ALSA: No soundcards found after updating kernel to 5.3.0.42.36

[Atsushi Enomoto]

There seems to be some changes in ALSA in 5.3.0.41 and it seems to have caused some regression on my HP Spectrre (details attached).

~$ alsactl init
alsactl: init:1759: No soundcards found...

I verified that 5.3.0.40 works.

The same kernel update broke suspend: after resuming, the mouse and keyboard don't work -- just reporting here in case this helps locate the core issue.

[Hui Wang (hui.wang)]

5.3.0-43 is in the proposed, please try -43 kernel.

[Atsushi Enomoto (atsushieno)]

Thanks, with 5.3.0-43 it's working again.

[Gabriel Miranda (gabriel8fm)]

I have the same issue using notebook Dell G3-3590-A20P, my sound and microphone was gone when updated to Kernel 5.3.0-42.

Hos to upgrade to Linux Kernel 5.3.0-43?

[Gabriel Miranda (gabriel8fm)]

I installed kernel 5.3.0-050300 and sound and microphone works fine:

Linux G3-3590 5.3.0-050300-generic #201909152230 SMP Sun Sep 15 22:32:54 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux

I'm using Ubuntu 18.04.04 on Dell G3 3590-A20P.

[Jeremy Sanders (jeremysanders)]

I have the same problem on a Dell Inspiron 7590 (see #1868465). Suspend was also not properly working. The proposed kernel 5.3.0-43 on Eoan does not fix the missing sound device bug for me.

[Hui Wang (hui.wang)]

@Jeremy,

please upload dmesg with the kernel 5.3.0-43.

thx.

[Jeremy Sanders (jeremysanders)]

Please find dmesg output. I also verified that the linux-firmware package is not corrupted.

[Hui Wang (hui.wang)]

sof-audio-pci 0000:00:1f.3: Direct firmware load for intel/sof/sof-cfl.ri failed with error -2

@jeremy,

upgrade your linux-firmware.

sudo apt install linux-firmware.

[Jeremy Sanders (jeremysanders)]

@hui - I had the linux-firmware at the latest in the standard upgrades. I've just upgraded to updates-proposed (linux-firmware 1.183.5), but it still doesn't work:

[ 8.926091] sof-audio-pci 0000:00:1f.3: Direct firmware load for intel/sof/sof-cfl.ri failed with error -2
[ 8.926093] sof-audio-pci 0000:00:1f.3: error: request firmware intel/sof/sof-cfl.ri failed err: -2

I can't see any file sof-cfl.ri in the linux-firmware package.

[Hui Wang (hui.wang)]

Oh, it is a coffeelake machine. We don't support it yet. You could have a try with "sudo ln -s /lib/firmware/intel/sof-cnl.ri /lib/firmware/intel/sof-cfl.ri", then reboot. If it doesn't work, you could raise an issue on this website, maybe Intel could recommend the correct kernel and firmware. https://github.com/thesofproject/linux/issues/new

[Jeremy Sanders (jeremysanders)]

@hui Can you not revert the change to -40 version, as this is quite a serious regression in the middle of a release? The symlink works for me, however.

[Hui Wang (hui.wang)]

@Jeremy,

Many machines have their internal mic connected to the PCH, to make the internal mic work, the kernel needs those changes. And if you want the sound to work as before with -43 kernel, you could add "snd-hda-intel dmic_detect=0" in the /etc/modprobe.d/alsa-base.conf, then the audio will work as -40 or before.

thx.

[Bartosz Nowotny (bartoszn)]

Hi!

Sound still not working on -45, confirmed working on -40. Running Ubuntu 18.04.4 on Lenovo X1C 7th gen (just like https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1868165).

cheers

[Wolfgang Ratzka (wolfgang-ratzka)]

Hi!

Same here with an Acer Swift SF314-56G. Sound does not work on -45 but works on -46 (from proposed).

[Arnau (thealchemist886)]

Audio is still not working for me on -46 version of the kernel, dmesg attached.

[Jeremy Sanders (jeremysanders)]

@Arnau: It looks like yours is a coffeelake machine, like mine, which they don't support (see #12). The sound output worked originally in Ubuntu, but it was broken by these updates.

[Hui Wang (hui.wang)]

@Arnau,

Yes, just like Jeremy said, the firmware of cfl is not in the 19.10 or 18.04 yet. you could add the workaround of snd_hda_intel.dmic_detect=0 or manually ln a sof-cfl.ri, if it works well, I will consult with intel and add that link to ubuntu.

thx.

[Arnau (thealchemist886)]

@hui: Manually created symlink and rebooted, still does not work.

[Hui Wang (hui.wang)]

@Arnau,

please upload the dmesg after created the symlink.

thx.

[Arnau (thealchemist886)]

@hui: Here you go

[Hui Wang (hui.wang)]

@Arnau,

According to dmesg2, the firmware is still not loaded successfully. If you really created symlink for sof-cfl.ri, it looks like the firmware sof-cnl.ri is not suitable for cfl platform. please double check the symlink is correct: ls -la /lib/firmware/intel/sof

[Arnau (thealchemist886)]

@hui: okay, now it works, had to do "sudo ln -s /lib/firmware/intel/sof/sof-cnl.ri /lib/firmware/intel/sof/sof-cfl.ri", instead of "sudo ln -s /lib/firmware/intel/sof-cnl.ri /lib/firmware/intel/sof-cfl.ri" as in #12

[Bartosz Nowotny (bartoszn)]

Sound is back on -46 on my X1C 7th gen. Thanks for the fix!

[Pete Gamache (gamache)]

I concur, -46 fixed the issue on my X1C 7th gen. Thanks!

[Homan W (homanw104)]

Sound and microphone both fixed on my Dell Inspiron 7590 after doing "sudo ln -s /lib/firmware/intel/sof/sof-cnl.ri /lib/firmware/intel/sof/sof-cfl.ri". Thx!

[Ethan Lin (mainsystemadmin)]

If the issue looks fixed I can moved this to Fixed-released. Feel free to reopen if this is not fixed.
