[Ubuntu Kernel Bot (ubuntu-kernel-bot)]

This bug is missing log files that will aid in diagnosing the problem. While running an Ubuntu kernel (not a mainline or third-party kernel) please enter the following command in a terminal window:

apport-collect 1902457

and then change the status of the bug to 'Confirmed'.

That one works too.

[Kai-Heng Feng (kaihengfeng)]

Thanks, can you please attach dmesg under kernel lp1902457+2?

[Chris Kuethe (ckuethe)]

Attaching dmesg as requested

[Chris Kuethe (ckuethe)]

Problem still continues after upgrade to 5.8.0-38-generic #43-Ubuntu SMP Tue Jan 12 12:42:13 UTC 2021 x86_64 x86_64 x86_64 GNU/Linux

[Kai-Heng Feng (kaihengfeng)]

Can you please test this kernel:
https://people.canonical.com/~khfeng/lp1902457+3/

[Chris Kuethe (ckuethe)]

I would, but that appears to be a zero-length file - I'll check back in a few hours.

[Kai-Heng Feng (kaihengfeng)]

It was zero length, should be good now. Please check again.

[Chris Kuethe (ckuethe)]

Re installing linux-modules-extra, that doesn't help.

I tried this latest test kernel: it does not fix my audio, and it breaks my touchpad too.

[Kai-Heng Feng (kaihengfeng)]

Please give this another try, thanks!
https://people.canonical.com/~khfeng/lp1902457+4/

[Kai-Heng Feng (kaihengfeng)]

It includes this patch:
https://lore<email address hidden>/

[Chris Kuethe (ckuethe)]

Still no sound cards but at least my touchpad works again. Dmesg attached.

[Kai-Heng Feng (kaihengfeng)]

Thanks for testing. According to upstream dev, we need to enable more kernel config options. Please test this kernel:
https://people.canonical.com/~khfeng/lp1902457-enable-hda-codecs/

[Chris Kuethe (ckuethe)]

still no sound. see attached dmesg.

[Kai-Heng Feng (kaihengfeng)]

Can you please attach the dmesg under that kernel? Thanks!

[Chris Chiu (mschiu77)]

Could you add the following to /etc/modprobe.d/alsa-base.conf (and reboot):

options snd_hda_intel dyndbg=+p
options snd_soc_skl dyndbg=+p
options snd_soc_skl_hda_dsp dyndbg=+p
options snd_intel_dspcfg dyndbg=+p

Then provide the full dmesg results. Thanks!

[尉晓亮 (black96)]

confirmed the same issue running groovy on a Xiaomi redmibook(alc256m with intel dmic)， stock kernel detects dmic and drops to sst driver， which won't work at all， disabling dmic detection in alsa enables speakers but 3.5mm only works as mono，solutions about intel sst driver need to be backported if no new kernels are available in current distros.

[尉晓亮 (black96)]

And the following kernels don't work for me, still no soundcard
lspci: 00:1f.3 Multimedia audio controller [0401]: Intel Corporation Sunrise Point-LP HD Audio [8086:9d71] (rev 21)

[Cezary Rojewski (crojewsk)]

Hello,

Similar issue has been opened on bugzilla:
https://bugzilla.kernel.org/show_bug.cgi?id=212081

Whenever in doubt of skylake-hda_dsp configuration, please see:
Linux: HDA+DMIC with skylake driver
https://gist.github.com/crojewsk/4e6382bfb0dbfaaf60513174211f29cb

SND_SOC_INTEL_SKYLAKE_HDAUDIO_CODEC kconfig needs to be enabled for 'Skylake with HDAudio DSP + DMIC' configuration to work. Also, topology file is needed in /lib/firmware/. Linked gist should clarify these. If there's anything missing in the gist, please let me know so we can update the guide.

[Chris Chiu (mschiu77)]

Thanks for the quick answer @crojewsk. But I didn't see skl_hda_dsp_generic-tpkg.bin in linux-firmware repo yet. When can we expect the skl_hda_dsp_generic-tplg.bin or dfw_sst.bin in the linux-firmware?

[尉晓亮 (black96)]

tplg binary can be compiled with the .conf file provided with that repo, it should enable SST driver at least.
