David, cool! We're not there yet, but it's an improvement! What I have found out:
1. Having 'options snd-hda-intel power_save=10 power_save_controller=N' enabled: * When I clean boot notebook, the crackling is not audible in speakers, but if you plug headphones you can hear it. * When you suspend and resume notebook, the crackling is much louder so you can hear it even in speakers. * The crackling occurs on every mute and unmute. When you unmute, the crackle also repeats after several seconds (several, up to 10 sec). Also the crackle appears after every sound (system beep etc) in the same interval as for unmute. 2. Having 'options snd-hda-intel power_save=10 power_save_controller=N' commented out: * First two lines of 1) are still valid. * The crackling occurs on every mute and unmute. But it doesn't repeat itself after any interval after unmute, nor it happens after any system beep. Therefore 2) is clearly improvement, now it crackles only on mute/unmute, not all the time. But, I don't think there is a problem with powersaving (the 10 seconds interval) per se. It seems to me that that feature is working well. What is not working well is the crackle on mute/unmute. If that is solved, I don't have any problem with powersaving feature. ** Changed in: pulseaudio (Ubuntu) Status: Incomplete => New -- Regular crackling sound on ThinkPad R61 https://bugs.launchpad.net/bugs/500987 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
