Comment 96 for bug 1801540

Using arecord still trigger the cracking sound (and according to the manpage, this program records directly from ALSA). However, using Audacity and manually selected the audio acquisition device coming from the ALSA driver and not the audio from PulseAudio, that have the same problems of the rest of the software. Result = clean and crispy sound (with PulseAudio still running in background). Before trying that I've stupidly tried to play with all the parameters from the exposed hda driver, to no avail. Dumped the pinconfigs from Windows, and compared to the ones set by Linux, to see if there was any additional parameters passed to the HDA controller that was fixing the problem. Nothing.

I'll assume that the problem lies in PulseAudio and not ALSA (even if I can't explain to myself why arecord still have the same problem through ALSA and not Audacity). Unfortunately, a lot of software on Linux can't speak directly through ALSA, so I'm stuck for now.
