Thank you for reporting this bug to Ubuntu.

Daniel, over the span of this thread users have been experiencing this
on 18.04, the topic contains information regarding users (Including
myself) testing this on 18.04 and effects all distro's i know because of
a bug in the current version of the snd_hda_intel driver.

Having the same issue on the MSI X370 Gaming Pro Carbon, audio is fine
but the microphone is having weird behavior that differs depending on
configuration.
When audacity is launched it will trigger the bug that increases the
recording speed to be insanely high pitched and fast. Prior to using
I have the same issue on AsRock x370 Taichi with Ryzen 1700. The rear
audio output (green) hisses and crackles a lot on left channel, none of
the workarounds worked. Tested on Ubuntu 17.10 and 18.04

This also impacts me. ASRockx 399 Taichi, AMD Threadripper 1950x, and
this is impacting the mic/line in on the ALC1220 chipset. None of the
workarounds worked on my end. I ended up having to use some USB dongle
for audio input until this is resolved.

Same: ASUS Prime x470-pro, Ryzen 7 2700X, 4.18.0 kernel. Cracking sound
on the mic/line-in on ALC1220. The only thing, that somewhat helped, is
increasing the default-fragment-size-msec to 75+ at
/etc/pulse/daemon.conf. But it is a workaround, and it doesn't remove
the cracking fully.

I am affected by this bug. If I'm not mistaken all the individuals
affected by this bug are using AMD Ryzen? I see that the codec appears
to also be the AC1220. I'm using Asus x470-f gaming motherboard. I've
tried ALL the fixes on arch wiki (this include the tsched=0 fix in the
pulse audio config
I am also affected by sound crackling and sometime distortion since i swapped
motherboard for an ASUS X470 prime pro. It is present permanently on microphone
but sometimes affects other sources and applications.
The workaround above in the comments did not fix it for me.

Use this workaround which disables timer-based scheduling, which is the
root cause of the glitchy audio:
PulseAudio uses timer-based audio scheduling instead of the traditional,
interrupt-driven approach by default. This tends to expose issues in
some ALSA drivers, such as this glitch (observed
I wanted to add to the above, while the crackling was heavily present
for youtube, an mp3 played in clementine, and an mp4 video file in
smplayer, I ran ubuntu-bug -s audio, and the test tones were all clear,
except for a brief moment of static at the very last second. I ran the
test twice to

I've experienced this issue with a half dozen different A350/X370/X399
boards which all use AC1220. The mic noise is extraordinary and no
amount of tweaking pulseaudio seems to resolve it. Has anyone had any
success?

Example audio created with "arecord -f cd".
>From participants on various chat programs, the distortion is worse than
it sounds here, so I'm trying to figure out if I can get a second test
recorded via pulseaudio and not ALSA directly (I understand that is what
arecord does).
