( 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 <a href="https://git.kernel.org/cgit/linux/kernel/git/tiwai/sound.git/plain/Documentation/sound/alsa/HD-Audio.txt">https://git.kernel.org/cgit/linux/kernel/git/tiwai/sound.git/plain/Documentation/sound/alsa/HD-Audio.txt</a> 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</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> <li>You are the assignee for the bug.</li> </ul> </body> </html>
