you can trace hda_unsol_event find out whether exec_pin_sense is really needed by specify spec->no_trigger_sense = 1 in function patch_alc662 in patch_realtek.c since it is suppose to start the impedance measurement Tracepoints ~~~~~~~~~~~ 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, and `hda:hda_power_down` and `hda:hda_power_up` trace the power down/up via power-saving behavior. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1208218 Title: intermittent left-channel audio distortion To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/pulseaudio/+bug/1208218/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
