just fix the mbr? if I do the latter what order do i ie use fix mbr then fix boot? The info i've come across so far either doesn't address what happened to me, deals with other OSs (XP, Vista), or is applied to earlier editions of grub/ubuntu. Right now I have not found a clear step by step that addresses my circumstance. Would anyone be able to provide some guidance? I need the windows boot to run some software (Matlab) that btw will not work with XP/Vista (hence the reason i still have win2k).
