I just had good success with adding a parameter to /etc/modprobe.d/alsa- base.conf:
options snd-hda-intel position_fix=1 I got the idea from: http://ubuntuforums.org/showthread.php?t=843012 And the file located at: /usr/share/doc/alsa-base/driver/ALSA-Configuration.txt.gz (use gunzip to unzip it) The section on snd-hda-intel contained the following: Note 2: If you get click noises on output, try the module option position_fix=1 or 2. position_fix=1 will use the SD_LPIB register value without FIFO size correction as the current DMA pointer. position_fix=2 will make the driver to use the position buffer instead of reading SD_LPIB register. (Usually SD_LPLIB register is more accurate than the position buffer.) My current configuration: Ubuntu 8.10, alsa 1.0.20, pulse audio 0.9.10, using equalizer via ladspa Pulse audio configuration files attached. The module parameter appears to be extremely important. ** Attachment added: "daemon.conf" http://launchpadlibrarian.net/26728537/daemon.conf -- Crackling noise after update to pulseaudio https://bugs.launchpad.net/bugs/301755 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
