Public bug reported: Following these instructions.
Hi all, "Luke and I have just pushed a one-line change to 9.10's /etc/modprobe.d/alsa-base.conf that enables HDA controllers to power down their amps after ten idle seconds. This change anticipates the larger power-savings objectives for 9.10. We expect there will be regressions in the form of audible pops when the AMPs power down (and/or up). If you experience this symptom in 9.10, please file a bug using "ubuntu-bug alsa-base". Be sure to change the summary of the bug afterward to "[9.10 regression] HDA power_save=10". Thanks, Dan" ProblemType: Bug Architecture: i386 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC0: dl 3212 F.... pulseaudio Card0.Amixer.info: Card hw:0 'Intel'/'HDA Intel at 0xf4780000 irq 16' Mixer name : 'Analog Devices AD1981' Components : 'HDA:11d41981,103c30ad,00100200 HDA:11c13026,103c30ad,00100700' Controls : 13 Simple ctrls : 11 Date: Thu Sep 10 18:22:15 2009 DistroRelease: Ubuntu 9.10 Package: alsa-base 1.0.20+dfsg-1ubuntu4 PackageArchitecture: all ProcEnviron: LANG=en_US.UTF-8 SHELL=/bin/bash ProcVersionSignature: Ubuntu 2.6.31-10.30-generic SourcePackage: alsa-driver Uname: Linux 2.6.31-10-generic i686 ** Affects: alsa-driver (Ubuntu) Importance: Undecided Status: New ** Tags: apport-bug i386 -- [9.10 regression] HDA power_save=10 https://bugs.launchpad.net/bugs/427645 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
