Hello all,
I'm having a weird issue with my sound or speakers. I have always had this popping noise on shutdown or reboot, but haven't been able to solve it. It turned out that the alsa modules aren't unloaded properly.
Now however, I'm not having this issue only upon shutdown or reboot, but every time there is going to be sound from the speakers or there was sound (e.g when I close YouTube / Rhythmbox / Emesene)
Seeing the popping noise is the same, I suspect it's the alsa modules again. However, I'm unsure and I don't know what to check for any errors. Also, I didn't know what exactly to search on, so forgive me if something along these lines has been posted already. If you need any info, please ask!
Thanks in advance.
PS: I think installing kernel26-lts might work, as I didn't have this issue before with Arch. (I just installed Arch again) I'd like to have a fix for this kernel though, so kernel26-lts is a backup option for now.

I should probably add that I don't have this issue everytime I boot. Sometimes it appears, but then upon reboot it doesn't anymore.
Also, when I have last closed an application which used sound and the speaker has popped, I don't have the popping noise on shutdown anymore. Thus, my guess is that the popping noise is from loading / unloading the alsa modules. How can I make sure the modules get loaded (succesfully) everytime I boot?
Might be of interest: I only installed alsa-utils and ran alsaconf to configure it.

This is probably caused by audio power management.
Run this:
cat /sys/module/*/parameters/power_save
If this command returns 1, then find that "power_save" file and set it to 0. This will disable power management; your audio chipset will be on all the time (bad), and will not "pop" anymore (I hope.)
Note that you'll have to add "echo 0 >/sys/module/<your chipset>/parameters/power_save" to your rc.local so that it's done at each boot.

It returns a 0

wget -O alsa-info.sh http://www.alsa-project.org/alsa-info.sh
bash alsa-info.sh --upload
Then show us the URL that the script shows at the end.
Also, use the ALSA bugzilla.

What do you mean with "use the ALSA bugzilla"?

Please dont bump threads unless you have something addtional to say about what you have tried.
There's no such thing as a stupid question, but there sure are a lot of inquisitive idiots !

did you mean "beep" ? if yes , please try to add pcspkr to module blacklist .

By that, I think you mean put '!pcspkr' in the module list.

Ǹo, it's not the system beep.
Though I haven't had the popping noise for the last couple of days, but I didn't change anything (no updates either)

Ok so I nailed down the issue as to what module it is related; it is in fact the snd_hda_intel module. I could just not load it, but if I don't I have no sound.
Do you think this is reason enough to file a bug report? If so, will the alsa-info script suffice for the required information?
EDIT: Nevermind, I found the issue! You have to edit /etc/conf.d/alsa and set the MUTE VOLUME to yes.
