The second patch cited in my previous post is necessary now (under
5.3.5, not sure about the previous kernel versions); besides the small
crackles when changing volumes, the acquisition from the microphone
under load (compilation, for example) sometimes becomes extremely low
quality (like if the sample rate is changing randomly and often the
audio is clipping). Applying the patch only on the capture stream
completely fix the issue, no crackles when changing volume and no issue
when acquiring audio with Discord under load.

Steam still shows random audio stutters while acquiring for a minute and
a bit of delay, so that is still unchanged, unfortunately.

Bug description:
  Not sure if I'll report this upstream but there is definitely an issue
  with microphone recording on my desktop, this is not happening on my
  laptop which has a different codec.

  Already tried all workarounds possible, no luck. Only with my desktop
  with this particular motherboard. No issues in Windows, the sound
  recorded in there is distorted and has some static and robotic tone on
