1. Please describe the problem:
Starting with kernel 5,19, Intel engineers introduced new AVS module, which solves headaches of Chromebook users on SkyLake, KabyLake, ApolloLake and possibly GeminiLake (as well as refresh variants of those SoCs).

We (chrultrabook project) are currently testing kernel release 6.0. Despite Fedora providing mainline kernel repository, SND_SOC_INTEL_AVS_MACH_DA7219 isn't enabled by default, requiring kernel recompilation.

2. What is the Version-Release number of the kernel:
Mainline (6.0-rc*).


3. Did it work previously in Fedora? If so, what kernel version did the issue
   *first* appear?
N/A


4. Can you reproduce this issue? If so, please provide the steps to reproduce
   the issue below:
Booting kernel-vanilla-mainline	on those Chromebooks will result in no audio being detected.

With SND_SOC_INTEL_AVS_MACH_DA7219=m, as well as proper firmware and topology file and UCM, audio becomes fully functional (changes will be upstreamed in time for 6.0 release).

5. Does this problem occur with the latest Rawhide kernel? To install the
   Rawhide kernel, run ``sudo dnf install fedora-repos-rawhide`` followed by
   ``sudo dnf update --enablerepo=rawhide kernel``:
Yes


6. Are you running any modules that not shipped with directly Fedora's kernel?:
No, although current fc36 kernel (5.18) doesn't support avs at all.


7. Please attach the kernel logs. You can get the complete kernel log
   for a boot with ``journalctl --no-hostname -k > dmesg.txt``. If the
   issue occurred on a previous boot, use the journalctl ``-b`` flag.

The only message regarding AVS we can see on kernel-vanilla-mainline is:

8. Fix:
Please add SND_SOC_INTEL_AVS_MACH_DA7219=m to kernel configuration.
