I see the same behaviour, but it does not annoy me enough to disable it. Yes, it is caused by a audio chip power saving mode which was enabled by default on Fedora 28. This happens quite often, especially on badly designed computer mainboards.
Implementation tracking bug: https://bugzilla.redhat.com/show_bug....
In case you are using an intel chip, the temporary solution to disable power saving is running echo 0 > /sys/module/snd_hda_intel/parameters/power_save
. Creating the file /etc/modprobe.d/audio_disable_powersave.conf
with this line options snd_hda_intel power_save=0
should disable power saving on your sound chip permanently after the next reboot, you may need to regenerate your initramfs using dracut though.
If your device has no intel driver, please have a look at the kernel module. You need to list your kernel modules first using lsmod
, then find your vendor's name in some of the snd_hda_
names. Documentation on that kernel module may help you get the right options.
same here on 2 MACs running Fedora28. The popping sound is also at the login prompt
This solution might be what you're looking for -> My speakers (headphones) pop out before sound :)
