You will find below the hda info in my syslog :

are there any suspend and resume events of snd-hda-Intel occur in system
log ?

you better ask the author whether it is normal to have so many power

Thanks ! It works like a charm. No more automatic jack detection but all
the jacks are working properly and active simultaneously and the sound
is crystal clear. Much better than setting no presence with
hdajackrestask.
in /etc/modprobe.d just add a file hda-jack-detect.conf with the
By the way, you will find in attachment the hd-audio driver tracepoints
(I've enabled the trace.log while the bug occurs (randomly switch
between front output jack and rear output jack), then I've plugged an
headphone on the front jack a few seconds later : the erratic switch
disappears)

- jack_detect (bool): specify whether the jack detection is available
at all on this machine; default true
the alternate way is to specify hint by early patching for your analog
codec
I confirm : same issue on my brand new PC with Gigabyte Z87X-UD3H
motherboard...
Solved using hda-jack-retask to disable frontside input/output... not a
big deal but definitely not a solution !
Raymond :
1/ you should increase the status to confirmed ;-)
2/ How can I help you ? More information
you can use hdajackretask to set Misc bit (MISC=NO_PRESENCE)
bit 8 of pin default of your headphone and mic at ext front
so that driver don't use jack detection on these two pin complex
or
change pulseaudio conf
I expect the module-switch-on-port-available can stop switching when it
found that the states of jack are unstable (e.g. on and off more than 5
~ 10 times within a second)

Here is the log of pulseverbose.
I do not know how to enable the tracepoints of alsa doing echo 1
/sys/kernel/debug/tracing/events/hda/enable. Even using sudo the
terminal replies that I have not the permissions.
I disabled the AutoMute function with amixer.
The problem is still present.
Hi,
A person having the same issue as you actually had a hardware error -
the front HDA panel cable was not correctly connected to the
motherboard. So please first check that.

Hi David,
It's an integrated audio device. So I have not this kind of problems.
Then, on the outside, I check with three different kind of devices
(headphones, speakers (2)).

This motherboard has a front panel HDA connector, which is what I'm
talking about here.
If you left this connector unconnected, try disabling it in BIOS. If you
connected it to the chassis, check the connection.
