Loud pop at shutdown.

Hello all,

I have this problem with all distro's out there, namely a loud popping noise coming out of my speakers upon shutdown, reboot and suspend. I did find a fix for this, as found here:
https://bbs.archlinux.org/viewtopic.php?pid=811795

This did in fact fix my issue for quite a while, but lately I have this popping noise again! As I don't want to blow my speakers up I now run modprobe -r snd-hda-intel manually before shutdown, reboot or suspend, but I'd like to have a permanent fix for this.

Can you help me with this? Thanks in advance. (If you need any specs or whatsoever, tell me. I do not know which logs/specs etc are relevant here)

I think you have to disable the soundcard powersave option.
Try smth like:

options snd_hda_intel power_save=0

in your /etc/modprobe.d/modprobe.conf.

Re: Loud pop at shutdown.

Try this:

open /etc/conf.d/alsa with your favorite text editor.

# Whether to mute the master volume when stopped ("yes" or "no").
# Useful for bad audio cards which make a noise on system poweroff.
MUTE_VOLUME="no"

just change that to yes, reboot and see if it helps

oh, and by the way

# Enables powersaving mode for AC97 and hda_intel audio chips.
# Set to 1 to enable powersaving.
# Set to 0 to disable powersaving (default).
POWERSAVE=0

power save is off by default...

Re: Loud pop at shutdown.

any other solutions?

i've tried both:

options snd_hda_intel power_save=0

and

# Whether to mute the master volume when stopped ("yes" or "no").
# Useful for bad audio cards which make a noise on system poweroff.
MUTE_VOLUME="yes"

but neither works. also, i tried to unload snd-hda-intel, but i get the error:

FATAL: Module snd_hda_intel is in use.

Re: Loud pop at shutdown.

It's supposed to be "MUTE_VOLUME="yes" for you, I said that above...

Re: Loud pop at shutdown.

Changing MUTE_VOLUME="no" to yes doesn't work. Anti-Desin, you have to kill all running applications that use sound (music players/mpd for example) before removing the module.

Any other options?

i actually used 'yes' on my system. when i copied the code from your post to add to my post, i forgot to change it. edited my post.

unia, i closed all sound applications, as far as i know.
