For the sake of testing, I checked on the latest Impish daily image,
with kernel 5.11.0-18-generic. Same problem. dmesg attached. Alsa and
PulseAudio don't detect any sound card, even though in dmesg we can see:
$ sudo dmesg | grep -i snd

Title:
[Regression] Audio card [8086:9d71] not detected after upgrade from
linux 5.4 to 5.8
Status in linux package in Ubuntu:
Confirmed
Bug description:
Ubuntu version: 20.10 (updated from 20.04)
Kernel: 5.8.0-41-generic #46-Ubuntu
Manufacturer: Acer
Product Name: Swift SF314-54
BIOS Revision: 1.11
Audio card: Realtek High Definition Audio
Multimedia audio controller [0401]: Intel Corporation Sunrise Point-LP HD
Audio [8086:9d71] (rev 21)
Summary
=======
After upgrading from linux kernel 5.4 to 5.8, there is no more sound
card available. However, if I select kernel 5.4 in GRUB, the sound
card is available.
Steps to reproduce
==================
1. Install 20.04 or 20.10 with a kenel 5.4
2. Check that sound output works as excepted (Settings > Sound > Output >
Test)
3. Check that `alsa-info` command returns information
4. Upgrade kernel to 5.8
Expected results
================
Sound output still works.
Actual results
==============
2. Sound card is available, and sound can be output to the internal speakers.
4. No more sound card detected (Sound Settings display "Dummy Output" in the
list of output devices).
