Luke, please unassign and comment if you cannot address this

Derek, are you still seeing this problem with current karmic?

[mogwai (scruffy-mogwai)]

There is a work-around that seems to work for most people with the Intel HDA cards/chips:
Commenting "options snd-hda-intel power_save=10 power_save_controller=N" in /etc/modprobe.d/alsa-base.conf
Or see: http://www.youtube.com/watch?v=RSbw42MkPvE

PS: I am using Karmic 9.10 official release (Kernel: 2.6.31-14-generic #48-Ubuntu SMP Fri Oct 16 14:05:01 UTC 2009 x86_64)

Also, there seems to be a lot of duplicate bugs out there, most with Intel HDA cards/chipsets. Might be an idea to go through and mark as dups, perhaps?

I followed all the comments left here changing my alsa-base.conf file but nothing stops, the speakers from buzzing then popping on when something makes noise. I only ever have this sound is at reboot but all my computers have. Not when an operating system is on and active, (sleep mode causes that) but I guess it is a flow of power perhaps to the speakers that keeps them from buzzing (since it does it when they are unplugged from the computer).

So I tried changing the time to 30 or 900 that didn't change, I commented the line out but that didn't work.

System is Completely upto date with Ubuntu karmi x64 9.10
2.6.31-17-generic #54-Ubuntu SMP Thu Dec 10 17:01:44 UTC 2009 x86_64 GNU/Linux

BTW, the only thing that stops the buzz then pop thing is to stream music all the time and mute your system. But of course this is hardly a fix.

I was having a popping sound issue on the newest 9.10. I found a workaround post on the Ubuntu forums that seems to be working for me, but not for everyone. Here is that post: http://ubuntuforums.org/showthread.php?t=1312690 As per the instructions I'm to make a bug post, so instead of posting a duplicate issue I'm posting in this one. I was also instructed to post the contents of my codec file, so I've attached it below.

Thanks.

hello

 I have installed Kubuntu 9.10 and have had problem with sounds cracks on my HP pavilion dv6618eo with HD nVidia audio. but I fixed this by installing the following packages:

 1. gedit: the official text editor of Gnome.
 2. gksude: installed this through Terminal

 after installion,I then entered the following code in terminal:

 gksudo gedit /etc/modprobe.d/alsa-base.conf

 and then changed the following code in Alsa-config:

 options snd-hda-intel power_save=10 power_save_controller=N

 changed to:
 options snd-hda-intel power_save=0 power_save_controller=N

 after all restarted the pc, and all was successfull, and the cracking sound fixed.

 in ubuntu, no need to install gksudo and gedit. just open terminal and paste in the following code:

 sudo gedit /etc/modprobe.d/alsa-base.conf

 or
 gksudo gedit /etc/modprobe.d/alsa-base.conf

 then change the power save from 10 to 0.
 and restart pc.

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 395208

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.
