Loud Pop on Laptop Speakers When Rebooting

Ask Fedora

1

Two loud asynchronous pops around 0.5 seconds apart in my right and left laptop speakers consistently happen upon running any reboot (systemctl reboot or reboot). They happen after the screen is shut down, just before the power indicator turns on again.

I am running Fedora Sericea 38 (Silverblue, but using Sway), with an Intel Raptor Lake card (probably virtual?) that manages my laptop’s speaker and a headphone jack. There is also a disabled Nvidia audio device.

The issue does not occur when powering off then back on. When my external headphones have been unplugged for a sufficient time before rebooting, the noise does not occur.

The pop does not occur the restart after modifying modprobe.d, as it seems that the reboot sequence after this modification is different.

I have disabled power save using /etc/modprobe.d to no effect. I have also disabled the “pc speaker (beeper)” to no effect.

When you said the nvidia audio is disabled are you saying the GPU is disabled or that only the audio side is disabled/unused.

Please post the output of inxi -Fzxx to provide more info.

I’ve shared the results of the command above in the post. I believe it’s the audio side that is disabled: the GPU is still running normally.

You have what appears to be a very new GPU and no driver loaded, not even nouveau.
I would first suggest that you install the nvidia drivers from rpmfusion and see if that makes a difference. Having a device capable of audio output but not having the driver for that device loaded can have unintended or undefined consequences.

The gpu with no driver causes the CPU to be tasked with excessive load in rendering graphics that would normally be managed by the hardware acceleration of the GPU which can also interfere with audio as well as everything else the machine normally does.

I have went through a long process and installed the Nvidia proprietary drivers. However, the issue persists.

Hey,

I also have a Thinkpad P1 Gen 6. Unfortunately, I can confirm that this issue is caused by the machine’s firmware and is not a Fedora issue.

I’ve reported this issue to Lenovo, but I’m afraid it’s not going to be an easy fix on their side.

I have a Legion Pro 7 16ARX8H running Fedora 40 and also experiencing this issue. Not sure what’s going on.
