Description Michael Fryman 2021-11-04 22:40:30 UTC
Description of problem:
SELinux is preventing alsactl from using the 'setpgid' accesses on a process.

*****  Plugin catchall (100. confidence) suggests   **************************

If you believe that alsactl should be allowed setpgid access on processes labeled alsa_t by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
# ausearch -c 'alsactl' --raw | audit2allow -M my-alsactl
# semodule -X 300 -i my-alsactl.pp
