Cracking sound in speakers

Hi, I need urgent help to fix the problem of the sound from speakers. The sound is OK in the headphones but cracking in the speakers of the laptop.
I tried to edit /etc/pulse/daemon.conf by setting "default-sample-rate = 48000". It didn't help
I tried to edit /etc/pulse/default.pa be setting "load-module module-udev-detect tsched=0". It didn't help
I recorded the sound and put it here

The laptop i use is HP Pavilion g6

$ aplay -l

Please, help me to restore sound. It worked recently. But, probably after forced shutdown it started to work like this.
I can provide all relevant info.

Re: Cracking sound in speakers

your volume is at 141% there are speakers that will start to crack with that high of an overdrive, tune that down to something sensible

Re: Cracking sound in speakers

This may not be the case for you but I do know that my own laptop speakers really can't handle exceeding 100% volume. They'll start buzzing and cracking when I go beyond 100%.
Your speakers seem to be set to 141% at the moment. Try to set them to 100% instead.

EDIT: Posted at the same time as V1del...

Re: Cracking sound in speakers

I changed to 50% - the same crackling.

Re: Cracking sound in speakers

Don't bump your thread.

You may have damaged your speakers, if that's the case then no amount of software configuration will make it better. If you have the possibility try with windows and see if the same thing happens.

Re: Cracking sound in speakers

What are you using to test? can you post

pacmd list-sink-inputs

during your tests? do you get any output from affected programs relating to ALSA under-/overruns? Anything in dmesg related to the soundcard? You could try removing ~/.config/pulse and running

sudo alsactl init

to reset the soundcard, I don't think it's gonna help much though
