Should now output 1 and this should give you the sound problems this bug was originally about again. Sudo rpm -ivh kernel-core-4.15.86_64.rpm kernel-modules-4.15.86_64.rpmĬat /sys/module/snd_hda_intel/parameters/power_save
The plan is to use a blacklist for devices on which this causes issues and I need your help to populate this blacklist, getting your device on this list know means that things will just work when you upgrade to F28 later.įirst of all to test this I need you to (temporarily) switch to running a Fedora 28 kernel, download these 2 files: But for F28 we are going to turn this on by default as it results in a significant power-saving. So this bug has been closed because this is fixed by disabling the codec autosuspend for F26 and F27. It looks like power saving simply disable the sound device which will always cause an problem like this if the sound system isn't power off too. In other words a noise because of a missing input source. It's the same noise if you unplug a electric guitar from an amplifier if you forgot to power off the amplifier first. Well it's normal that i hear a noise in my speakers if i start the system from grub2 until kernel finishing sound setup.īut with 'power-saving active' the noise come back with further booting and in X session.
My board is a asus P5Q_Deluxe (not very new :-)) and i use a 5.1 loudspeaker system from logitec.
