Bug description:
[SRU Justification]
[Impact]
Skylake, Kabylake, Kabylake-refresh, Amberlake and some other platforms where
audio is of SPT (PCH) type, HDA (with DSP capabilities) plus DMIC configuration
is supported on these with skylake driver since kernel 5.8. However, no sound
card can be detected w/o the topology binary file in /lib/firmware and
corresponding ucm file.
[Fix]
The kernel config CONFIG_SND_SOC_INTEL_SKYLAKE_HDAUDIO_CODEC needa to be
enabled for the snd_soc_skl driver to support HDA+DMIC configuration. And the
topology binary file and UCM files need to be located in the correct path based
on Intel's suggestion.
https://gist.github.com/crojewsk/4e6382bfb0dbfaaf60513174211f29cb.
[Test]
On the Skylake/Kabylake platforms with either the PCI device 8086:9d70 and
8086:9d71, boot up the machine and check the existence of the sound card by
either 'aplay -l' or 'pactl list' command.
[Where problems could occur]
Should be low risk, it only affects limited Intel Platforms with particular
PCI device IDs + HDA plus DMIC configuration.
========== Original 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).
