I am experiencing a similar issue, which is a regression that started after an update on Monday (Oct 12) night. I started hearing loud popping noises from the speakers, perhaps 30 seconds apart.
After reading this bug (and 383385, 444385) I found I was able to reproduce the pop by opening the sound preferences dialog, and waiting for at least 10 seconds before clicking on "Mute" or "Enable window and button sounds" (didn't matter which and didn't matter if I was checking or unchecking the box). The longer I waited, the louder the popping sound. Editing /etc/modprobe.d/alsa-base.conf, changing the line options snd-hda-intel power_save=10 power_save_controller=N to read options snd-hda-intel power_save=0 power_save_controller=N and rebooting appears to have fixed the issue for me. I'm not hearing the pops and I can't trigger them with the sound preference dialog. -- Regression: frequent popping sound with light indicating that sound is supposed to be muted https://bugs.launchpad.net/bugs/442463 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
