Overview
Sometimes you might hear a pop/click from the speakers, usually when audio starts/stops, or around suspend/shutdown.
This is typically caused by the audio amplifier powering down/up when the driver enables power saving. It’s not dangerous, but it can be annoying.
We have upstreamed a runtime adjustment to improve this, but while that change trickles down to different distributions, you can use the workaround below.
Affected devices
This can affect some Star Labs devices on Linux (for example Star Lite Mk II).
What you will do
You will:
- Create a small configuration file for the audio driver.
- Rebuild the initramfs (on some distributions).
- Reboot.
Step 1: Open a Terminal
Open the Terminal app.
Common shortcuts:
- On many distributions: press
Ctrl+Alt+T - Or open your app launcher and search for
Terminal
Step 2: Create the config file
Copy and paste this command into the Terminal, then press Enter:
sudo tee /etc/modprobe.d/sls-eapd.conf >/dev/null <<EOF
options snd_hda_intel power_save=0
EOF
Notes:
- You may be prompted for your password. When typing your password, you will not see any characters appear. This is normal.
- This change can slightly increase idle power usage (battery life).
Step 3: Rebuild initramfs (pick your distribution)
Some distributions bundle driver options into an initramfs (an early-boot image). Rebuilding it ensures the change is picked up.
Run the command that matches your distribution:
Ubuntu / Debian (and derivatives)
sudo update-initramfs -u
Fedora (and derivatives)
sudo dracut -f
Arch / Manjaro
sudo mkinitcpio -P
Step 4: Reboot
Reboot your system. The change takes effect after reboot.
sudo reboot
Verify (optional)
After reboot, you can check the setting with:
cat /sys/module/snd_hda_intel/parameters/power_save
It should output 0.
Undo (revert the change)
- Remove the config file:
sudo rm -f /etc/modprobe.d/sls-eapd.conf
- Rebuild initramfs again (same command as in Step 3 for your distribution).
- Reboot.
