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!

@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

@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,
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: 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.

Hi!
Same here with an Acer Swift SF314-56G. Sound does not work on -45 but

Hi!

@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
@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.

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

Please find dmesg output. I also verified that the linux-firmware

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.

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.
