Speaker creaks on Dell Latitude E6400

Please un-assign and comment if you can't address this.

it is still in beta

I have LenovoR61(Ubuntu Karmic) and i noticed the same bug. Help guys :((((

I think it's some kind of power saving mechanism. I have found a notice on an archlinux wiki page about alsa where It says, that you should try to load the "snd-hda-intel" module with the option "power_save=0" by directly loading it from the commandline or by adding "options snd-hda-intel power_save=0" to the modprobe.conf file.

I couldn't test it on my machine because I have no version of Karmic installed right now, but maybe someone could give it a try.

Source: http://wiki.archlinux.org/index.php/ALSA#Pops_when_Starting_and_Stopping_Playback.3F

On my Dell Latitude E6400, when i make the change of the option in modprobe
like this : "options snd-hda-intel power_save=0", the sound is working once with the
first screen of gdm, but after i have no sound when il log in.
unfortunately, it was another parameter of the option regardind power_mgr wich was on NO
but i can't remember the exact option name.

Finally, i have commented out the line for # "options snd-hda-intel power_save=0" and nox the sound
is working pretty well.

OUPS, i forgot to say that i am on ubuntu Karmic beta with the latest updates as of 19/10/09

Thanks and keep on the good work

Same as Andrelo :

In etc/modprobe.d/alsa-base.conf you just have to comment #options snd-hda-intel power_save=10 to solve the problem.

I have asked on ubuntu forums and it seems that a lot of people have that problem.
No idea what impact ther is to disable the power save function.

speakers are creaking because two programs r accessing them. this fixed that problem for me.

almost willing to bet fix all sound issues in karmic, unless hardware completely doesnt support it, like SIS graphics

software conflict, this should fix it

since this is a microsoft, i mean software conflict problem, you should be able to use this method on all karmic install no matter what your hardware is. if not, i would suggest backing up your info and starting from the top. again tho, you shouldnt have to. any pakages you already have shouldnt affect the script either, or your install. restores all sound including system sounds. also stops freezing issues that happened when adjusting audio settings.

THIS METHOD CLEARS OUT PULSE COMPLETELY BUT DOES FIX THE SOUND. I TESTED THE SCRIPT ON A FRESH INSTALL EVERYTHING WORKS PERFECT AFTER SUDO NAUTILUS. KEEP READING

sudo apt-get remove libsdl1.2debian-alsa

includes audacious music player, vlc , and ubuntu restricted extras(minus pulse updates :D ).

@all: please be careful if you are considering following the instructions in the previous comment. These actions are not supported, and *may* result in a broken system.

This bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? Can you try with the latest development release of Ubuntu? ISO CD images are available from http://cdimage.ubuntu.com/releases/ .

If it remains an issue, could you run the following command from a Terminal (Applications->Accessories->Terminal). It will automatically gather and attach updated debug information to this report.

apport-collect -p alsa-base 418646

Also, if you could test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text. Please let us know your results.

Thanks in advance.
