It won't become normal until I set the mode to "Analog Stereo Output" first and then back to "Analog Surround 5.1 output" (or if I restart). I tried this: https://wiki.ubuntu.com/Audio/PositionReporting In the end, options snd-hda-intel position_fix=1 in /etc/modprobe.d/alsa-base.conf works perfectly (no crackling audio anymore). I also tried options snd-hda-intel position_fix=2 and the bug came back. --> Can you make a fix so it works out of the box ? Regards.
