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 following lines : # This file was added as a workaround to the jack detection issue with a Gigabyte GA-Z87X-UD3H motherboard # If you want to revert the changes, you can simply erase this file and reboot your computer. options snd-hda-intel patch=hda-jack-detect.fw And in /lib/firmware add a file hda-jack-detect.fw with the following lines : [codec] 0x10ec0899 0x1458a002 2 [hint] jack_detect = no Then reboot ! For information : you can check the file /proc/asound/card0/codec* to verify that the [codec] line matches your hardware (vendor-id subsystem-id address) head -n 10 /proc/asound/card0/codec* Codec: Realtek ALC898 Address: 2 AFG Function Id: 0x1 (unsol 1) Vendor Id: 0x10ec0899 Subsystem Id: 0x1458a002 -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to pulseaudio in Ubuntu. https://bugs.launchpad.net/bugs/1248116 Title: PulseAudio switch rapidly port making the sound horrible Status in “pulseaudio” package in Ubuntu: Incomplete Bug description: I have a Realtek sound system integrated to the motherboard Gygabyte Z87X-UD3H (http://www.gigabyte.fr/products/product- page.aspx?pid=4481#sp) having problems on Ubuntu 13.10.
