Hello community, this is my first post and I not speak english hehe.
I was experiencing a problem on my Arch Linux system with PipeWire and SDDM. Every time I logged in, I heard a persistent white noise that only went away when I played an audio file or started pavucontrol. This problem occurred until I took some action to activate the sound. I use generic analog sound on speakers.
My system configuration:
Operating system: Arch Linux
Login Manager: SDDM
Window manager: Qtile
PipeWire: 1.2.6
Motherboard: B450M TUF gaming.
My solution is disable kernel level energy saving. (ALSA)
1st. Edit the audio module parameters.
Open or create the configuration file for ALSA
sudo nano /etc/modprobe.d/audio_power_save.conf (or any editor, nano, micro, etc)
2nd. Add this line:
options snd_hda_intel power_save=0
This disables the power saving feature of the snd_hda_intel module. its common.
3rd. Reload the module or reboot the system.
To reload the module or reboot:
sudo rmmod snd_hda_intel && sudo modprobe snd_hda_intel
