Description Gustaf Andersson 2020-02-22 06:22:55 UTC 
Created attachment 1664914 [details]
kernel log 5.5.5-200

1. Please describe the problem:

No sound after upgrading to the new kernel 5.5.5-200.fc31.x86_64 on a standard Fedora 31 workstation installation. In gnome sound panel it just registers a "Dummy output".

2. What is the Version-Release number of the kernel:

5.5.5-200.fc31.x86_64


3. Did it work previously in Fedora? If so, what kernel version did the issue
   *first* appear?  Old kernels are available for download at
   https://koji.fedoraproject.org/koji/packageinfo?packageID=8 :

Sound worked but not microphone.


4. Can you reproduce this issue? If so, please provide the steps to reproduce
   the issue below:

Run on a lenovo yoga s740 laptop. Boot kernel > 5.4.20


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.

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.
Comment 1 Gustaf Andersson 2020-02-22 06:41:01 UTC 
I read this: https://github.com/thesofproject/sof/issues/2264

and found this: https://bugzilla.redhat.com/show_bug.cgi?id=1772498

So this is probably a duplicate of that. Sorry.
