2. What is the Version-Release number of the kernel:
5.7.6-201

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 :
The problem appeared with the 5.7.6-201 kernel. With the previous kernel 5.7.6-201, there is not.

4. Can you reproduce this issue? If so, please provide the steps to reproduce
   the issue below:
Just play any sound by booting the system with the 5.7.6-201 kernel.

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``:
I have not tried.

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.
