i have additional information, by modifying settings in PowerTop i was able to reproduce the sound i hear while the machine is rebooting, including plugging my headphones in the jack.
By switching the option at "Enable Audio Code Power Management" at Good, i hear the sound and the static doesn't stop, at Bad it stops, however when i insert the jack i still hear the sound. The switching in powertop does the following GOOD echo ' ' > ' /sys/module/snd_hda_intel/parameters/power_save BAD echo '1' > ' /sys/module/snd_hda_intel/parameters/power_save -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1534434 Title: [20BVCTO1WW, Realtek ALC3232, Black Headphone Out, Right] Underruns, dropouts or crackling sound To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1534434/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
