Bug#960788: ITP: alsa-sof-firmware -- Intel SOF audio firmware and topology

["Travis Cole" <kelp@plek.org>]

I have a new Thinkpad P1 Gen 3 and it's hitting this issue.

Seeing this in dmesg:

[   13.865530] sof-audio-pci 0000:00:1f.3: hda codecs found, mask 5
[   13.865531] sof-audio-pci 0000:00:1f.3: using HDA machine driver skl_hda_dsp_generic now

[   13.865830] sof-audio-pci 0000:00:1f.3: Direct firmware load for intel/sof/sof-cml.ri failed with error -2
[   13.865832] sof-audio-pci 0000:00:1f.3: error: request firmware intel/sof/sof-cml.ri failed err: -2
[   13.865833] sof-audio-pci 0000:00:1f.3: error: failed to load DSP firmware -2
[   13.866046] sof-audio-pci 0000:00:1f.3: error: sof_probe_work failed err: -2

For now I've worked around it by adding the following to /etc/default/grub:

GRUB_CMDLINE_LINUX="snd_hda_intel.dmic_detect=0"

So  I have audio, but no microphone.

But I'd love to see this firmware packaged and I'm happy to help test.

Thanks!
