Bug#949019: Missing firmware for sof-audio-pci
Dear Maintainer,
This issue is preventing audio working on a 7th generation Lenovo X1
Carbon (released 2019). After boot, no sound output device is
available. The following lines appear in dmesg:
[ 28.941465] sof-audio-pci 0000:00:1f.3: DSP detected with PCI
class/subclass/prog-if info 0x040380

I've searched on https://packages.debian.org/ and found no packages in
the archive with sof-cnl.ri. On Ubuntu 20.04, I see this file is available in
a package called "linux-firmware"
