Bug 71766

post the pulseaudio verbose log when you plugged the headphone

do your computer chassis have hda front audio panel or AC97 audio panel ?


/sys/class/sound/hwC0D2/driver_pin_configs:
0x1c 0x993301f0


the driver may need to differentiate alc889 and alc898 when apply CD fixup since you motherboard have same pci ssid 

SND_PCI_QUIRK(0x1458, 0xa002, "Gigabyte EP45-DS3", ALC889_FIXUP_CD),




[    5.665166] snd_hda_intel: unknown parameter 'indep_hp' ignored


do you think the driver should enable independent HP for those motherboard with 10 channels DAC and four line out jacks by default ?

The log can be found here: http://www.hamich.net/files/pulseverbose_linux.log

Some more observations:

-using the front audio port with my headphone, every 5 seconds a burst is coming out of my green-audio-port at the back. The burst seems to be a very short part of the audio stream playback.

- under FreeBSD the front-panel does not work at all. That could be the reason the sound works perfect there, out of the green-port.

Both options are possible, i am using the hda connector.

I was just using this option for testing purpose. I do not need it ;)

i think it is the same problem like this one: https://bugs.launchpad.net/ubuntu/+source/pulseaudio/+bug/1248116

The audio source is switching very fast ... if i plug in the headphone to one front port the rate is just slowed down to every 5 seconds.

seem jack detection problem as headphone is changing from "plugged in" to "unplugged" 

you should check the front audio panel connector of the motherboard and your computer chassis front audio panel

the alternative is to set Misc = NO_PRESENCE (bit 8) of pin default of the headphone node by hda-verb or hdajackretask

Thx for your help!

I unplugged the front audio panel, problem still present!

hdajackretask fixed the noise(yeahh!), but is this a solution for the problem?

do your front mic have same sympton ? ( plugged and unplgged several times within same second in pulseaudio log )


may be related to unsolicited event of the headphone pin complex if the problem still present after you unplugged the front audio panel from the front audio panel connector of the motherboard


Suppose you built your kernel with the tracing support.  

See "Tracepoints" option in https://git.kernel.org/cgit/linux/kernel/git/tiwai/sound.git/plain/Documentation/sound/alsa/HD-Audio.txt

The hd-audio driver gives a few basic tracepoints.
`hda:hda_send_cmd` traces each CORB write while `hda:hda_get_response`
traces the response from RIRB (only when read from the codec driver).
`hda:hda_bus_reset` traces the bus-reset due to fatal error, etc,
`hda:hda_unsol_event` traces the unsolicited events


 echo 1 > /sys/kernel/debug/tracing/events/hda/hda_unsol_event/enable 

 cat /sys/kernel/debug/tracing/trace


check the trace to find out whether multiple unsol events are issued when the headphone is plugged
