[Realtek ALC1220 ASUS PRIME X370] Recording is very slow and plays 10x

record extremely slowly (at what seems to be 0,1x speed), which means
that at playback the sound is played at a very high pitch and much
faster than the original.

* Purging and reinstalling Audacity
* Purging and reinstalling Pulseaudio following the guide on the Ubuntu Wiki
* Running audacity with this command: Exec=env PULSE_LATENCY_MSEC=30
audacity as suggested on AskUbuntu
* Reinstalling Ubuntu on a new hard disk
* Running audacity on a live CD (in Ubuntu version 16.04.3, 17.10.1, 18.04
daily and Xubuntu 17.10.1, 18.04)
The machine is a Ryzen 5 1600 with an ASUS X370 Prime motherboard.
The problem can be reproduced as follows:
* Boot a live DVD of Ubuntu/Xubuntu 16.04.3, 17.10.1, 18.04 (versions I've
* Install audacity via the terminal
* Start recording, microphone is connected to the rear microphone jack.
