seem Jack detection problem do your front audio panel compliant to hda front audio specifcation ?
http://git.kernel.org/cgit/linux/kernel/git/tiwai/sound.git/tree/Documentation/sound/alsa /HD-Audio.txt Hint Strings ~~~~~~~~~~~~ The codec parser have several switches and adjustment knobs for matching better with the actual codec or device behavior. Many of them can be adjusted dynamically via "hints" strings as mentioned in the section above. For example, by passing `jack_detect = no` string via sysfs or a patch file, you can disable the jack detection, thus the codec parser will skip the features like auto-mute or mic auto-switch. As a boolean value, either `yes`, `no`, `true`, `false`, `1` or `0` can be passed. The generic parser supports the following hints: - trigger_sense (bool): indicates that the jack detection needs the explicit call of AC_VERB_SET_PIN_SENSE verb try hint trigger sense = false or disable auto mute ug 18 23:27:23 Ubuntu-Desktop-Corsair pulseaudio[3421]: ( 12.656| 0.001) [pulseaudio] module-alsa-card.c: Jack 'Front Headphone Jack' is now unplugged Aug 18 23:27:23 Ubuntu-Desktop-Corsair pulseaudio[3421]: ( 12.656| 0.000) [pulseaudio] device-port.c: Setting port analog-output-headphones to status no Aug 18 23:27:23 Ubuntu-Desktop-Corsair pulseaudio[3421]: ( 12.656| 0.000) [pulseaudio] module-switch-on-port-available.c: finding port analog-output-headphones Aug 18 23:27:23 Ubuntu-Desktop-Corsair pulseaudio[3421]: ( 12.656| 0.000) [alsa-sink-ALC892 Analog] alsa-mixer.c: Activating path analog-output Aug 18 23:27:23 Ubuntu-Desktop-Corsair pulseaudio[3421]: ( 13.083| 0.402) [pulseaudio] module-alsa-card.c: Jack 'Front Headphone Jack' is now plugged in Aug 18 23:27:23 Ubuntu-Desktop-Corsair pulseaudio[3421]: ( 13.083| 0.000) [pulseaudio] device-port.c: Setting port analog-output-headphones to status yes Aug 18 23:27:23 Ubuntu-Desktop-Corsair pulseaudio[3421]: ( 13.083| 0.000) [pulseaudio] module-switch-on-port-available.c: finding port analog-output-headphones Aug 18 23:27:23 Ubuntu-Desktop-Corsair pulseaudio[3421]: ( 13.083| 0.000) [alsa-sink-ALC892 Analog] alsa-mixer.c: Activating path analog-output-headphones Aug 18 23:27:23 Ubuntu-Desktop-Corsair pulseaudio[3421]: ( 13.104| 0.000) [pulseaudio] module-alsa-card.c: Jack 'Front Headphone Jack' is now unplugged Aug 18 23:27:23 Ubuntu-Desktop-Corsair pulseaudio[3421]: ( 13.104| 0.000) [pulseaudio] device-port.c: Setting port analog-output-headphones to status no Aug 18 23:27:23 Ubuntu-Desktop-Corsair pulseaudio[3421]: ( 13.104| 0.000) [pulseaudio] module-switch-on-port-available.c: finding port analog-output- -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1213769 Title: [ASUS P8Z68-V PRO, Realtek ALC892, Green Line Out, Rear] Popping sound or crackle every few seconds while playing audio To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1213769/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
