[SOLVED]Speaker Pops?

On Linux, my speakers love to pop for some reason, and it's really annoying. Not only do they pop, but they make white noise.

If you need any other commands, just let me know

*EDIT: If it matters, TLP is installed (but it happens usually when audio is not playing, regardless of if it is plugged in or not.)

When posting configs, code or command output, please use [ code ] tags, not [ quote ] tags https://bbs.archlinux.org/help.php#bbcode

like this

It makes the code more readable and - in case of longer listings - more convenient to scroll through.

This is quite common issue with some audio chips when audio power saving is enabled. Only way to resolve this seems to be disabling audio power saving, which is bit of a drag if you have a laptop.

I see you already have disabled it via modprobe.conf, but you probably need to disable it for TLP also. you can do this by adding SOUND_POWER_SAVE=0 in /etc/default/tlp

@ooo, from the posted /etc/modprobe.d file in the first post though, it would seem that this is a desktop/server and that the snd_hda_intel power_save it turned off...

ooo, if you have any tips, please add them to https://wiki.archlinux.org/index.php/Al … g_playback , but OP is already doing what's in there.

It seems like the TLP fixed it. I haven't heard the issue again so far. If it does, I'll be back! haha

@WonderWoofy,@karol, sorry I made my previous reply a bit hasty, so the point may not have come out very clear.

What I think is going on, is that even though you have disabled audio power saving via modprobe.conf, when TLP runs (after modprobe), it enables audio power saving again by its default configuration.
you can test this by checking /sys/module/snd_hda_intel/parameters/power_save after enabling audio power saving for, and restarting TLP

I don't know if that is worth adding to the wiki, since this is sort of a special case, and if people are using scripts like TLP they should already understand what it is doing.

happy to hear that my suggestion seemed to fix your issue :)
