Crashing sound on startup of computer

Support Sound
1

In the left audio channel, I sometimes hear a crashing sound.

I remember, I had to reinstall Manjaro KDE with pipewire.

Does this come from pipewire or is the mainboard defective (sound chip) ?

I have swaped the two channels of the loudspeakers and now the sound comes from the right channel.
So the source of the sound is the computer.

I measured the booting process (Linux) with a digital voltmeter. I measured a peak of 4.5 mV.
I measured the booting process (Windows) with a digital voltmeter. I measured no peak.

“sometimes” is not a good start

What is (or may be) the significance of that?

It is the source in any case.

It depends on the type of “voltmeter” and how it aquires it’s measurements
and on the measurement process
whether this observed difference can even tell you anything.

The source of the sound could also be the loudspeakers.
But I swaped the two channel (left to right and right to left).
The sound the came from the right channel.
So, the cables and the loudspeakers is not the source.

I measured the peak in the left channel with digital voltmeter in 200mV DC range.
I can measure the peak on every boot process.

The sound of the two channels is the same and sounds good.

If the ‘crashing sound’ is audible only when system is booted it is more likely to be an issue with alsa/kernel. But if there is similar noise when starting or stopping audio playback or suspending/hibernating it is more likely to be from pipewire/wireplumber

If you are using kernel v6.7 or v6.8 I suggest you use an LTS kernel v6.6 or v6.1 as a temporary workaround - sometimes these noise issues are resolved by a kernel update

Disabling power management in ALSA may also help
sudo tee /etc/modprobe.d/hda-no-suspend.conf <<< 'options snd_hda_intel power_save=0'
